Cancer: Warning Signs

There usually are no signs or symptoms when cancer is in a very early stage. Sometimes early symptoms do not seem like anything serious. Learning what to look for can lead to early detection. Early detection of a cancer often greatly increases the chances of a cure.

The American Cancer Society has identified the main warning signs of cancer:

  • changes in the way a wart or mole looks
  • a sore that does not heal
  • a lump in the breast or other parts of the body, or discharge from the breast
  • coughing or hoarseness that does not go away
  • a change in bowel or bladder habits
  • unusual bleeding or discharge from any part of the body
  • indigestion that does not go away
  • trouble swallowing
  • tiredness (fatigue) that lasts day after day for a week or longer.

You should have a checkup soon if you have any of these warning signs. Having one of these warning signs does not mean you have cancer. However, if you do have cancer, early treatment greatly increases your chances of a cure.

To learn more about the warning signs of cancer, call your local chapter of the American Cancer Society, or call (800) ACS-2345 or the National Cancer Institute at (800) 4-CANCER.
