Mammary gland hyperplasia is a common disease in women, mainly related to endocrine disorders in patients, with women aged 20-50 as the main group of patients. Self-detection of the disease by hand in clinical practice is not difficult, but the distinction with breast cancer should be noted. Self-detection of mastocytosis through symptoms is usually recommended in the premenstrual period, and auxiliary examinations can also be performed to further confirm the diagnosis. I. Clinical manifestations 1. Breast swelling and pain: characterized by pain related to the menstrual cycle, often increasing before menstruation (usually about 7 days before menstruation) and decreasing or disappearing after menstruation, but the above pattern can disappear in those with longer disease duration; 2. Use the palm surface of the fingers, not the fingertips, for palpation, and do not pinch the breast tissue with your fingers.

X-ray examination: the hyperplastic breast tissue is cotton wool or hairy glass-like density enhancement shadow, if there is cystic hyperplasia, it can be seen that there are round translucent shadows in the enhancement shadow; 2. infrared transillumination examination: there is generally no obvious abnormality in the transillumination of mammary gland hyperplasia, the translucency can be weakened at the obvious hyperplasia, and the vascular image is normal. Daily health care 1. keep a relaxed mood; 2. pay attention to a reasonable diet and eat more vitamin-rich food; 3.
