STEP 1
After anesthetic, a thin layer of the patient's skin is removed.
STEP 2
The tissue is mapped and sliced into thin layers.
STEP 3
After complete removal of the cancer is confirmed, the doctor will reconstruct the wound with several layers of sutures.
STEP 4
The doctor uses a microscope to look for cancer in the deepest layers of the patient's skin. If any cancer remains, additional layers will be removed.
Shave biopsy
A shave biopsy is a procedure used to remove and microscopically examine potentially abnormal tissue, called skin lesions, located in the most superficial layers of the skin. After anesthetic, a scalpel is used to remove the top layer of skin in an affected area.
Excisional biopsy
An excisional biopsy is used to remove larger, deeper skin lesions. Depending on the site, a few stitches may be needed to close the wound.
Punch biopsy
A punch biopsy is a procedure that involves using a cylindrical punch tool to remove tissue from all layers of the skin. All biopsies are sent to a pathologist for microscopic examination.
These are additional tools the surgeon may use to remove the tumor. Curettage involves using a round, dull instrument (curette) to scrape away cancerous tissue.
Electrodessication involves using an electrocautery unit to remove remaining cancerous tissue and promote coagulation. The curette is used again over the surgical site to remove any excess tissue.
