You claimed that "polyp will very likely eventually become cancer". I don't think this is true, in general, for polyps even though some might become cancerous. The paper you provided is pretty dense, but it didn't see to me as though it is saying that polyps generally become cancerous.
It's an internet forum, I didn't claim anything. And your doctor isn't going to first biopsy just a little bit of a polyp to determine if it's the "bad" kind, he's going to remove all of it.
It's annoying pedantry, a distinction without a difference.
Oh FFS. The difference between polyps very likely becoming cancer and some polyps maybe becoming cancer is not pedantry. And it probably wouldn't be as annoying to you if you just said that you didn't know instead of attempting to dig deeper by providing a source that you either didn't read or didn't understand.
