Fenbendazole and Ivermectin for Pancreatic Cancer Success Stories: 20 Case Reports (June 2025 Edition)

Can Fenbendazole and Ivermectin play a key role in treating Stage 4 Pancreatic Cancer?

Several studies and case reports (below) strongly suggest that it might. 


Introduction: Exploring Fenbendazole as a Potential Treatment for Stage 4 Pancreatic Cancer

Pancreatic cancer is among the most aggressive and difficult cancers to treat, particularly in its later stages. Approaches to improve pancreatic cancer therapy are essential as this disease has a very bleak outcome. Approximately 80% of pancreatic cancers are pancreatic ductal adenocarcinomas (PDAC). PDAC is a cancer which is difficult to effectively treat as it is often detected late in the disease process. Almost all PDACs (over 90%) have activating mutations in the GTPase gene KRAS.

Pancreatic cancer has a high mortality rate and is often resistant to conventional treatments. Standard therapeutic options include surgical resection, chemotherapy, and radiation therapy, yet survival rates remain low. Recently, alternative treatment strategies have gained interest, including the repurposing of existing drugs originally developed for non-cancer indications. 

Given the limited success of conventional treatments, many patients and researchers are turning to alternative and complementary therapies. Two such options gaining attention are fenbendazole and ivermectin—well-known antiparasitic drugs traditionally used in veterinary medicine—now being explored for their potential anti-cancer properties.

Using SEER* 5-year survival statistics: Public median survival ~3–6 months post-diagnosis vs. multiple cases reporting survival beyond 1 year with fenbendazole and ivermectin below.

*The Surveillance, Epidemiology, and End Results (SEER) Program provides information on cancer statistics in an effort to reduce the cancer burden among the U.S. population. SEER is supported by the Surveillance Research Program (SRP) in NCI's Division of Cancer Control and Population Sciences (DCCPS).

In this article, we examine and compile case studies of fenbendazole and its possible role in managing pancreatic cancer. Could this repurposed drug offer new hope for patients seeking additional treatment options? Let’s take a closer look.
 

Pancreatic Cancer Success Stories

Case No. 20 - 2025: Canadian with stage 4 pancreatic cancer who was offered euthanasia

A patient with stage 4 pancreatic cancer who was offered euthanasia (Medical Assistance in Dying, MAID) is cancer-free a few months later.

A Canadian patient developed pancreatic cancer 6 months after receiving a COVID vaccine. 
He had surgery to remove it, but 15 months later, CT scans showed a recurrence of stage 4 pancreatic cancer, including metastases to the lungs.

This patient with stage 4 pancreatic cancer was offered typical Canadian cancer care:

“I was immediately visited by social workers to discuss end of life and MAID (medical assistance in dying or euthanasia).

In addition to palliative chemotherapy, Dr. Makis’ treatment was:
  • Fenbendazole 444 mg/day for at least 3 months
  • Fenbendazole 444 mg/day with liquid ivermectin (1 teaspoon) = 50 mg for 2 months.
Results:

“The CT scan showed that all signs of cancer were undetectable and essentially resolved.”

In Dr. Makis’s clinical experience, pancreatic cancer responds very well to the combination of ivermectin and fenbendazole.

Ivermectin kills cancer cells that chemotherapy fails to kill. Ivermectin also reverses multidrug resistance (chemo resistance).

The patient’s primary oncologist was shocked by the sudden turnaround, but most importantly, this patient managed to avoid Canada’s first approach to cancer care: euthanasia.

Case No. 19 - 2025: 66 year old Netherlands Man with Stage 4 Pancreatic Cancer with a solitary liver metastasis

Dr William Makis shared on X (Twitter) in June 2025:

IVERMECTIN and FENBENDAZOLE Testimonial - 66 year old Netherlands Man with Stage 4 Pancreatic Cancer with a solitary liver metastasis. In 4 months, it shrunk by 99.7%! Shocking story! There is an extremely important lesson here! I absolutely love this Pancreatic Cancer success story. 

66 year old Netherlands man was diagnosed with Stage 4 Pancreatic Cancer in Oct.2024 with a solitary liver metastasis.
  On January 31 2025 we started:
  • Ivermectin 1mg/kg/day 
  • Fenbendazole 888mg/day (briefly increased to 1776mg/day then 1332mg/day but he went back down to 888mg/day)
Feb.19, 2025 Oncologist started FOLFIRINOX Chemo After 5 weeks (Mar.7) lesion INCREASED 34.7mm to 40.1mm After 10 weeks (Apr.11) lesion DECREASED from 40.1mm to 35.8mm After 4 months (Jun.3) lesion DECREASED from 35.8mm to 11.1mm (99.7% volume shrinkage!!) What’s very interesting in this case is that the liver lesion got mildly larger after 5 weeks, before it started shrinking. The other possibility is that it remained unchanged in size as we were comparing CT (34.7mm) to MRI (40.1mm) measurements, which are different imaging modalities. Regardless, the liver lesion didn’t improve for at least 5 weeks! However, by the end of 4 months, the lesion had shrunk by 99.7% in tumor volume!! This is WHY you don’t quit after 1 month!


Case No. 18 - 2024: 36 year old mom of 4 with Recurring Pancreatic Cancer

January 2025 post by Dr William Makis

IVERMECTIN Testimonial - Incredible story from a 36 year old mom of 4 with Pancreatic Cancer (possibly Turbo Cancer), whose case was botched by Oncologists, she took Ivermectin and is now Cancer Free! This is an amazing story of courage and resilience that every cancer patient should read! Emily Ziegler Faced Pancreatic Cancer at age 36. I will summarize what is a somewhat complicated medical story: 36 year old mother of 4, was diagnosed with Stage 2 Pancreatic Ductal Carcinoma (PDAC), wrapped around her blood vessels, preventing her from getting surgery. She did 6 months of chemo, which shrunk the tumor away from the blood vessels just enough to allow her to have surgery (Whipple procedure). The tumor that was removed, however, was twice the size of the original tumor, indicating the Pancreatic Cancer had already overcome the effects of the chemo even before the surgery and had been growing again very quickly. Surgeons claimed they got it all but they didn’t (post op pathology report showed positive margins but no one caught it and no one seemed to know) She had ongoing symptoms but wasn’t taken seriously by her Oncologists. Her cancer markers CA-19 spiked and sure enough, 8 months after her surgery she was diagnosed by CT with a Pancreatic cancer recurrence, nearly the same size as the 1st tumor, but her Oncologists refused to treat her and tried to put her on a trial of some kind. At this point it becomes a medical horror story. She went to MD Anderson for a second opinion. Fortunately, this is where she started taking Ivermectin on the advice of her mother in law: “my mother in law knew of Dr.Makis and his research”. She took Ivermectin for three months while arranging a new cancer team to prepare treatment for her Pancreatic Cancer recurrence. During those three months the tumor STOPPED growing, was unchanged on CT and had not metastasized (!!) Her 2nd (more competent) Oncology team then did 6 weeks of chemo and radiation with incredible results. She is now Cancer free! What actually happened here? How do I explain what happened here? During the 3 months that she was diagnosed with a LOCAL Pancreatic cancer recurrence but her Oncologists refused to treat her, the Ivermectin definitely stopped the tumor growth. Without the Ivermectin she would have progressed to Stage 4 with metastases - this was a very aggressive cancer! Ivermectin stopped the tumor growth and prevented the tumor from metastasizing! But it doesn’t end there. Furthermore, Ivermectin sensitized her cancer to the chemo and radiation that she then received: “they did just 6 weeks of chemo paired with a small bit of radiation 5x a week”. Let's bring in the science: Ivermectin kills stem cells, making it possible to reach NED post chemo and radiation (2017 Dominguez-Gomez et al: “Ivermectin as an inhibitor of cancer stem-like cells”) Ivermectin inhibits tumor growth and metastasis (2020 Chen et al: “Ivermectin suppresses tumour growth and metastasis through degradation of PAK1”) Ivermectin inhibits metastasis (2022 Jiang et al: “Ivermectin inhibits tumor metastasis by regulating the WNT/b-catenin/integrin b1/FAK signaling pathway”) Ivermectin reverses chemo drug resistance, allowing chemo to kill more cancer cells (2019 Jiang et al: “Ivermectin reverses the drug resistance in cancer cells through EGFR/ERK/Akt/NF-kB pathway”) Ivermectin sensitizes cancer cells to radiation, allowing radiation to kill more cancer cells. (2020 Mudassar et al: “Targeting tumor hypoxia and mitochondrial metabolism with anti-parasitic drugs to improve radiation response”)

"Where can I add my ivermectin testimonial? It helped me beat pancreatic cancer!" (source)

"I had pancreatic cancer. When I was having a recurrence, I was denied treatment. My doctor went as far as withholding one of my scans to delay me going elsewhere. I could've died in the 3 months it took to get that scan and new care team set up. We'll my mother in law heard Dr. Makis talk about this. She told me to take it. So I did. For 3 months the tumor saw ZERO changes. Then new care team delivered only 6 weeks of chemo/radiation and my scans shortly after showed that the tumor was completely gone!" (source)

"What I'm saying is that with my type of cancer, it doesn't just stop growing. It grows fast and takes you down quickly. That 3 months of no treatment, I should've been dead. Ivermectin stopped the cancer cells from replicating. The chemo finished clearing it out. Compared to how the first tumor growth rate and the second, for this to just suddenly stop is absurd!"

Case No. 17 - 2025: 67 year old Maryland woman was diagnosed with a Pancreatic Cancer 2.3cm, failed 3 months of chemo with Stage 4 spread to the liver

Dr William Makis shared on X (Twitter) in June 2025:

IVERMECTIN and FENBENDAZOLE Testimonial - 67 year old Maryland woman was diagnosed with a Pancreatic Cancer 2.3cm, failed 3 months of chemo with Stage 4 spread to the liver. She is now Cancer Free! From Stage 4 Pancreatic Cancer to CANCER FREE in 2.5 months! Due to recent attacks, I will be posting even more testimonials STORY: 67 year old Maryland woman was diagnosed with Pancreatic Cancer, a 2.3x2.2cm Pancreatic Head Mass She had 3 months of neoadjuvant chemotherapy with FOLFIRINOX from Sep.30, 2025 to Jan.2025 but MRI done Jan.7, 2025 showed no improvement and a suspicion of progression to Stage 4 with new liver metastases. After failing chemo, this patient reached out to me. In early March 2025 we started: Ivermectin 1.5mg/kg/day Fenbendazole 1000mg/day CBD Oil 100mg/day RESULTS after 2.5 months: CT May 20, 2025: “Previous mass pancreatic head is no longer visualized” “Images of the liver…previous small enhancing nodules are not seen” CA19-9 also dropped from 942 to 9. My Take… Big Pharma shills will always say that it was the chemo that did all the work in these cases and that Ivermectin and Fenbendazole didn’t do anything. Here you have a case of a 67 year old woman with a 2.3cm Pancreatic Head Cancer who didn’t respond at all to FOLFIRINOX chemo and instead progressed to Stage 4 with liver metastases. Add Ivermectin and Fenbendazole and 2.5 months later, both the Pancreatic mass and liver lesions are GONE. The patient is currently CANCER FREE!

"Hi Dr.Makis, enclosed is the latest scan and it's outstanding. Thank you and your team for everything. You are a God send".


Case No. 16 - 2025: 78 year old California man with poorly differentiated Stage 4 Neuroendocrine Pancreatic Cancer

Dr William Makis shared on X (Twitter) in June 2025:

IVERMECTIN and FENBENDAZOLE Testimonial - 78 year old California man with poorly differentiated Stage 4 Neuroendocrine Pancreatic Cancer had a dramatic response after 3 months! Poorly Differentiated Neuroendocrine cancers are considered almost impossible to treat, by mainstream Oncology. STORY: 78 year old California man was diagnosed with Stage 4 NEUROENDOCRINE Pancreatic Cancer (10cm mass) metastatic to the liver We started: Ivermectin 1.0mg/kg/day Fenbendazole 1500mg/day CBD Oil 100mg/day RESULTS: after 3 months (PET May 2, 2025) Pancreatic Mass 10.4x8.2x6.2cm to 8.3x2.4cm = 77% tumor volume reduction of primary tumor Liver metastasis 4.6x4.4cm to 1.4x1.3cm = 97.3% tumor volume reduction Liver metastasis 4.3x3.7cm to 2.7x2.2cm = 77.8% tumor volume reduction left adrenal metastasis 3.1cm to 2.1cm = 68.9% tumor volume reduction upper abdominal lymph node 8mm resolved = 100% tumor volume reduction I run the world's largest Ivermectin Cancer Clinic and we are being attacked for helping thousands of Cancer patients from around the world. The synergy between Ivermectin, Fenbendazole and chemotherapy is giving results that often shock the Oncologists. From the patient's family: "he seems to be responding exceptionally well to treatment" And it's nice when patients recognize the efforts undertaken to get them these kinds of results "I wanted to first of all extend a huge thank you to you for your help with my dad's case. And also for your continued determination and courage with your research and patient care" "I realize you have come under a lot of fire and I admire and commend your willingness to speak out and to continue fighting against the corruption." "We need more expert voices like you in this world!"


Case No. 15 - 2025: 66 year old man with Stage 4 Inoperable Pancreatic Cancer on 3rd line chemo and growing pancreatic mass

Dr William Makis shared on X (Twitter) in May 2025:

IVERMECTIN and MEBENDAZOLE Testimonial - 66 year old man with Stage 4 Inoperable Pancreatic Cancer on 3rd line chemo and growing pancreatic mass - gets cancer under control with tumor shrinkage! As the Big Pharma attacks escalate, I will post even more Cancer Success stories! No one ever talks about chemotherapy failure rates, I wonder why that is. Most of the cancer patients who come to me from around the world are failing chemo after chemo after chemo after chemo... STORY: 66 year old man with inoperable Stage 4 Pancreatic Cancer had been on: mFOLFIRINOX from Oct.2023 to May 2024 Gemcitabine/Abraxane from May 2024 Added Cisplatin June 2024 due to increasing CA19-9 Switched Cisplatin to Oxaliplatin Feb.2025 due to increasing CA19-9 His Oncologists call this two lines of chemotherapy but I count four...all failed...but I digress... Patient came to me in January 2025 with a growing pancreatic mass: "Gemcitabine and cisplatin and abraxane which brought numbers down and stable tumor but now that has worn off - tumor in pancreas growing and number getting larger CA19-9." Chemo seems to fail so often, doesn't it? We started early February 2025:
  • Ivermectin 1.5mg/kg/day
  • Mebendazole 1500mg/day
RESULTS: "Numbers came immediately down" "Scan much better after 2 months - oncologist relayed they don't often see "decrease" in tumor size at his stage" There's a lot these inept Oncologists don't see. After only 2 months of Ivermectin and Mebendazole: CA19-9 dropped from 146 to 9.5 Pancreatic mass shrunk from 2.8x1.9cm to 2.8x1.5cm (21% volume shrinkage) Ideally this patient would have had a PET/CT scan that could have shown us a significant drop in metabolism of the tumor. Whenever you see Ivermectin and Mebendazole attacked, it’s important to understand that these patients are PROGRESSING on chemo after chemo after chemo. And these failing chemos are the BEST that modern medicine has to offer. To get control of a Stage 4 Pancreatic Cancer like this after so many attempts at chemotherapy, is nothing short of a miracle.

Case No. 14 - 2025: 63-year-old woman in Philippines with Stage 4 Pancreatic Cancer

Dr William Makis shared on X (Twitter) in May 2025:

IVERMECTIN and FENBENDAZOLE Testimonial - 63 year old woman in Philippines with Stage 4 Pancreatic Cancer sees 80% tumor shrinkage after 1 month! This is a beautiful international cancer success story! (and a reminder you won't find these successes anywhere else) When you run the world's largest Ivermectin Cancer Clinic, patients come to you from around the world. STORY: 63 year old woman in the Philippines had recently progressed to Stage 4 Pancreatic Cancer with liver metastases. We started in mid February 2025:
  • Ivermectin 1.5mg/kg/day
  • Fenbendazole 1500mg/day
RESULTS after 1 month: Pancreatic mass shrunk from 5.3x5.4x5.5cm to 3.6x3.1x2.7cm = 81% TUMOR VOLUME SHRINKAGE. Fascinatingly, CEA went from 36 to 107 to 32.8 during this time. Possible explanation: rapid cancer cell killing caused CEA to rise temporarily. From the patient: "We have an exciting update!...a HUGE improvement on her pancreatic tumor size" "We're so excited by the reduction in her tumor size! Nothing short of a miracle! But CEA seems to have increased which we are confused about? Why is this so?" "We just received our latest CEA labs...good news!" CEA Tests: 1. Jan.2025 - 36 2. Mar.2025 - 107 3. Apr.2025 - 32.77 "God bless you always Dr.William Makis!!" I love my cancer patients. Aren't they the best?
So this was 1 month on gemcitabine + paclitaxel + Ivermectin (96mg) + Fenbendazole 1554mg.

Ivermectin and Fenbendazole Testimonial - 46 year old USA man with Stage 4 Pancreatic Cancer sees dramatic improvement after 2 months! How about a Pancreatic cancer success story? (Don't tell the Oncologist) STORY: 46 year old USA man was diagnosed with Stage 4 Pancreatic Cancer metastatic to liver and lungs, in Oct.2024 CT showed a 2.8cm pancreatic mass with innumerable lung nodules, and metastatic disease in the liver up to 7.9cm In early February 2025 we started:
  • Ivermectin 1.5mg/kg/day
  • Fenbendazole 2000mg/day
RESULTS after 2 months: CA19-9 cancer marker drop from 138 to 40.6. CT: “Overall decreased size of the pulmonary and hepatic metastases” “Pancreatic mass with peripancreatic lymph node is slightly decreased” “decreased now trace pelvic ascites” I always get asked about ascites - yes, Ivermectin and Fenbendazole can reduce and eventually eliminate ascites! From the patient: "I just received the following response from my oncologist: "Congrats! The Cancer treatment is working and the cancer is shrinking"
I have been helping Oncologists pat themselves on the back for success they didn't earn, ever since I started my Ivermectin Cancer Clinic one year ago. They sure get excited about the amazing results, but have no idea that Ivermectin, Fenbendazole and Mebendazole are doing the heavy lifting!

Case No. 12: 57 year old California man with Stage 2 Pancreatic Cancer

Dr William Makis shared on X (Twitter) in April 2025:

IVERMECTIN and FENBENDAZOLE Testimonial - 57 year old California man with Stage 2 Pancreatic Cancer (history of two Moderna mRNA vaccines) has excellent response after only 2 months!

"His oncologist is aware of the supplements he is taking (she's not so happy about it)"
I almost fell off my chair...I love when my patients write to me about their interesting interactions with their Oncologists! But let's go to the beginning... 57 year old California man was diagnosed with Stage 2 Pancreatic Cancer with a 3.6cm mass in the head of the Pancreas. He had two Moderna mRNA Vaccines. Was this an mRNA Induced Turbo Cancer? Possibly. December 2024: "After waiting for a chemo date and without a Protocol in place, his CA19-9 rose from 1341 to 2244 in 11 days!" Yes, very possibly a Turbo Cancer. This kind of growth in Cancer markers is absolutely frightening... He came to me in early January 2025. He started chemo on Jan.29, 2025 along with: 
  • Ivermectin 96mg/day
  • Fenbendazole 1776mg/day
Those of you who know me, know I prefer to work with higher doses. The Stanford Group used Fenbendazole 1000mg/day but for Pancreatic Cancer, I like to go higher. RESULTS after 2 months: CA19-9: 2244 to 914 to 1328 to 601 to 426 (after 2.5 months) PET/CT: Pancreatic mass SUV 5.0 to 2.7 (46% drop in metabolic activity) These are incredible results for a Pancreatic Turbo Cancer! Cancer blood markers dropped 81%, metabolic activity of pancreatic tumor dropped 46%!


Case No. 11: 46 year-old-male with Stage 4 Pancreatic Cancer

Dr William Makis shared on X (Twitter) in April 2025:

IVERMECTIN and FENBENDAZOLE Testimonial - Stage 4 Pancreatic Cancer post Moderna mRNA Vaccines - 46 year old USA patient improves dramatically after only 2 months! All tumors and metastases shrink! This family has two incredible Pancreatic Cancer success stories from my Ivermectin Cancer Clinic! STORY: 46 year old man (USA) was diagnosed with Stage 4 Pancreatic Cancer metastatic to lymph nodes, liver and bones. He had two Moderna COVID-19 mRNA Vaccines in 2021. (Possible Turbo Cancer) Oncologist started Folfirinox and Gemcitabine

We started the Makis Ivermectin Cancer Clinic Protocol:
  • Ivermectin 1.5mg/kg/day 
  • Fenbendazole 1500mg/day
A follow-up PET/CT was done after 2 months on Ivermectin Protocol RESULTS: After 2 months on Ivermectin and Fenbendazole:

Pancreatic head mass shrunk by 21% with 56% drop in metabolism
Lymph node metastases improved or resolved

Liver metastases reduced by 40-45% in number.
Bone metastases improved or resolved.

You never see this kind of response with just chemo. In only 2 months!! This patient was referred by a family friend: "Hi Dr.Makis...just want to let you know that my uncle who has been on your Protocol since September 1st has seen drastic improvement, his most recent scan showed the tumor in his pancreas has shrunk. This is something the oncologists said was nearly impossible.

However, the main reason for my email is to try and help a family friend with HIS cancer...he has stage 4 pancreatic cancer which has spread to many other organs, his situation is somewhat dire". That's the case described here with the pancreatic mass and all metastases shrinking after 2 months on Ivermectin and Fenbendazole.

FENBENDAZOLE and MEBENDAZOLE Testimonial - 77 year old Stage 4 Pancreatic Cancer patient sees 99.9% drop in CA19-9 levels and shrinkage of tumors by 70 to 87%! 

Another incredible Stage 4 Pancreatic Cancer success story!  This one may surprise you because Ivermectin was not involved. 

77 year old Stage 4 Pancreatic Cancer patient started taking a regimen of Mebendazole and Fenbendazole.

1000mg Mebendazole in the morning 
888mg Fenbendazole in the afternoon 

RESULTS: 
- CA19-9 dropped from 44960 to 21 (99.9% drop) 
- small liver lesions resolved - large liver lesion shrunk from 3.6cm to 2.4cm (70% tumor volume decrease) 
- 2nd liver lesion shrunk from 2.4cm to 1.2cm (87% tumor volume decrease) 

"His Doctors are amazed. His main oncologist told him in 35 years he does not remember a person with results like this. He went as far as calling the results a miracle." 

" Dr. Makis, you have saved countless lives with your message, you are the epitome of what health care should be. Thank you" 

Very nice to see a Stage 4 Pancreatic Cancer testimonial using Fenbendazole and Mebendazole!


Case No. 8: Stage 4 Pancreatic Cancer

Dr George Fareed shared on X/Twitter (January 2025):

"Patient with stage 4 pancreatic cancer today txted: Great news. Tumor is much smaller than before. 5.4cm to 3.3 cm. I’ve gained about 12 lbs. He continued IVM/mebendazole protocol started 10/24 as well as chemo started 11/24."
 

Case No. 7: 40s-yr-old male with Stage 4 Pancreatic Cancer (December 2024)

Case shared by Dr William Makis (X/Twitter):

IVERMECTIN and FENBENDAZOLE Testimonial - 40s year old man with Stage 4 Pancreatic Cancer post 2x Pfizer mRNA Vaccines, sees 91% drop in CA19-9* in 2 months! Possible case of Turbo Cancer post 2 Pfizer COVID-19 mRNA Vaccines 40s year old man diagnosed with Pancreatic cancer in 2022 post 2 Pfizer COVID-19 mRNA Vaccines. Had Whipple procedure, then 12 cycles of chemo and 2 months of radiation. Treatments ended May 2023.
Recurrence in June 2024 (mass encasing SMA & liver lesions) Restarted chemo in July 2024 but chemo wasn't working. CA19-9 was skyrocketing. I was consulted in October 2024. We immediately started high dose Ivermectin (up to 2mg/kg/day) and high dose Fenbendazole (up to 888mg/day) 2 months later: (you can read the email for yourself) 91% drop in CA19-9 cancer blood markers! 28340 to 2699. This is my favorite part, seeing results like this, especially when chemo was failing. It's worth persevering on high doses of Ivermectin, Fenbendazole or Mebendazole, and i know it isn't always easy. We struggle with this sometimes.






*Note on pancreatic cancer marker (CA 19-9):

A CA 19-9 test measures the amount of a protein called CA 19-9 (cancer antigen 19-9) in a sample of your blood. CA 19-9 is a type of tumor marker. Tumor markers are substances made by cancer cells or by normal cells in response to cancer in your body. Healthy people can have small amounts of CA 19-9 in their blood. High levels of CA 19-9 are often a sign of pancreatic cancer. But high levels can also be a sign of other types of cancer or certain conditions that aren't cancer. For example, gallstones, pancreatitis and cirrhosis of the liver can cause high CA 19-9 levels.


Case No. 6: Pancreatic Cancer patient who didn’t respond to first line chemotherapy (November 2024)

Case shared by Dr William Makis (X/Twitter):

IVERMECTIN and FENBENDAZOLE Testimonial - Pancreatic Cancer - CA19-9 drops 1349 to 450 in less than 2 months - loving daughter outsmarts Oncologist! This is a Pancreatic Cancer patient who didn’t respond to first line chemotherapy, the best chemo that the Oncologists had in their arsenal. Lessons: Oncologist with his best medical training and best medicine = Pancreatic tumor grows 4.1cm to 4.6cm and CA19-9 rises 880 to 1349 Loving daughter with internet and dog medicine = CA19-9 drops 1349 to 450. Low doses can work: 
12mg Ivermectin (I would have done 60mg) 
444mg Fenbendazole 4/7 
(I would have done 6/7 or even 888mg) She still did brilliantly. Work with what you have and don't be afraid. The daughter outsmarted the best Oncologists with their best medicine!



Case No. 5: 50s man with Stage 3 Pancreatic Cancer (November 2024)

Case shared by Dr William Makis (X/Twitter):

IVERMECTIN and FENBENDAZOLE Testimonial - 50s man with Stage 3 Pancreatic Cancer - incredible response to therapy after 8 weeks - 75% drop in CA19-9

75% reduction in blood tumor marker CA19-9 after only 8 weeks of high dose Ivermectin and Fenbendazole is wild! We’re certainly on the right track. 

75% of cancer cells may be dead, no longer producing tumor markers. Excellent question and lesson point here. Is it problematic that the tumor is not shrinking yet? 

That takes a bit longer and is a more involved process. That’s why a PET/CT scan would be good here. We could see the metabolic activity of the tumor drop dramatically, suggesting most of the cancer cells are dead, even if the tumor mass hasn’t shrunk yet. 

Some Oncologists are good at ordering them, some aren't. 

It takes time for the body to re-absorb or clear dead tumor cells from a solid mass. The tumor mass could be 75% dead cells and still appear unchanged in size. Eventually the body does get to mopping it up, though.



Case No. 4: Male with terminal Stage 4 pancreatic cancer (October 2024)

Posted by Dave on X.com:

My dad is still alive today 2.5 years after a terminal stage 4 pancreatic cancer diagnosis thanks to MEBENDAZOLE. His pancreatic tumor has been undetectable for 2 years.

Note: Although technically mebendazole is not the same as fenbendazole, both mebendazole and fenbendazole are part of a larger group of drugs known as benzimidazole*, which are anthelmintic drugs (i.e., drugs that kill parasitic worms).

*The class of drugs known as benzimidazoles includes fenbendazole, mebendazole, albendazole and flubendazole.

Fenbendazole and mebendazole are similar in that they both eliminate parasitic worms, but there is a difference. Mebendazole is approved for human consumption by the FDA, while fenbendazole is only approved for veterinary use and has not been approved for human use.

Mebendazole is the form that is approved for human use while fenbendazole is approved for veterinary use. The main difference is the cost. While most of the pre-clinical research uses mebendazole, probably because it is the FDA-approved-for-humans form of fenbendazole, virtually most of the self-treating clinical reports involve the use of fenbendazole.

Case No. 2 - 2024: Stage 4 Pancreatic Cancer

“My Cancer Story! I was diagnosed with stage 4 pancreatic cancer in August 2023, and without treatment, I had 3-6 months to sort out my affairs.

I began my fenbendazole protocol immediately.

I nearly quit up since my quality of life had deteriorated dramatically. But I started to feel better. Less nausea. I had gained some weight back! Increased energy. My scan in November 2023 indicated that this severe cancer had neither grown or spread. My cancer marker dropped from over 100,000 to 35,000. As of January 2024, my new marker number was 18k!!! My oncologist was just scratching his head, and a family member said he seemed bewildered! And no, I did not inform him about the fenben.”

I was terrified he’d drop me as a patient. I was quite appreciative for fenben and how it has helped me. I was feeling better and stronger. I had scans and bloodwork done in March, and my markers are now down to 6000. And the tumors were shrinking!!! Two weeks after my previous scan. I scanned again, and it returned NED.


This was my protocol:


Morning
  • Curcumin (600mg daily)
  • Zinc (50mg)
  • Milk thistle, As a food supplement, take 15 – 30 drops, 2-3 times daily in a little fruit juice or water. 7 days a week
  • Serrapeptase (120,00IU)
  • Fenbendazole (1000mg of Panacur C is advised to be taken seven days a week. It is recommended that it should be taken with a meal).
Night
  • Curcumin (600mg tablet per day are recommended
  • Berberine (600mg 2-3 times a day )
  • Quercetin (500mg 1/day)
  • Turkey Tail
  • Vitamin E (800mg for 7 days a week)
  • Fenbendazole (1000mg at night)
  • Ivermectin 12mg daily 5/7days a week
  • Limit sugar and processed food intake
  • Drank green tea often”

*My Take…

This is an excellent protocol.

**Note on pancreatic cancer marker (CA 19-9):

A CA 19-9 test measures the amount of a protein called CA 19-9 (cancer antigen 19-9) in a sample of your blood. CA 19-9 is a type of tumor marker. Tumor markers are substances made by cancer cells or by normal cells in response to cancer in your body. Healthy people can have small amounts of CA 19-9 in their blood. High levels of CA 19-9 are often a sign of pancreatic cancer. But high levels can also be a sign of other types of cancer or certain conditions that aren't cancer. For example, gallstones, pancreatitis and cirrhosis of the liver can cause high CA 19-9 levels.

Case No. 1 - 2023: Stage 4 Pancreatic Cancer (Last update: March, 2023)

My family member was diagnosed in stage 4 pancreatic cancer in August 2022. She was told it was very aggressive and without treatment she had 3-6 months and to get her affairs in order. She started 220 fenben immediately. She was very ill and hospitalized with sepsis and colitis from eating tainted peanut butter. She lost about 20 pounds. It took 2 months to start chemo, which made her very sick. We almost gave up because her quality of life had declined significantly. But she started feeling better. Less nausea. She has gained weight back! More energy.. Her latest scan showed this aggressive cancer has not grown or spread. Her cancer numbers or markers went from being over 100k down to 35k.

*** UPDATE: As of today, march 2nd, her new marker number is 18k!!) Her oncologist was just scratching his head.. my family member stated he looked confused! And no, she didn’t tell him about the fenben. We are afraid he would drop her as a patient.We are so very grateful for fenben and how it’s helped her. She is feeling better, stronger, and enjoying her family. I have never posted on here. But I wanted to give you some hope!

**UPDATE**She had scans and bloodwork done 2 weeks ago and we got the results today!! She is eating better and gaining weight.. Her markers are now down to 6000. AND THE TUMORS ARE SHRINKING!!! We are very grateful!!
