More in Surgery. Excision means to surgically remove. This term is often used in reference to removing a mass, excision means that tissue is removed, using a scalpel, laser or another instrument. Excision refers to completely removing the tissue in question, rather than just a part, as is done in a biopsy. While the term excise is often used to describe a large range of procedures that remove tissue during surgery, the precise use of the term means removing an entire structure using some type of cutting instrument.
Excisions are usually larger and deeper and are used to completely remove an abnormal area of skin such as a skin cancer. These are not technically biopsies since the goal of this procedure is to remove the whole lesion rather than to remove a small portion to make a diagnosis.
