Breast hyperplasia can be treated with medication, but due to the disorder of hormone levels in the body, incomplete recovery may lead to the possibility of recurrence of breast hyperplasia. Most cases of breast hyperplasia are believed to be related to endocrine disorders, causing elevated estrogen levels, and hormonal levels in the body change periodically. When the proportion of hormones in the body is unbalanced, estrogen increases, and progesterone secretion decreases, breast hyperplasia is incompletely restored, causing breast tissue proliferation. On the other hand, it may also be related to the differences in the quality and quantity of estrogen receptors in the breast parenchyma components, resulting in uneven growth in different parts of the breast.
