I had 43 days of prostate cancer radiation about 5-6 years ago. My PSA becgan to rise in summer of 2014. Suddenly it went from 5 to 20 in 4 months, only to drop a bit the next week. My doctor suggets Leuprolide which is administered every 6 months by a shot. I’ve read many bad side affects(swelling of feel and legs, visual changes, hot flashes and generally lower testrosterone levels). Have others had this problem? I’m wondering if I should wait a month and have the PSA drawn again?.
