A new genetic test to gauge the aggressiveness of prostate cancer went on sale Wednesday.

The test analyzes multiple genes in a biopsy sample and gives a score for aggressiveness.

Similar tests are currently used for certain breast and colon cancers. Doctors say tests like these may help doctors decide how to treat the cancer.

Prostate tumors usually grow so slowly they will never threaten a man's life, but some prove fatal, and there is no reliable way now to tell which ones will.
