Myth 1: Breast enlargement does not need treatment, every woman has premenstrual breast swelling and pain. Breast Expert Opinion: Breast enlargement is typically characterized by premenstrual breast swelling and pain, which diminishes or disappears after menstruation. This is not normal. This disease is very common, many people take it for granted not to go to the clinic, some professional doctors also think that no treatment is needed, so that many breast enlargement aggravation, or even cancer. Myth 2: Breast enlargement can’t be cured, and it will naturally get better after giving birth to a child or going through menopause.

Myth 3: Breast enlargement does not need to be treated, it can be cured by itself. Breast expert’s point of view: there is a process of malignant transformation of normal breast epithelium, i.e. hyperplasia – atypical hyperplasia (precancerous lesion) – carcinoma in situ – invasive carcinoma. Clinically, cystic hyperplasia is atypical hyperplasia, and its histologic changes are irreversible and called precancerous lesions. The high incidence of breast hyperplasia and carcinoma is in two age groups: 30~40 years old for the first peak; 60~70 years old for the second peak. After menopause, the ovaries have no ovulation function, estrogen is mainly secreted by adrenal glands, and androstenedione hormone is converted into and produced in fats, liver, kidneys, and muscles.
