Small granules next to the nipples in women are considered to be the following: first, a nodule called Montgomery’s gland, which in most cases is proliferated during pregnancy due to the influence of progesterone levels, as well as estrogen, which tends to cause the gland to pool when blocked, and thus small granules may appear, which in severe cases may be yellowish in color or the granules may become larger, especially during pregnancy. Second, it may be due to the presence of sebaceous glands around the areola that secrete oil, a lubricant-like object that protects the nipple and areola better. It may also be due to other diseases, such as breast enlargement or mastitis, and it is best to see a doctor at a breast specialist for treatment on a case-by-case basis.
