Lumpectomy (sometimes known as a tylectomy) is a surgical removal of a discrete portion or lump of breast, usually in the treatment of malignant tumor or breast cancer.
Colectomy (col- + -ectomy) is bowel resection of the large bowel (colon). It consists of the surgical removal of any extent of the colon, usually segmental resection (partial colectomy). In extreme cases where the entire large intestine is removed, it is called total colectomy, and proctocolectomy (procto- + colectomy) denotes that the rectum is included.
