What is the test?
Doctors take biopsies of areas that look abnormal and use them to detect cancer, precancerous cells, infections, and other conditions. For some biopsies, the doctor inserts a needle into the skin and draws out a sample; in other cases, tissue is removed during a surgical procedure.
For this test, abnormal areas of skin are removed to test for cancer or other skin diseases.
How do I prepare for the test?
Tell your doctor if you have ever had an allergic reaction to the medicine lidocaine or similar types of local anesthesia.
