Many women suffer from breast pain, which is the most common complaint among outpatients with breast problems. If self-examination reveals what appears to be a lump, people tend to panic and think they may have some bad disease. In fact, the majority of patients who come to the clinic because of breast pain are not diagnosed with tumors. Most breast cancers do not have pain as the first or main symptom, unless the tumor grows too fast in a short period of time, or the lump invades the nerves, etc., then some significant pain may appear. There is a particularly famous movie song in the United States, and one of the lyrics describes the silence as “as silent as a cancer cell growing”. In short, breast pain is caused by a very low percentage of malignant tumors in the breast, so I hope that when you read this, you will smile and put aside your worries about breast pain. There are many forms of breast pain, some are swelling, some are stabbing pain, and there are also radiating pains that are like electric shock, some don’t hurt when they don’t touch, some hurt the most when they undress, some hurt on both sides, and some only hurt on one side or even a small area. The most common explanation for these pains is the so-called “breast enlargement”. In addition, from the perspective of the cycle, the pain associated with menstruation is very regular, most of them are obvious bloating and pain during the premenstrual period, and the pain gradually decreases after the menstrual period, but there are also people whose pain increases after the start of the menstrual period. In addition, most of the pains that have no obvious pattern or cycle are also related to breast enlargement, and a few of them may have other causes such as trauma, inflammation, herpes zoster, etc. Some patients even confuse bone pain and anterior heart discomfort caused by coronary heart disease with breast pain. Pain caused by inflammation is often accompanied by red, swollen and burning skin, generalized fever, and localized pus breakouts, while typical herpes zoster has a band of distributed, but not midline, blisters. In general, there is no need to be nervous about breast pain, just go to the hospital in time. Of course, a few patients do go to the hospital because of breast pain and inadvertently discover other diseases of the breast, but even then the pain is not directly related to the disease discovered, which is just a coincidence because breast pain is so common. Therefore, the treatment of breast pain should be differentiated according to the cause and requires a diagnosis from your doctor, and blind panic is not necessary.
