The correct answer identifies mastectomy as the procedure that involves the surgical removal of dominant cancer-influenced breast tissue. This operation is often performed when there is a significant risk of breast cancer or when cancer has already been diagnosed and requires removal to manage the disease effectively. In a mastectomy, either a portion (segmental mastectomy) or the entire breast (total mastectomy) may be removed, depending on the extent and characteristics of the malignancy.

This surgical option is particularly pertinent in cases where the cancer is invasive, and ensuring complete removal of the tumor is crucial for treatment efficacy. Mastectomies are often recommended when the tumor is large relative to the breast size or when multiple areas of the breast are affected.

Other terms such as lumpectomy, resection, and excision carry different implications in surgical practice. Lumpectomy is specifically the removal of a small, localized portion of breast tissue, typically for smaller tumors. Resection generally refers to the removal of a part of an organ or structure, which can apply to various types of surgery beyond breast cancer. Excision broadly indicates cutting out tissue but does not specify the context in relation to cancer or the extent of the removal. Hence, mastect
