The choice of treatment options for ductal dilatation depends on the different characteristics of the disease, and the specific treatment methods are as follows: 1. lobectomy, for lesions that are limited in extent, with relatively mild inflammation of the mammary glands and nipple overflow that is only yellow and not bloody, the necrotic lobules can be removed and the normal breast tissue preserved. 2. subcutaneous mastectomy, for lesions that are more extensive, with hard lumps of varying sizes in the nipple and areola, and with pressure pain in the breast, pus flowing from the nipple and even fistulas. If you have a lump in the nipple or areola that is widespread and is accompanied by pressure pain in the breast, pus flowing from the nipple or even a fistula, this procedure should be performed to preserve the nipple and the unchanged breast tissue. 3. incision and drainage, if a lump is formed in the breast and there is an abscess that is painful, you need timely anti-infection treatment, taking antibiotics and timely incision and drainage, and after the infection has improved, surgery is performed.
