An excisional biopsy is a surgical procedure used to remove a tissue sample for examination. During this procedure, a doctor removes an entire lump or suspicious area, which allows for a thorough analysis. This method is often used to diagnose conditions such as cancer or infections. The removed tissue is then sent to a laboratory, where a pathologist examines it under a microscope. This examination helps determine whether the tissue is benign or malignant. An excisional biopsy can also provide information about the type of disease present, guiding further treatment options.
