Hi, new user here.
I was on propecia for 2 1/2 years and have recently experienced a lump within the left side of my chest. I told the doctor about this and he said it was due to the tablets, and that I should stop using propecia. After I stopped using propecia in April of this year, the lump has practically gone with only slight swelling. Now my doctor has booked me in for a blood test to check my hormone levels just to clarify whats going on. So if this is a direct result from propecia then I would say no, you are not pretty much golden for the rest of your life. What I would say is that if this lump has been forming since I started propecia (but I only noticed it a couple of months ago), which has taken 2 1/2 years, then for it to disappear, it has taken only about 3 months, which seems abit weird.
