In the United States, kidney cancer accounts for approximately 3% of all adult cancers. According to the American Cancer Society, about 32,000 new cases are diagnosed and about 12,000 people die from the disease annually. Kidney cancer occurs most often in people between the ages of 50 and 70, and affects men almost twice as often as women. There is a trend to move away from more toxic treatments that have fewer side effects, like oral medications now being used. Other forms of treatment continue to make an impact on this disease.
