Fiction. Lumps in the breast or underarm area aren’t the only symptoms that should raise an eyebrow. Changes in the size, shape or feel of your breast or nipple are also warning signs. So are swollen or painful breasts; thick, irritated or dimpled skin on the breast; scaly, red, painful or retracted nipples; and nipple discharge. In inflammatory breast cancer (IBC), a rare but aggressive type of breast cancer, redness or swelling of the breast might be the only symptom. If you experience any of these changes that aren’t a normal part of your menstrual cycle, see your doctor.
