The duration of breast pain before menstruation varies depending on an individual's constitution. Typically, breast pain is a sign that menstruation is approaching, and the symptoms will gradually disappear after the onset of menstruation. If the symptoms are mild, there is no need for treatment. It is important to rest adequately and avoid overexertion. Applying a warm towel to the breasts can help alleviate the pain. Additionally, it is important to maintain a good mood and attitude during menstruation and when experiencing breast pain, and avoid becoming angry or anxious.

Can breast distension and pain be treated with moxibustion?

Breast distension pain can be treated with moxibustion, but the results might not always be satisfactory as breast distension pain is related to mammary gland hyperplasia, which is believed to be connected to increased estrogen levels caused by endocrine disorders. Generally, we use traditional Chinese medicine for treatment, which relieves pain through methods that soothe the liver and regulate Qi, and harmonize the thoroughfare and conception vessels. Endocrine treatment is also an option but is used as sparingly as possible. However, it can be administered before menstrual onset in cases where pain is significantly pronounced in the pre-menopausal phase. Regular pelvic ultrasound re-examinations must be conducted during endocrine treatment due to the increased risk of endometrial cancer that this treatment might entail. Treatment with vitamins such as vitamin B, vitamin C, and vitamin E can also be used, as they aid in improving liver function, regulating sex hormone metabolism, and enhancing autonomic nervous system functions, serving as adjunctive medication for this condition. (Medication should be taken under the guidance of a physician.)

Is bilateral breast pain breast cancer?

Bilateral breast pain generally is not considered breast cancer, but rather breast hyperplasia. Diagnosis can be confirmed through breast ultrasound and mammography. The ultrasound of breast hyperplasia typically shows uneven low echo areas; if cysts are present, they appear as anechoic areas. Mammography may display a ground-glass or cotton wool-like shadow. However, it is important to be cautious of the possibility that breast hyperplasia and breast cancer may coexist. On one hand, patients with significant hyperplasia should be closely followed up, advised to return to the hospital every two to three months for follow-up examinations. On the other hand, patients with significant proliferative lumps or unclear boundaries in thickened breast areas are recommended to undergo a biopsy of the suspicious lesions to prevent misdiagnosis.

What is the cause of breast pain before menstruation?

Many women experience breast pain before each menstrual period, but what exactly is the cause? Mild breast pain may be due to changes in hormones within the body and is considered a normal physiological condition. Of course, it could also be caused by diseases, such as the commonly seen fibrocystic breast changes, which result in cyclical breast pain associated with the menstrual cycle. There are also other diseases that can cause cyclical breast pain, which should be taken seriously. Especially in cases of severe pain, where even slight touch causes significant discomfort, it is advised to seek timely medical examination at a hospital.

Will the breasts still swell and hurt if there is a miscarriage in early pregnancy?

In early pregnancy, if the fetus stops developing, some of the early pregnancy symptoms in the pregnant woman will gradually ease, but the easing process will not happen immediately. For example, breast tenderness can persist for a period of time, usually easing after a week as levels of human chorionic gonadotropin, estrogen, and progesterone decrease, resulting in relief from breast pain. In early pregnancy, if embryo arrest occurs, it is advisable to take treatment measures promptly to address the non-developing gestational sac. Options include surgical abortion or medical abortion.

What is the cause of breast swelling and pain?

Breast pain is generally related to breast hyperplasia, and it can be diagnosed through the use of breast ultrasound or mammography. Currently, breast hyperplasia is believed to be associated with disruptions in the endocrine system leading to elevated levels of estrogen. Factors such as the external environment, work and living conditions, interpersonal relations, and various other stresses that cause neuropsychiatric impacts can alter the internal environment of the body. This, in turn, affects the function of the endocrine system, leading to abnormal secretion of one or more hormones. During the menstrual cycle, the receptors in the breast tissue undergo cyclical changes due to the fluctuation of hormone levels. An imbalance where estrogen levels are high and progesterone secretion is reduced can result in incomplete regression of breast hyperplasia after the growth phase, causing breast tissue hyperplasia. Additionally, differences in the quality and quantity of estrogen receptors in the breast tissue may contribute to uneven growth levels across different parts of the breast.
