What is a breast cyst?

Breast cysts are a common benign breast disease that does not pose a serious threat to health in most cases. They refer to fluid-filled cystic structures formed in the mammary ducts, usually appearing as soft lumps in the breast that are smooth to the touch and have clear boundaries, but do not grow fixedly.

The formation of breast cysts may be related to fluctuations in hormone levels, especially when estrogen levels are too high or hormone receptor sensitivity is enhanced. The breast ducts may expand and accumulate secretions under hormone stimulation, eventually forming cystic changes. This situation is more common in women of childbearing age, especially before and after the menstrual cycle, when the cysts may increase in size and be accompanied by breast pain. Sometimes, irregular diet, work and rest, or emotional stress may also be triggers.

Depending on the size and number, breast cysts may appear single or multiple, ranging in diameter from a few millimeters to several centimeters. Most cysts are asymptomatic and are only discovered during physical examinations or imaging studies. When the cyst is large, it may cause local pressure or obvious tenderness, but these symptoms often fluctuate with changes in the menstrual cycle. Breast cysts have no direct connection with breast cancer, but if the cyst is accompanied by non-absorbable solid components, further examination is required.

To relieve the discomfort caused by breast cysts, you can try to adjust your diet, reduce high-fat and high-sugar foods, and increase soy products to help regulate hormone metabolism; you can also relieve breast pain through hot compresses or warm showers. Pay attention to maintaining a regular schedule, avoiding excessive caffeine intake, and improving your lifestyle habits are positive for breast health. If the cyst is significantly enlarged, painful, or has other abnormal changes, it is recommended to seek professional breast imaging evaluation in a timely manner to clarify the nature of the lesion and carry out targeted treatment.
