An excisional biopsy is a surgical procedure used to remove a tissue sample for examination. This method is often employed when a doctor suspects the presence of abnormal cells, such as in cases of cancer or tumors. The entire lesion or mass is typically removed, allowing for a thorough analysis. During the procedure, the patient is usually given local anesthesia to minimize discomfort. The removed tissue is then sent to a laboratory, where a pathologist examines it under a microscope. This helps in diagnosing conditions and determining the appropriate treatment plan for the patient.
