Can biopsies spread cancer cells?

Yes, certainly. There is published literature on this. Practically, however, is this a problem? Not in the vast majority of cases. The risk remains very low. Grok will tell you < 1%. That sounds about right. Your immune system will eliminate those escaped cancer cells. That's why you rarely see cases going from Stage 1 to Stage 4 post biopsy. Thousands of biopsies are done every day and I honestly don't recall more than a handful of bizarre cancer progressions.

However, if you have an aggressive cancer like pancreatic, kidney, liver (or Turbo Cancer) or an impaired immune system, your risk of this being a problem increases. So you have to weigh the risks vs benefit, like any medical procedure. Biopsies don't cause cancer spread in the vast majority of cases. HOWEVER... This is where I will blow your mind... How do tumors metastasize? One of the mechanisms is via matrix metalloproteinases, enzymes that detach tumor cells and allow them to metastasize. Guess what blocks matrix metalloproteinases? IVERMECTIN. You're welcome. From GROK: Inhibition of MMPs: There is some evidence suggesting that ivermectin can inhibit the activity of matrix metalloproteinases. Specifically: "Ivermectin and Tumor Metastasis: A study published in the National Library of Medicine (PMC) found that ivermectin could inhibit tumor metastasis in colorectal and breast cancer models by regulating pathways that also involve the expression of MMPs. The study noted that ivermectin decreased the levels of MMP-9, which is associated with cancer cell migration and invasion"
