You never heard of CancerConnect? They are authoritative, up-to-dare in medical news, cancer, on-line communities, linking studies, abstracts, and believe are partnered with Dana-Farber in the on-line communities. I never seen any misinformation nor would I post it, if I thought so, and much of the info in this link is common knowledge, written elsewhere by other authoritative sites who just copy and paste each other. If I could, I would post OCF, but I have a hard time with doing that.
