Excision will explain to you why the skin lesion needs excision and the procedure involved. You may have to sign a consent form to indicate that you understand and agree to the surgical procedure.
Tell your doctor if you are taking any medication (particularly aspirin, clopidogrel, dabigatran and warfarin, which could make you bleed more), or if you have any allergies, medical conditions, or a pacemaker or implanted defibrillator. Remember, to tell your doctor about any over-the-counter supplements or herbal remedies as a number of these can also lead to abnormal bleeding.
The area to be excised is marked with a surgical marker. A local anaesthetic injection will rapidly numb the area of skin involved and keep it numb during the procedure. The dermatologist will then cut around and under the lesion with a scalpel and sharp scissors along with an appropriate margin of normal surrounding tissue. The lesion is placed in formalin ready to go to the pathology laboratory. Here, a pathologist will process and examine the specimen under the microscope, and provide your doctor with a report a few days late.
