Breast Cancer Signs and Symptoms


The signs and symptoms of breast cancer include:
  • A lump or thickening in or near the breast or in the underarm that persists through the menstrual cycle.
  • A mass or lump, which may feel as small as a pea.
  • A change in the size, shape, or contour of the breast.
  • A blood-stained or clear fluid discharge from the nipple.
  • A change in the feel or appearance of the skin on the breast or nipple (dimpled, puckered, scaly, or inflamed).
  • Redness of the skin on the breast or nipple.
  • An area that is distinctly different from any other area on either breast.
  • A marble-like hardened area under the skin.

These changes may be found during a breast self-exam.
Medical organizations don't agree on the recommendation for breast self-exams, which is an option for women starting in their 20s. Doctors should discuss the benefits and limitations of breast self-exam with their patients.
