Sure, absence of evidence is not evidence of absence. But these PCAWG results have been discussed to death since they were published, and its pretty sound science.

You could also take the bottom-up approach of asking what DOES cause certain cancers. That's a whole other discussion.

Considering all this, if you still have doubts that "viruses do not cause the majority of cancers", I think you will likely be skeptical about pretty much all of biology.

i do think flawed studies are more common than people realize (e.g., lung cancer one linked above, ebv ones referenced).

i wouldn’t say i’m skeptical.

more willing to say “unsure” until the underlying methods and logic have been validated.

based on personal anecdotes only, scientists seem too rushed and overworked, forced by our broken system to cite without verifying logic or methods first.

to be honest, part of me hopes you are right and all the virus science is sound. it would save me a lot of time and money.

thanks for sharing your thoughts and providing resources to check out.
