Breast cancer does not always cause symptoms. The appearance of symptoms will depend on factors like the type, size, and location of the cancer.

If you experience any of these symptoms, do not assume it is due to cancer. Most of these symptoms may be caused by other, less serious health conditions, such as a breast cyst. If you have any of these symptoms, call your doctor for a diagnosis. Early detection and treatment can improve outcomes for both conditions.

Breast Changes

Early breast cancer usually does not cause physical pain, and symptoms may not initially be noticeable. The most common symptom is a painless lump or thickening in or near the breast, or in the underarm area. In some cases, the lump or thickening may cause pain. If the lump stops growing or shrinks, it does not mean the problem has gone away. Any changes in the breast should be reported to your doctor.

Other changes to be aware of include:

  • A change in the shape or size of the breast
  • Nipple discharge or tenderness
  • Inverted nipple
  • Ridges or pitting of the breast (resembling the skin of an orange)
  • A change in the way the skin of the breast, nipple, or areola (dark area surrounding the nipple), looks or feels (warm, swollen, red, or scaly)
  • A sore or ulcer on the breast that does not heal
