In response to the question that breast cysts must be operated on, the first direct answer given is that they don’t have to be. Cyst is the medical terminology, that is, there is a large blister inside the breast, this blister may be very small, small can be as small as the size of sesame seeds, large can be as large as very large, up to more than ten centimeters, like a duck egg as large as a cyst, goose egg as large as a cyst can be encountered. Breast cysts need to be considered for surgery in the following three cases: 1. Breast cysts are too large, which can cause pain or make the patient uneasy, and suddenly become bigger, that is, there may be cystic bleeding inside, in which case surgery can be considered; 2. Regardless of how big the cyst is, even if it is so small that it is only as big as a soybean or a green pea, but under ultrasound, molybdenum target or magnetic resonance, it is found that there is localized thickening of the wall of the cyst, and there is a protrusion in the capsule, in which case cancer should be highly suspected. In this case, the risk of cancer should be highly suspected, and surgery must be performed, regardless of the size; 3. Breast cysts should be considered for surgery is that there are people who are particularly stressed mentally, have breast cysts, Baidu or other search engines, breast cysts are precancerous lesions, in this case, she can’t sleep at night, and she doesn’t think about her food, and she must undergo surgery, and I’ve seen that if she doesn’t do the surgery for me, I don’t want to live. In this case, the doctor can take out the cyst through biopsy, which is a very small operation, such as making a small incision of 4-5mm with a minimally invasive method, and then do the laboratory tests, telling him that he can rest assured that this is absolutely fine. Other than these three surgical conditions, all breast cysts do not require surgical intervention. So whether breast cysts need surgery or not, except for the three conditions just mentioned, none of them need to be actively dealt with.
