Introduction
The main goal with this article is to provide as much clear information as possible for someone dealing with lung cancer. This article deals with the basis and practical approach to using Fenbendazole and Ivermectin for lung cancer.
In this article, we explore case studies involving ivermectin and
fenbendazole—unfiltered by traditional gatekeepers—and their potential role in
managing lung cancer. Could these repurposed drugs offer new hope for patients
seeking additional treatment options? Let’s take a closer look."
Fenbendazole and Ivermectin and Fenbendazole or Mebendazole Lung Cancer Case Series Compilation
We have compiled a list of ivermecin and fenbendazole or mebendazole for
lung cancer case reports below.
This compilation features several case reports involving the use of
ivermectin and/or fenbendazole for lung cancer.
Case 17: Japanese man with Stage 4 Lung Cancer (video link below)
- Fenbendazole
- Vitamin D
- CBD Oil
Stage 4 Lung Cancer can be very responsive to a combination of Ivermectin, Fenbendazole and CBD Oil.
— William Makis MD (@MakisMD) May 27, 2025
There are several published cases of 3-4cm lung tumors resolving with just CBD Oil applied under the tongue for a few months.
These gentlemen actually picked the two best… pic.twitter.com/yfKnSF5pMZ
Case 16: 53 year old USA man with Stage 4 NSCLC Lung Cancer
metastatic to lymph nodes and adrenals

Dr William Makis shared on X/Twitter in May 2025:
STORY: 53 year old man (USA) with Stage 4 NSCLC Lung Cancer with extensive metastases to mediastinal lymph nodes, adrenals, brain. Had been on Keytruda since April 2024 We started (end of Jan.2025):
PET Scan done just over 1 month later: - Ivermectin 1.5mg/kg/day
- Mebendazole 1000mg/day
“Interval near complete resolution of extensive hypermetabolic mediastinal and hilar adenopathy” “Interval resolution of previously demonstrated hypermetabolic adrenal metastases”.
"Interval" in this case is since the start of Ivermectin and Mebendazole, which the patient started in January.
My Take...
This is where Ivermectin, Fenbendazole and Mebendazole can really dramatically improve results. This combination, in addition to killing cancer cells, also acts as a chemosensitizer and radiosensitizer. Which means more cancer cells are killed once chemo is added, or radiation treatment takes place.
Case 15: 64 year old Canadian woman with Stage 4 NSCLC Lung Cancer with Brain metastases
We started in mid February 2025:
Case 14: 45-year-old UK woman with Stage 4 Non-Small Cell Lung Cancer
with lymph node, liver and adrenal metastases
Case 15: 64 year old Canadian woman with Stage 4 NSCLC Lung Cancer with Brain metastases
Case testimonial from Dr William Makis (X/Twitter) in April 2025:
IVERMECTIN and MEBENDAZOLE Testimonial - 64 year old Canadian woman with Stage 4 NSCLC Lung Cancer with Brain metastases has incredible response (up to 90% brain lesion shrinkage)! I always get asked about cancer in the brain. Well, there is hope there too!
IVERMECTIN and MEBENDAZOLE Testimonial - 64 year old Canadian woman with Stage 4 NSCLC Lung Cancer with Brain metastases has incredible response (up to 90% brain lesion shrinkage)! I always get asked about cancer in the brain. Well, there is hope there too!
STORY: 64 year old Canadian woman with Stage 4 NSCLC Lung Cancer with 20+ Brain metastases
- Ivermectin 1.5mg/kg/day
- Mebendazole 2000mg/day (yes, you read that correctly. Now you know why the clinical trials they did with Mebendazole at 200mg/day didn't work)
RESULTS after 2 months:
Consider: this is shrinkage of brain metastases after 2 months of Ivermectin and Mebendazole!!
- Lesion 1 - 16x13mm to 10x7mm = 80% shrinkage
- Lesion 2 - 16x15mm to 12x10mm = 65% shrinkage
- Lesion 3 - 13mm to 9mm = 67% shrinkage
- Lesion 4 - 13mm to 6mm = 90% shrinkage
- Lesion 5 - 8mm to 4mm = 88% shrinkage
From the patient:
"Thank you so much for your guidance and support, this is very encouraging and gives me hope for the future"

Case 12:
IVERMECTIN and FENBENDAZOLE Testimonial - 45 year old UK woman with
Stage 4 Non-Small Cell Lung Cancer with lymph node, liver and adrenal
metastases, has 75% of disease gone after 4 months!
Ready for a nice Stage 4 Lung Cancer story?
45 year old UK woman with Stage 4 NSCLC Lung Cancer with lymph node,
liver, and adrenal metastases.
In early September 2024 we started:
- Ivermectin 1 to 2 mg/kg/day (eventually built up to 96mg Ivermectin a day, or 1.5mg/kg)
- Fenbendazole 444mg a day
- CBD Oil 25mg a day
- Melatonin 120mg a day
Oncologist started Osimertinib (Tagrisso)
RESULTS (January 2025 PET/CT):
- Adrenal metastasis shrunk from 6cm to 3.6cm
- Lymph node metastases resolved
- Liver metastases resolved
- Oncologist estimated 75% of tumor burden had resolved.
The patient had some transient visual side effects with Ivermectin
which are typical in the beginning but they went away.
"Liver completely cleared up"
"Lymph lump in neck completely gone"
Case 13: Stage 4 Lung Cancer patient in India with
metastases to brain, liver and bones, sees dramatic recovery including
"complete resolution" of liver & bone mets! (Jan 2025
update)
"IVERMECTIN and FENBENDAZOLE Testimonial - Stage 4 Lung Cancer patient
in India with metastases to brain, liver and bones, sees dramatic
recovery including "complete resolution" of liver & bone mets!
An International story you're going to love!
Adarsh contacted me in early September 2024 about his dying father in
India who had Stage 4 Lung Cancer with metastases everywhere including
brain, liver, bones.
"doctors has given some months to live".
So I suggested an Ivermectin/Fenbendazole Protocol - something simple,
yet powerful:
- Ivermectin 1.5mg/kg/day
- Fenbendazole 444mg/day (I suggested up to 888mg)
RESULTS:
PET Scan of 27 November, 2024:
- complete metabolic resolution of liver and bone metastases (!)
- decrease in size and number of mediastinal lymph nodes
- decrease in size of brain metastases (!)
- decrease in lung lesion.

Case 10: IVERMECTIN and FENBENDAZOLE Testimonial - 40s
year old California Man with Stage 4 Lung Cancer (Jan 2025 update)
"IVERMECTIN and FENBENDAZOLE Testimonial - 40s year old California Man
with Stage 4 Lung Cancer (post three Pfizer COVID-19 Vaccines, Turbo
Cancer?) sees dramatic improvement in 3 months!
Another wonderful story for you:
40s year old California man (who had three Pfizer COVID-19 mRNA
Vaccines), was coughing for months, and was diagnosed with an unexpected
Stage 4 Lung Cancer (NSCLC) metastatic to numerous lymph nodes and
pleura, with a pleural effusion.
We started an aggressive protocol:
- Ivermectin 1mg/kg/day increasing slowly to 2mg/kg/day (high dose!)
- Fenbendazole 888mg/day
- Oncologist also started Tagrisso (Osimertinib)
3 Months Later:
- Primary lung tumor reduced in size from 3cm to 2cm.
- Pleural effusion resolved completely (!)
- Gained 15 pounds of weight from his lowest before he started the protocol. These are very significant improvements!"
Case 9: November 2024 - Ivermectin and Fenbendazole for stage 4 NSCLC Lung Cancer
40s year old Stage 4 Lung Cancer Patient in the UK In August 2024, we
started Ivermectin 1mg/kg/day and Fenbendazole 444mg/day 6 days on 1 day
off
There were some transient visual effects from Ivermectin to overcome in
the first few weeks (see messages) But they went away after a few
days!
And less need for strong pain medications! 3 month Follow-up Report:
“Cancer is stable and all lesions / tumours have shrunk”
“biggest shrink of all was the one above adrenal gland which has gone from
6cm to 3.6cm!”
“spots on the left lung and liver were so small they were too small to
measure”
My Take… It is wonderful to see results like this after only 3 months!
Sometimes there are some minor growing pains in the beginning - some
transient side effects to overcome (like the visual side effects of
ivermectin), but once you overcome them, it’s smooth sailing! In this case
they lasted about 10 days and then they were gone.
And yes, we did push to get to Ivermectin 2mg/kg/day (substantial dose)
and Fenbendazole 888mg/day (moderate dose). Can you imagine a Stage 4 Lung
6cm adrenal metastasis shrinking to 3.6cm and all other lesions shrinking,
some disappearing or becoming too small to measure? In just 3 months? Not
bad for horse medicine!
I'm not ready to post exact details, but my wife's Stage 4 lung cancer is
seemingly going away. Main tumor has gone from 6.4 to 2.6. Lymph spits all
but gone. Lower lung spot gone. She has been on a targeted gene therapy
drug and is using fenbendazole, curcumin, and Vitamin E.
Case 8: November 2024
Case sharing by Gerard Donald (X/Twitter):
Case 7: October 2024 - Ivermectin and Fenbendazole for stage 4 Lung
Cancer
One of my cancer patients is a woman in her 70s with Stage 4 Lung Cancer
with multiple liver metastases. “Less than 7 weeks after initiating the
protocol”
Primary Lung lesion LLL 2.9cm to 2.1cm (28% decrease)
Liver at porta hepatis 5.3cm to 1.6cm (70% decrease)
Right hepatic lobe inferiorly, 2.4cm to 1.0cm (58% decrease)
Right hepatic lobe, 2.1cm to 0.8cm (62% decrease)
"I wholly believe, as does my wife, that the protocol is doing the heavy lifting".
Condition: Stage 2 Adenocarcinoma in his upper right lung lobe
In July of 2018, my husband received his first cancer diagnosis. Stage 2 Adenocarcinoma in his upper right lung lobe. Mutations tested. Lobe was removed
July 23, 2018, and he was put on active surveillance, no treatment.
On 11/14/2018, he received his second diagnosis, prostate cancer, adenocarcinoma with metastasis, stage 4, and Gleason score 9. Prostate was removed,followed by 7 weeks of radiation, and put on ADT therapy (Lupron and Xtandi), no chemo. Mutations tested, not favorable, and very aggressive. He is a rare case where cancer didn’t show in blood or any scans. To this day, it still doesn’t. We can only monitor by symptoms.
He started to progress in symptoms in June of 2022. August of 2022, diagnosed with a 2nd lung cancer, stage 4 adenocarcinoma. Mutation testing repeated, this time, it showed similar mutations as 1st lung cancer, but also some slightly different ones that led them to believe it was a different cancer.
He began treatment on 01/09/2023. We were not given any hope, and they said mutations were not in his favor and that treatment was highly unlikely to do anything, but they offered it anyways saying it would buy him time. They made it very clear he did not have the mutations they were hoping to see, they were hoping it was a mutation that responds favorably to treatment,and he didnt have those.
It didn’t make sense, in 1 sentence they stated it wasn’t likely to work, but yet it could buy him time?? It is his journey, and he decided to try. 2 chemo drugs, and I immunotherapy for 4 treatments spaced 3 weeks apart. Then they dropped 1 chemo and said he would stay on double treatment for up to 2 years, then they would drop to just immunotherapy. He stayed on double for 7 treatments. But his body was worn out. They decided 1 more treatment, and if scans looked good, they would drop the other chemo. But he got sick just before the last double treatment was supposed to happen. It has delayed his scan as well. But it is a viral thing, not cancer related, as far as we know.
Let’s get to the good stuff though… People started sending me messages, LOTS of people, asking me if I’d heard of the Fenben Protocol. I started getting these messages in August of 2022, right after his biopsy confirmed a new occurrence. To be honest, I ignored the messages until I got 2 in 1 day in November. I decided ok, I’m going to check this out. I joined the group on December 16th, 2022 and I started tearing into the files. And I started researching, and research led me to a medical sight that leaned very favorably in Fenbens direction. We discussed as to whether to bring it up to oncology, but they had made it clear in the beginning that if we choose to do natural, they would not treat him, so we kept our mouths shut.
He started the protocol at the end of February. His scans on 12/22 and 02/23 showed new masses had grown since the scan in July of 22. But by the next scan on 04/06/2023 many of the masses were still present, but stopped growing. But the masses in his pleura (which is what deemed him terminal) were almost gone! Let me note right here, that by this time, his prostate symptom progression stopped, and then the symptoms resolved.
Next scan on 05/30/2023, pleura masses are now unremarkable, and the other scattered masses still haven’t grown any.
Next scan on 07/30/2023, pleura isn’t even discussed, no remarks! Dr says they can’t see anything there at all! And the other masses remain unchanged, no growth! Whether we simply bought him time, or he’s healing, we will take it! But our hope is restored. He’s not in pain and he’s still his ornery self. And we remain grateful to the community for the knowledge and support.
Case 5: July, 2022
I have stage 4 Adenocarcinoma of the lungs…doctor told me it’s not curable. I’m 44 with two teenagers so I don’t want to hear that kind of news. Anyway, I was diagnosed in December and by January I received chemotherapy. A friend told me about Fenbendazole and I started it immediately. I am now on chemotherapy, immunotherapy, and Fenbendazole. After 4 treatments…I had a PET Scan….the scan was remarkable. Many subcentimeters nodules resolved, the two large masses are shrinking, no enlarged lymph nodes in the hilar and mediastinal region. No new growth! I’m hoping this is a good sign.
*Using Fenbendazole 220mg day and night, chemo taxol/Carbo, and Keytruda since January.
Plan to start Vitamin E, Milk thistle for liver, and Turmeric/Curcumin this week.
Case 4: July, 2022
They gave my husband 18 months to live in 2019, from having SCLC with no primary tumor. Mets everywhere. He has been doing Joe Tippens protocol before he even started chemo. Chemo didn’t work and he is now on Opdivo infusions once a month. We found out he had cancer from 3 fractures on his vertebrae. Went to his brain and that’s all gone also. Thank you Joe!! Praise the dear Lord!!
DATE OF EXAM: May 5 2022 10:17AM
AKP 0063 – NM PET/CT SKULL-THIGH SUBQ / ACCESSION # 130564079
PROCEDURE REASON: Malignant neoplasm of unspecified part of unspecified
bronchus or lung (HCC)
Case 3: March, 2022
In 2020, I was diagnosed with stage 4 lung carcinoma. The Oncologist found a big tumor growing on my left lung along with a massive tumor inside my chest cavity so big that it started constricting my heart arteries.
They started me with radiation right away followed by weeks of intensive chemotherapy, and I got so sick that they had to lower the doses and frequency to half of what they originally had me on.
Case 2: November, 2021
About three months ago my wife was diagnosed with metastatic cancer on her lungs and gave her a 3 months prognosis. She had five aggressively growing nodules.
A friend reached out to me about the fenbendazole protocol that she was following at the time. Today my wife came back from a visit to the Oncologist with test results showing a major improvement on the growths – only two small nodules were found! This is truly a miracle and a blessing!
Case 1: Small Cell Lung Cancer (SCLC) with Joe Tippens Cancer Protocol
(2017)
Joe Tippens had been initially diagnosed with small cell lung cancer. The cancer later spread to his neck, right lung, stomach, liver, bladder, pancreas and tail bone. Like the scientist from Merk Animal Hospital, Joe was told he only had three months to live. In 2017, after hearing the story of the scientist who treated her cancer with a canine drug, Joe decided he was going to do the same. However, in addition to taking the fenbendazole, Joe added his own ingredients to the regimen (curcumin, CBD oil, and vitamin E), thus creating the Joe Tippens Cancer Protocol.
This case series is part of the 'Ivermectin, Fenbendazole, and Mebendazole Cancer Case Series'.
Conclusion and Key Takeaway
Keep in mind that these references are based on case reports, which offer preliminary evidence. Critics may dismiss them as pseudoscience or low-quality data or even misinformation. However, these testimonials could represent just the tip of the iceberg—an emerging frontier that science is only beginning to explore.
For a more comprehensive understanding, it's worth looking into additional research studies and clinical trials. As always, consult with your healthcare provider(s) before making any treatment decisions, as close monitoring and personalised care are essential.

Our aim here isn't to replace your doctors' advice. It is intended as a sharing of knowledge and information. Do take note that cancer is a continuous struggle between the immune system and the cancer cells. Cancer treatments are meant to assist the immune system in this battle. Any potential treatment—whether conventional or complementary—must be evaluated on a case-by-case basis, with careful consideration of the benefit-risk ratio to ensure both safety and efficacy.
- The case reports presented reflect the real-life experiences and opinions of other readers or users of the website.

We do not claim, and you should not assume, that all other readers/users will have the same experiences. Do you own research, consult with relevant medical professionals before attempting to self-treat for any condition.
- Cancer treatment should be part of a multi-modal approach in order to provide the best possible outcome. Diet and lifestyle changes are meant to run alongside conventional treatment. They are complementary, not alternative.
- Cancer care is a team effort with the patient at the centre. Care should be supervised and coordinated by a primary healthcare provider. Patients with cancer should consult with their regular oncologist as well as an integrative provider/oncologist, in addition to their primary care provider and the supporting nurses, dieticians and other allied healthcare professionals.
- While the term 'alternative' might imply opposition to conventional oncology, we prefer 'complementary,' 'integrated,' or 'holistic.' These terms better reflect the role of these strategies as part of a personalized value-added menu of strategies, ensuring the most effective and safe solutions for patients.
- Integrating a repurposed drug doesn't mean rejecting modern medicine — It enhances it and offers a more comprehensive approach to wellness and healing. By combining conventional cancer management with root-cause resolution, this model creates a path to sustained recovery and resilience.
