My Urologist says not to worry about it that it isn't cancer. every other doctor I've talked to said the same. My urolgist checked my prostate and says it isn't cancer. Now for the big kicker, this has been going on since last July, so it has been over a year and there is blood in the semen every time. Is it time to get a different doctor. What test can be done to find out why I still have blood in the semen. the color is like a rust color.
