Symptoms of Breast Cancer

Usually, the earliest stages of breast cancer do not cause pain. In fact, when breast cancer first develops, there may be no symptoms at all.

A lump or thickening in the breast or under the arm is one of the most common signs of breast cancer. To detect breast cancer, watch for the following:

  • a lump or thickening in or near the breast or in the underarm area

  • a clear or bloody discharge from the nipple

  • inverted nipple

  • a change in the color or feel of the skin of the breast, areola or nipple (dimpled, puckered or scaly)

  • a change in the size or shape of the breast

  • a change in the normal balance of your breasts, such as swelling or one being higher than the other.


If you have a breast lump or notice any of these other changes, see a provider who is experienced in breast examination right away.
