Surgical treatment is still one of the main treatments for breast cancer. There are many surgical methods, but there is still no consensus on their choice. The general development trend is to minimize surgical injuries. When the equipment conditions permit, patients with early breast cancer should try their best to keep the breast shape. No matter which surgical method is chosen, radical treatment is the main method, supplemented by function and morphology.
