Prostate cancer can grow slowly or very quickly. Most prostate cancer is slow-growing to start with and may never cause any symptoms or problems in a man's lifetime. However, some men will have cancer that is more aggressive or 'high risk.' This needs treatment to help prevent or delay it spreading outside the prostate gland.
If a man does have symptoms, such as problems urinating, they might be mild and happen over many years. For some men the first noticeable symptoms are from prostate cancer which has spread to their bones. If this happens, you may notice pain in your back, hips or pelvis that was not there before. These symptoms could be caused by other problems such as general aches and pains or arthritis, but it is still a good idea to get them checked out by your GP if you are worried.
Most men with early prostate cancer do not have any symptoms.
