Breast Cancer - Metaplastic

This section has been reviewed and approved by the Cancer.Net Editorial Board, 8/2010

Women with metaplastic carcinoma of the breast may experience the following symptoms. Sometimes, women with metaplastic carcinoma of the breast do not show any of these symptoms. Or, these symptoms may be caused by a medical condition that is not cancer. If you are concerned about a symptom on this list, please talk with your doctor.

Many breast cancers develop with no symptoms at all. Some tumors may be visible on a mammogram before symptoms develop. It is important for all women to be familiar with the appearance, feel, shape, and texture of their breasts in order to detect changes as soon as they occur.

  • New lumps (many women normally have lumpy breasts) or a thickening in the breast or under the arm
  • Nipple tenderness, discharge, or physical changes (such as a nipple turned inward or a persistent sore)
  • Skin irritation or changes, such as puckers, dimples, scaliness, or new creases
  • Warm, red, swollen breasts with a rash resembling the skin of an orange (called peau d'orange)
  • Pain in the breast (usually not a symptom of breast cancer, but should be reported to a doctor)
