Opportunitiy, "There are no better markers to date."
You are extremely out of touch with what is going on. PSA is having problems because it detects TOO MANY cancers. If I remember correctly, for men over 60, about 59% in one study had slow growing prostate cancers. You do not want a test that will just indicate you have cancer cells. You need a test that will tell you if you have fast growing cancer cells. That is what will make RECAF a worthless test. You will in essence have a more worthless test than PSA and causing more problems that PSA ever caused.
There is no test out there that will tell you that you have a fast growing cancer but that is what is needed. That is why RECAF will never be a first line of diagnosis test. I do not think it will ever be a 2nd, 3rd or 4th either. It will just have a difficult time ever developing a market.
If you moved back more than 10 years ago when PSA was first being approved, there might have been a following for RECAF but not today. The medical community today realizes there is a lot more to curing cancer than just early detection.
BTW, you stated you had a medical degree. What is it?
