Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast. It is estimated 1 in every 7 American women will develop breast cancer in their lifetime. Two hundred and twenty thousand American women will develop breast cancer this year.

Breast Cancer Symptoms

Reported breast cancer symptoms include:
  • discharge from the nipple(clear or bloody)
  • persistent tenderness of the breast
  • pain in the nipple
  • swelling or mass in the armpit (lymph nodes)
  • inverted or scaly nipples
  • a lump that can be felt, no matter how small
  • swelling of the breast


Sometimes there are no symptoms of breast cancer when it is in the early stages. If you notice a lump, or are experiencing anything unusual, you must report the symptoms to your doctor as soon as possible. Performing a monthly self breast exam is the one of the best ways to notice any changes in your breasts.
