Your point is correct but as Brian pointed out, exposure to HPV doesn't prove anything about a cancer tumor. Although I used the qualifier "relevant" in my comment about blood tests not telling whether a cancer tumor is HPV or not, it would have been more accurate to use "probative". As I posted in another thread,the CDC stats 4 out of 5 women had HPV by age 50 so their blood tests would show HPV exposure but thank God 80% of women don't get oral cancer. I just wanted to be sure that Anita knew not to let her doctors try to pawn off a meaningless blood test instead of a meaningful HPV test on Clark's tumor. This cancer pretty much destroyed any trust I had about doctors' knowledge about HPV. As always, you keep me honest and accurate. Thanks
