Could a breast lump or change be a sign of cancer?

ANSWER

Although it's a hallmark symptom of breast cancer, most lumps aren't cancer. They're often cysts or noncancerous tumors.

Still, see your doctor right away if you find any new or changing growths in your breasts, just to make sure.

Also, get checked for any of these changes:

  • Redness or scaling of the skin over the breast
  • Breast pain
  • Nipple changes
  • Lumps under your arm
  • Fluid that isn't breast milk leaking from the nipple
