Generally speaking, the female breast gland undergoes monthly cyclical changes due to the action of estrogen and other hormones. When hormone levels rise, the gland becomes hyperplastic, and when hormone levels fall, the gland recovers. Due to the inconsistent density of hormone receptors in each gland or the sensitivity of the gland to hormones, there are inconsistencies in the degree of recovery of each gland, resulting in thickening of the gland, formation of hard lumps, and even tumor-like hyperplasia. Benign breast diseases can be broadly classified into three types: 1) non-proliferative lesions; 2) proliferative lesions; and 3) proliferative with atypical hyperplastic lesions. Generally speaking, only the third type has the possibility of malignant change. According to your examination results, it should be the first case. Treatment can be done with some traditional Chinese medicine, but also hot compresses, massage, etc., can achieve relief of pain symptoms. In addition, attention needs to be paid to the appropriateness of the bra. 50% of people have breast pain related to bras.
