The nipple area is usually subject to tiny bumpy changes, and the appearance of small bumps can sometimes be a physiological change, but can also be a problem caused by a pathological state. 1. Montgomery’s nodules are a type of bumps that are most commonly found around the nipple or areola tissue and occur mainly during the pregnancy cycle or during breastfeeding. The main purpose of these bumps is to produce some lubricating fluid that facilitates breastfeeding for the little one and protects the mother’s breasts. This is a relatively common physiological phenomenon. 2. If the bumps in the nipple area are red and swollen in appearance, there is more obvious pain. You need to consider if there is a combination of inflammation. Inflammation usually leads to uncomfortable manifestations such as redness and pain in the skin. In addition, breast fibroids, which can also grow in this area, are benign breast tumors that generally do not pose a serious risk to the body. Intraductal papilloma is a not uncommon disease that presents with small bumps on the nipples and sometimes bloody or other colored discharge when the nipples are squeezed, which is the main characteristic of this disease. The main treatment for this disease is surgery. Therefore, when small bumps appear next to the nipples, it is still necessary to identify them specifically to exclude some diseases.
