What is Prostate Cancer?

Cancer is a disease in which cells in your body grow out of control. Prostate cancer forms in the tissues of the prostate, a small walnut-shaped gland in the male reproductive system found below the bladder and in front of the rectum.


While the prostate contains several types of cells, almost all prostate cancers develop from the gland cells. Gland cells are the cells that develop the prostate fluid that is added to semen. Cancer that originates in gland cells is called adenocarcinoma. 

While some prostate cancers may grow quickly, in most cases this cancer is relatively slow-growing. In fact, most men diagnosed with the disease will not die from it. And early detection leads to an even better chance of successful treatment.

Not all prostate cancers are the same. Once diagnosed, it’s important to determine if the cancer is aggressive and needs active treatment, or if it is not aggressive and can be carefully monitored with active surveillance instead.
