The size of breast cyst surgical excision incision is mainly related to the surgical method, and the size of the incision varies from about 1~3cm. Breast cyst excision mainly includes traditional surgical excision and ultrasound-guided minimally invasive excision. 1. Traditional surgical excision: 2~3cm incision is made on the surface of the cyst, and the cyst is directly found and then excised. 2. Minimally invasive resection: minimally invasive instruments under ultrasound guidance enter underneath the swelling to perform rotational resection, usually the incision is usually less than 1cm. Both traditional surgery and minimally invasive surgery can effectively remove breast cysts. For aesthetic reasons, minimally invasive surgery is better than traditional surgery, but the price is relatively high. It is recommended to follow the doctor’s advice to choose the appropriate treatment according to your own situation. It is recommended that patients with breast cysts who want to undergo surgical treatment should consult a regular hospital and choose the appropriate treatment method under the guidance of a doctor.
