I believe PSA screening at 40 if risk factors, in the family etc. Asked for mine at that time. It is contentious in PCa too. But it's more complicated in that palpation and scans are pretty marginal tools at early stage PCa. PSA can bounce around due to a variety of benign factors. And yes..typically slower growing than BC. Typically being the operative word. My Dad was told he was "cured"..until he nearly bled to death and they found it in his bladder. (a fun discussion.)
The PSA does remind me that in delving into BC treatments, I occassionally come across mention of markers that are only present in cancer patients...I mean beyond the typical tumor markers...or serum Her2. Seems like a blood sample panel oriented towards cancer detection might be a good adjunct to imaging and exam. Oh..but it might make people anxious.
