Women with breast cancer may experience the following symptoms. Sometimes, women with breast cancer 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.

However, most women who develop breast cancer have no signs or symptoms. The signs and symptoms to look for include:

• 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)
