Understanding what tissue is removed defines the different mastectomy options. Removing breast tissue along with axillary lymph nodes targets both the tumor and potential spread through the lymphatic system, which is why this approach is described as a modified radical mastectomy. In this procedure, the entire breast is removed and the axillary lymph nodes are removed, but the chest wall muscles (such as the pectoralis major) are preserved.

For contrast, a simple (total) mastectomy removes only the breast tissue without axillary node dissection or chest wall muscle removal. A radical mastectomy involves removing the breast, axillary lymph nodes, and chest wall muscles, which is more extensive. A lumpectomy, on the other hand, removes only the tumor and a small margin of surrounding tissue, preserving most of the breast and usually not removing axillary nodes.

So the description fits the modified radical mastectomy.
