Mammary gland hyperplasia is the most common breast disease in women, and its incidence accounts for the first place in breast diseases. About 70-80% of women have mastopexy to varying degrees, mostly between the ages of 25-45. This is related to endocrine disorders. The most obvious symptom of mastocytosis is breast swelling and pain: unilateral or bilateral breast swelling and pain or tenderness is common. Most patients have cyclical pain that occurs or worsens during the premenstrual period and decreases or disappears after menstruation. Some people also have breast lumps: the size and texture often change cyclically with menstruation, with the lumps increasing in size and texture during the premenstrual period, being hard, movable and not adhering to the surrounding tissue, and shrinking and softening after menstruation. There is no definite and effective treatment for mastocytosis, and some patients can often go into remission on their own after a few months to 1-2 years after the onset of the disease, so they do not need treatment. If the symptoms are obvious, you can take some oral Chinese or Western medicine for hyperplasia, and pay attention to rest, emotional regulation, and regular work and rest to slowly relieve it. For patients with extensive lesions, a bra can be used to support the breasts and some herbal medicines to activate blood circulation and remove blood stasis may be effective. Mild mastocytosis is not associated with cancer. In fact, there is no need to be so alarmed. Mild breast enlargement is caused by the high level of estrogen in a woman’s body environment for a long time, which stimulates the breast ducts and is neither inflammation nor tumor. Women who are older and unmarried, who have not had children or breastfeeding, and who are depressed are most likely to get this disease. The high incidence of breast cancer is between 45 and 55 years old. Although there is a trend of youthfulness, it is still rare for women in their twenties to get breast cancer clinically, so young women do not need to be too nervous. However, women with family history of breast cancer and endocrine disorders should be very careful. “However, if breast enlargement is serious or accompanied by cysts, it is not a simple problem. It is better to go to the hospital once every six months for examination to better prevent malignant changes in benign breast diseases or to detect malignant diseases as early as possible. Even so, women do not have to worry too much. Mammary hyperplasia and breast cancer are, after all, two different diseases, and mammary hyperplasia is not an early stage of breast cancer.” For women with breast enlargement, they should pay attention to the following points: 1. Breast enlargement should be monitored frequently and a physical examination should be done once a year. 2. You should learn to self-examine and check your breasts during the days between your menstrual periods, when you take a shower, and feel for lumps. 3.When the lump increases, pain loses its regularity, nipple overflow and orange peel-like changes in the breast skin, you should seek medical attention promptly. This is usually a sign of breast cancer. In addition, emotional instability can inhibit ovulation function of ovaries, and there is a decrease in progesterone, which makes estrogen relatively higher and leads to breast enlargement. In terms of diet, it is important to reduce the intake of meat foods and eat more fresh vegetables and fruits.
