What causes breast cysts

Patient's question:

What is a breast cyst? How is it treated?

Doctor's answer:

Hello, common breast cysts include simple cysts, lactational cysts, etc. Simple cysts are the most common type of breast cyst. They are primarily caused by endocrine disorders leading to the proliferation of ductal epithelium, an increase in intraductal cells, resulting in duct extension, tortuosity, and folding. In the folded areas, the duct wall undergoes necrosis due to ischemia, forming a cyst. Lactational cysts are formed during lactation when milk drainage is obstructed in one lobule, causing milk to accumulate within the breast. Breast cysts have a certain risk of malignancy, so specialists recommend conservative drug treatment for cysts under 0.6 cm, adopting a combination of traditional Chinese and Western medicine, which is highly effective. For cysts larger than 0.6 cm, surgical treatment is recommended. Specialists advocate for the Mammotome minimally invasive surgery for breast cysts, which can be performed under ultrasound guidance for minimally invasive treatment. This minimally invasive surgery can remove multiple adjacent masses through a single incision (a small 3mm needle hole). Furthermore, it does not require hospitalization post-surgery, carries minimal risks, and has fewer complications. Most importantly, for someone of your age (22), the post-surgery result is just a single 3mm needle hole with no scars. There is also the traditional open surgery, which is more economical but leaves scars and involves significant bleeding, requiring hospitalization for observation and having more complications. You can choose based on your own circumstances.
