There are several types of mastectomy procedures, including: 

• Total Mastectomy (Simple Mastectomy): This is the removal of the entire breast, including the nipple and areola, as well as the underlying muscles if necessary. 
• Modified Radical Mastectomy: This procedure involves removal of the entire breast, including the nipple and areola, some of the lymph nodes under the arm, and the chest wall muscles if necessary. 
• Radical Mastectomy: This is the removal of the entire breast, chest muscles under the breast, and the lymph nodes under the arm. This procedure is rarely performed today and is typically replaced by the modified radical mastectomy. 
• Lumpectomy (Breast-Conserving Surgery): This procedure involves removal of only the tumor and some surrounding tissue, while preserving most of the breast. 
• Nipple-Sparing Mastectomy: This procedure involves removal of the breast tissue but preserving the nipple and areola. 

It’s important to note that the type of mastectomy a person undergoes will depend on various factors, including the size and location of the tumor, the stage of the cancer, and the patient’s overall health. Your doctor can help determine the best option for you based on your individual needs.
