Prostate cancer is cancer that occurs in the prostate. The prostate is a small walnut-shaped gland in men that produces the seminal fluid that nourishes and transports sperm.
Prostate cancer is one of the most common types of cancer in men. Usually, it grows slowly and is initially confined to the prostate gland, where it may not cause serious harm. However, while some types of prostate cancer grow slowly and may need minimal or even no treatment, other types are aggressive and can spread quickly.
Symptoms
Prostate cancer may cause no signs or symptoms in its early stages. Prostate cancer that's more advanced may cause signs and symptoms, such as:
Trouble urinating
Decreased force in the stream of urine
Blood in semen
Discomfort in the pelvic area
Bone pain
Erectile dysfunction
When to see a doctor
Make an appointment with your doctor if you have any signs or symptoms that worry you.
