Sore Nipples while Breastfeeding Baby

4. A Sign of Something Else

Chronic nipple pain can be a sign of a new pregnancy. If your pain lasts well after a feeding, you may want to take a pregnancy test. There are also some women who worry that nipple pain is associated with breast cancer, but this is extremely rare. "Pain is usually a late symptom of breast cancer and there would be other signs present," says Newman. There is a rare cancer known as inflammatory breast cancer than can look like an infection. If your symptoms are isolated to one breast and do not clear up with regular treatment, you should see a doctor as a precaution.
