It is not clear what causes prostate cancer.

Doctors know that prostate cancer begins when cells in the prostate develop changes in their DNA. A cell’s DNA contains the instructions that tell a cell what to do. The changes tell the cells to grow and divide more rapidly than normal cells do. The abnormal cells continue living when other cells would die.

The accumulating abnormal cells form a tumor that can grow to invade nearby tissue. In time, some abnormal cells can break away and spread to other parts of the body.

DIAGNOSIS

  1. Prostate-specific antigen (PSA) test
  2. A doctor examines the prostate by inserting a gloved finger into your bottom called a Digital rectal examination (DRE)

COMPLICATIONS

Complications of prostate cancer and its treatments include:

  • Cancer that spreads (metastasizes). Prostate cancer can spread to nearby organs, such as your bladder, or travel through your bloodstream or lymphatic system to your bones or other organs. Prostate cancer that spreads to the bones can cause pain and broken bones. Once prostate cancer has spread to other areas of the body, it may still respond to treatment and may be controlled, but it’s unlikely to be cured.
  • Incontinence. Both prostate cancer and its treatment can cause urinary incontinence. Treatment for incontinence depends on the type you have, how severe it is, and the likelihood it will improve over time. Treatment options may include medications, catheters, and surgery.
  • Erectile dysfunction. Erectile dysfunction can result from prostate cancer or its treatment, including surgery, radiation, or hormone treatments. Medications, vacuum devices that assist in achieving an erection, and surgery are available to treat erectile dysfunction.
