Janice, welcome to this site. There is one and only one way to tell if someone has prostate cancer, and that is by having a prostate biopsy.
PSA screening tests are not very "specific" for prostate cancer (PC); that is, the PSA test result might be elevated because of PC or it could be elevated because of other causes (also given by Tall Allen). This is a drawback of the currently available PSA test...but it's the best first-level screening test that we have today.
An elevated PSA result should be a "red flag" that someting is wrong which needs to be looked into. A prostate infection (prostatitis, which elevates PSA) can be dangerous and needs looking into & treatment. BPH (which elevates PSA) needs looking into & treatment. PC can be dangerous and needs looking into.
A urologist should examine the case circumstances to weed-out possible non-cancerous causes before proceeding to a biopsy. A course of anti-biotics is commonly given to eliminate possible infection, for example.
hope this helps...
