Resection

 A resection is a type of surgical procedure that is performed to remove an area of abnormal tissue from the body.  A resection usually removes all of the abnormal tissue plus some normal tissue. The normal tissue is called the margin.

 

A resection may remove an entire organ or parts of several organs connected to the abnormal tissue. A resection is usually performed when the abnormal tissue cannot be removed safely with a smaller type of procedure such as an excision or a biopsy.

Resections are commonly performed to remove tumours and the procedure may be given a special name depending on the location of the tumour.
