An excision biopsy is a surgical procedure that involves removing a small piece of tissue or an entire lesion from the body for further examination. It is often used to diagnose and treat suspicious or cancerous growths, such as moles, lumps, or tumors.
During the procedure, the area around the growth is first numbed with a local anesthetic. The surgeon then removes the entire growth, along with a small amount of surrounding tissue, using a scalpel or other cutting tool. The tissue sample is sent to a laboratory for analysis to determine whether the growth is cancerous or benign.
"Excision biopsy is a safe and effective method for removing abnormal or suspicious tissue. It allows for precise removal of the affected area and can help prevent the spread of cancer or other diseases." - National Cancer Institute
