I was diagnosed with an elevated level in my prostrate. The doctor suggested that we test again soon, but this time refrain from any sexual activity for two weeks. The second series of test were in the normal range. Point being: Don't freak out, talk to your doctor. 

Prostate cancer 

Prostate cancer is cancer that occurs in a man's prostate — a small walnut-shaped gland that produces the seminal fluid that nourishes and transports sperm.

Prostate cancer is one of the most common types of cancer in men. Prostate cancer usually grows slowly and initially remains confined to the prostate gland, where it may not cause serious harm. While some types of prostate cancer grow slowly and may need minimal or no treatment, other types are aggressive and can spread quickly.

Prostate cancer that is detected early — when it's still confined to the prostate gland — has a better chance of successful treatment.
