Prostatitis is an inflammation of the prostate, a gland located below the bladder in men. The prostate is about the size of a walnut. It produces a whitish, viscous fluid that stimulates the movement of sperm. This liquid is part of the seminal fluid which also nourishes the sperm.
Some studies have suggested that prostatitis (inflammation of the prostate gland) may be associated with an increased risk of prostate cancer, although other studies have found no such association. Inflammation is often seen in samples of prostate tissue that also contain cancer. The association between the two is not clear, and is an active area of research.
