I've been taking propecia for years - probably close to 12 years - for hair loss. It seems to have worked and I didn't really lose more.
Anyhow - as you may know I've now have a dx @ 49 years old with G9 (4+5) in one core (10% to 40% involved, depending on pathology report) out of 13 samples - the rest were benign. My PSA is 3.56 (yep, low, but I'm sure that's due to the propecia).
So I've read a lot about the studies around finasteride and the ups and downs, first they said it causes high grade pc, then they said it doesn't.
From what I'm understanding, and I could be way off, due to the much smaller prostate from the propecia, it can make the biopsy cells look more aggressive - something about them being nests of cells tightly together, where as in a normal prostate they would be more spread out and not as aggressive looking?
I'm keeping my fingers crossed that this is all found early - they had to do an MRI to even find where to target the biopsy since I'd already had one come back negative last year. They also say it's in the middle, so I'm hoping for it to be contained. The only item I'm really worried about is that it's a 9 and chances for it coming back after surgery are high. After reading more about finasteride, I guess I wonder if it's really a 9?
Thanks - it's great to have somewhere to ask
