What causes breast cysts?

Breast cysts are usually caused by blocked breast ducts or glandular secretion disorders and are usually benign, but the specific situation needs to be judged based on the examination results.

Breast cysts are small fluid-filled sacs in the breast. Their formation is often related to hormonal fluctuations. For example, increased estrogen levels may stimulate breast tissue proliferation, leading to the appearance of cysts. Their occurrence is usually related to hormonal changes in the menstrual cycle, family history, lifestyle, stress and other factors. Some cysts may manifest as breast tenderness or palpable lumps, but in most cases they do not cause obvious discomfort.

Cysts of varying sizes can sometimes be mistaken for other breast problems, but they are fluid in nature, not lumps. If the cyst is small or asymptomatic, no special treatment may be needed; however, if the cyst is large and presses on surrounding tissues causing discomfort, further testing and even drainage may be required. In addition to benign breast cysts, other lesions such as breast tumors may present with similar symptoms, so regular examinations are important.

To reduce the risk of breast cysts or relieve symptoms, it is recommended to develop a healthy lifestyle, such as controlling weight, reducing high-fat diet, quitting smoking and limiting alcohol, and exercising moderately. If you feel persistent breast pain or touch an abnormal lump, you should go to the hospital for examination as soon as possible to identify the cause and get professional guidance.
