Cells divide in an orderly, controlled way to produce more cells when more cells are needed in the body. When cells divide in an abnormal, uncontrolled way, they can form either a benign or malignant growth. Benign growth is not cancerous. More than half the men in the U.S. who are between 60 and 70 years old have symptoms of BPH . With benign growth, the cells do not spread to other parts of the body.
Malignant growth is cancerous.
Cancer cells can spread to nearby healthy cells and destroy them. The cancerous cells can also invade other parts of the body. Cancerous cells in the prostate can spread to the lymph glands which are located nearby. The cancer can also spread to the bones, liver, bladder, and rectum. African American men have the highest rate of prostate cancer in the world.
