A Look at Prostate Cancer Prostate cancer starts in the prostate gland, which is found only in men. Most often, the cancer is found in men over age 50. More than 80 percent of all prostate cancers are diagnosed in men over the age of 65.
Prostate cancer is the most common type of cancer found in American men, other than skin cancer.
The American Cancer Society predicts that there will be about 180,400 new cases of prostate cancer in this country this year. Certain risk factors are considered to increase risk of having prostate cancer. Because its exact cause is not known, preventing it is also somewhat of a mystery. However, the American Cancer Society recommends a diet low in animal fat and high in vegetables, fruits and grains, which may also lower the risk for some other cancers. Tomatoes, grapefruit and watermelon are rich in a substance that helps prevent damage to DNA and may help lower prostate cancer risk.
