I was diagnosed in 2018, with a tiny Gleason 3+3 lesion. I flatly refused the radical treatments my doctor proposed. Last month's MRI showed that my cancer wasn't any different from 7 years ago.
Pr. Ablin , the discoverer of PSA has always vehemently opposed its use for screening, while he didn't deny that it was an excellent tool to monitor cancer treatment.
Using a marker that gives a large proportion of false positives, as well as some false negatives, seems preposterous if not driven by the lure of profit, sadly. And this is even more so our days where MP-MRI is readily available.
