Chemical cautery is a medical procedure that uses chemical agents to destroy tissue. This technique is often employed to treat conditions like warts, skin tags, or certain types of lesions. Common chemicals used include silver nitrate and trichloroacetic acid, which work by causing a controlled burn to the targeted area. The procedure is typically quick and can be performed in a doctor's office. After application, the chemical agent reacts with the tissue, leading to its destruction and eventual healing. Patients may experience some discomfort, but the recovery time is usually short, making chemical cautery a convenient option for minor skin issues.
