What Are the Symptoms of Breast Cancer?

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.
