A surgical biopsy is a medical procedure where a surgeon removes a small sample of tissue from the body for examination. This sample is then analyzed under a microscope to help diagnose diseases, such as cancer or infections. Surgical biopsies can be performed on various parts of the body, including the skin, lungs, and organs. There are two main types of surgical biopsies: incisional biopsy, where only a portion of the tissue is removed, and excisional biopsy, where the entire lump or area of concern is taken out. The results from a surgical biopsy provide crucial information for determining the best treatment options.
