Understanding Excision in Surgery: Removing Tumors and Damaged Tissue

In the context of surgery, "excision" refers to the removal of a portion of tissue or an organ. The term is often used to describe the surgical removal of a tumor or other abnormal growth, as well as the surrounding tissue that may be affected by the growth.

For example, a surgeon might perform an excision procedure to remove a cancerous tumor from a patient's body. During the procedure, the surgeon would carefully remove the tumor and some surrounding tissue to ensure that all of the cancerous cells are removed. The excised tissue is then sent to a pathologist for examination to confirm that all of the cancerous cells have been removed.

In some cases, the term "excision" may also be used more broadly to refer to the removal of any unwanted or damaged tissue from the body. For example, a surgeon might perform an excision procedure to remove a damaged or non-functional organ or tissue that is causing problems for the patient.
