If the cyst in the axilla is relatively small, with a diameter of about three centimeters, it can be operated under local anesthesia, and the cost is about 500 dollars. After the axilla is sterilized with iodine, local anesthesia with lidocaine, an incision along the skin line is made to remove the cyst completely, and then the wound is sutured. If the cyst in the armpit is larger, it routinely requires hospitalization for surgery, which costs relatively more, possibly around 3,000 yuan. Because there are more tests for inpatient surgery, there will be blood tests, biochemistry, coagulation, as well as electrocardiogram and ultrasound. At the same time, preoperative anesthesia is required, mainly brachial plexus anesthesia. After the anesthesia is ready, the skin is cut in the armpit and the cyst is removed completely. Care should be taken to avoid damaging the axillary vein and nerves. After surgery, the cyst is routinely sent for pathologic examination, and the incision is sutured up.
