Prostate cancer is usually a very slow growing cancer, often causing no symptoms until it is in an advanced stage. Most men with prostate cancer die of other causes, and many never know that they have the disease. But once prostate cancer begins to grow quickly or spreads outside the prostate, it is dangerous.
Prostate cancer in its early stages (when it’s only found in the prostate gland) can be treated with very good chances for survival. Fortunately, about 85% of American men with prostate cancer are diagnosed in an early stage of the disease.
