Prostate Cancer

Description

Prostate cancer is a relatively common type of cancer affecting the small walnut-shaped prostate gland located near the base of the bladder and found only in men. The gland surrounds the upper part of the urethra, the tube that leads from the bladder to the penis. In more advanced stages of the disease the tumour may spread and eventually be carried (metastasise) to other areas of the body.

In the UK there are about 30,000 new cases of prostate cancer each year. It is rare in men under 45 and quite common in men over 80. However, in older men the cancer is often small, restricted to the prostate and without symptom.

Often, the first symptom of prostate cancer is difficulty in urination, as the growing tumour constricts the urethra. Frequent urination (especially at night); a weak or interrupted urine stream; pain or burning upon urination or ejaculation; pus or blood in urine or semen; and discomfort in the lower back, pelvis, or upper thighs, are also symptoms of the disease. Other conditions, such as urinary-tract infections, benign enlargement of the prostate (benign prostatic hypertrophy or BPH), a servious infection of the prostate gland (acute prostatitis)and sexually transmitted diseases can also cause some of these symptoms. A doctor is best able to evaluate your symptoms and request the tests necessary to make a diagnosis.
