There are no hard and fast rules, and even the experts don't always agree on the best course of action. What happens next depends on whether or not you have any symptoms, your personal risk of prostate cancer, how high the PSA level is, and your age (the older you are, the higher your PSA level is likely to be whether or not you have prostate cancer).
As a rough guide, there are three main options after a PSA test:
* PSA not raised: Highly unlikely to have cancer. No further action.
* PSA slightly raised: Probably not cancer, but might need to repeat the test.
* PSA definitely raised: Probably need a biopsy to find out if you have prostate cancer.
