    Colorectal Cancer, Metastatic or Recurrent - Cause

    The exact cause of colorectal cancer is not known. Most cases start as small growths, or polyps camera.gif, inside the intestine.

    Metastatic and recurrent colorectal cancer is caused when the cancer spreads or comes back, even years after treatment. Sometimes cancer cells are too small to be found and removed. They keep growing and cause problems later.
