If your PSA is at all elevated get a biopsy. Don't let them scare you away from that. Done by a good doctor it hurts less than having a cavity filled. If you get a negative biopsy, great! If the PSA keeps rising, though, get another one. It's probably nothing. But you need to know.
Really, this could save your life. If there's cancer in there and you catch it early odds are very good you can be cured with minimal side effects. With every passing week your odds go down.
