Does radiation therapy do any good for an asymptomatic Grade IV prostate cancer patient

Stage IV   prostate cancers have already spread to the bladder, rectum, lymph nodes, or distant organs such as the bones. Doctors don't usually consider this  prostate cancer to be curable.

Treatment options may include:

• Hormone therapy
• External beam radiation plus hormone therapy (in selected cases)
• Surgery (TURP) to relieve symptoms such as bleeding or urinary obstruction
• Watchful waiting for older men whose cancer is causing no symptoms or for those who have another serious illness
