A shave biopsy is a medical procedure used to remove a small section of skin for examination. During this procedure, a doctor uses a small blade to shave off the top layers of skin, which may include abnormal tissue. This technique is often used to diagnose skin conditions, including skin cancer. The sample obtained from a shave biopsy is then sent to a laboratory for analysis. The results help the doctor determine the nature of the skin lesion and decide on further treatment if necessary. Shave biopsies are typically quick, minimally invasive, and can be performed in a doctor's office.
