Black wart-like dots around the nipple are considered to be Montgomery’s nodes. Montgomery’s nodules are sebaceous glands around the nipple. Normally Montgomery’s nodules are not obvious, but after pregnancy occurs in women, due to changes in hormone secretion and hormonal stimulation, Montgomery’s nodules appear as granular bumps distributed around the nipple in black or brown color, and are usually not accompanied by symptoms such as pain and itching. Montgomery’s nodes are a normal physiological change in women and generally do not require treatment. They will return to their normal nipple state after pregnancy and childbirth, so avoid scratching, snapping, digging, etc. with your hands. If the black dots on the nipple occur swelling, pain, pus and other changes, you need to use iodophor to do local disinfection, topical erythromycin ointment and other treatments. If the swelling, pain, etc. of montana nodules occur, and the symptoms cannot be relieved by the above treatments, it is recommended to go to the hospital in time for consultation and treatment.
