Breast pain is one of the common symptoms of breast. In clinical work, we can often see many patients with breast pain running to the hospital over and over again and taking Chinese and Western drugs for a long time, which is not only laborious but also may damage their health because of the side effects of drugs, which is very unfavorable to patients. The main reasons why breast pain patients run to the hospital frequently and keep using drugs are as follows: 1. Fear of breast cancer. Once there is pain in the breast, they always worry whether breast cancer has occurred or the pain will cause breast cancer after a long time, so they seek medical help frequently. 2. Thinking that breast pain must be some kind of breast disease. In clinical practice, most of the breast pain will be diagnosed by doctors as breast enlargement, and the pain is not good after the medication is administered according to medical advice, or it appears again soon after relief, so patients are worried that if breast enlargement is not cured, it will cause other problems after a long time, so they keep using medication. 3, some heavier breast pain does affect the patient’s life and work, and requires treatment. The cause of breast pain is generally related to the menstrual cycle, under the action of hormones, the pre-menstrual breast hyperplasia, rich glands, cell enlargement, inter-mammary tissue edema and caused by the onset of menstruation, estrogen levels decline, the above changes disappear, the breast also followed by relaxation and softness, swelling and pain significantly reduced or disappeared, and the symptoms recur before the next period. It is generally divided into physiological causes and pathological causes. Most of the causes of breast pain in women are normal physiological phenomena and do not require special tension. For example, breast development during adolescence, menstrual distension, breast distension due to estrogen changes during pregnancy, breast distention after childbirth, breast distention due to endocrine imbalance in women after abortion, and disharmony in sexual life can also lead to breast pain. Pathological causes include heavier hyperplasia of the breast, inflammatory lesions of the breast, malignant tumors of the breast, etc.
