First, check yourself out in the mirror and ask yourself these questions:

• Do my breasts look the same?
• Is one larger or smaller than the other?
• Are my nipples the same shape?
• Are the veins more noticeable on one breast than the other?
• Is there any dimpling or puckering of the skin, bruises or bulges?
• Is there a lump, hard knot, or thickening of the skin?

Other changes that you should watch for:

• Swelling, warmth, redness, or darkening
• Itchy, scaly sore, or rash on the nipple
• Pulling in of your nipple or other parts
• Nipple discharge that starts suddenly
• New pain in one spot that does not go away

If you notice any changes or feel pain, call your doctor and schedule an appointment.
