During pregnancy there may appear small nodules on the breast in the area of nipple and areola – they are modified sebaceous glands. They are called Montgomery’s nodules and persist for a period of lactation.

Montgomery glands are so named because of the name of the Irish obstetrician Feterstouna William Montgomery, who first described the data of the structure. They perform a very important function – they secrete special substances that protect the breast from an infection and inflammation during breast feeding. After completion of the feeding period, these glands disappear by themselves.
