What does it mean if there is a white spot on the nipple during breastfeeding?

Under normal circumstances, a white spot on the nipple during lactation may be related to milk residue, blocked mammary ducts, or nipple ulcers. Specific details are as follows:

1. Milk Residue

Lactating women who produce abundant milk may experience spontaneous milk leakage. After the moisture in the leaked milk evaporates, it can form a substance resembling fat granules. This is a normal phenomenon. It is recommended that lactating women gently wipe the area with a warm towel and keep the breasts clean and dry. Usually, no special treatment is required.

2. Blocked Mammary Ducts

During lactation, sebaceous glands in the breast may secrete excessive substances, which could easily lead to blocked mammary ducts, manifesting as localized white spots. Lactating women are advised to frequently clean the breasts to remove excess secretions. If necessary, a breast pump can be used to maintain duct patency.

3. Nipple Ulcer

Nipple ulcer refers to an ulcer formed on the nipple and surrounding tissues, possibly caused by nipple fissures, which may result in a white spot on the nipple. Lactating women should adjust their breastfeeding techniques to promote natural healing of the ulcer. If the ulcer persists for a prolonged period and bleeding occurs, breastfeeding should be temporarily stopped to avoid further irritation. Medications such as erythromycin ointment or anti-inflammatory tissue-regenerating ointment may be applied as directed by a physician to promote healing, after which breastfeeding can resume.

In addition, white spots may also be associated with other conditions such as folliculitis, sebaceous cysts, mastitis, or even breast cancer. Individuals experiencing discomfort should seek timely medical attention and receive standardized treatment under a doctor's guidance to facilitate recovery.
