I have never once argued that NO cancers are caused by viruses, only that MOST cancers are not caused by viruses - which, despite all the studies and posts you refer to, is the opinion shared by the vast majority of people inside and outside mainstream medicine who deal with cancer.
Other than that, my only response to your post is this: If you want to debate cancer beyond a couple of posts where we set forth what our beliefs and positions are, we can do so in the Cancer Debate forum and not here in the support forum.
