Question - Wouldn't you want to know about any cancer in the prostate? Or, does this change the overall approach to prostate caner? Just tell me when its the bad one, and, disregard the rest.
Maybe, but today we can't do that well unless we do a lot of expensive and sometimes invasive testing. Plus the tests are applied evenly - some men get over tested and some under or never tested. Even then test results can be ambiguous and you risk level is somewhat subjective.
One problem is that when you use the word, "cancer," most people freak out and start yelling, "take it out, take it out." If we had the ability to tell people, "this is a benign tumor" or "this is aggressive cancer," with a high degree of accuracy in a simple blood test, then we'll have gone a long way towards ending over testing, over treatment and on to a path of appropriate treatment verses risk.
The other thing I found interesting in this article is the possibility of screen for men with low PSA who have aggressive PC. Rare, but it happens.
If this test does make into the mainstream it has the possibility of rendering PSA alone obsolete and ending that whole debate.
Personally, I am thinking of setting up a blood lab in my workshop so I can start offering this test. Just ignore the sawdust on the result sheets...
I'll be in the shop.
