Excision is a medical term used to describe the process of cutting out a part of the body. It is a surgical procedure that involves removing a part of the body, such as a tumor or an organ, with a scalpel or other sharp instrument. The EXCISION procedure is often used to treat cancer or other diseases, and can also be used for cosmetic purposes. In some cases, the EXCISION may be done in combination with other treatments, such as chemotherapy or radiation therapy.
