Mohs surgery is a highly specialized skin cancer treatment. This procedure is one of the most effective treatments for skin cancer because of its precision and accuracy.

You should know a few things about preparation for Mohs surgery before undergoing this treatment.

How do I prepare for Mohs surgery?

Your doctor will discuss the details of the procedure with you and answer your questions. After the surgery, you will be given instructions on how to take care of your wound.

You may also be advised to avoid certain activities before and after surgery, such as sun exposure and strenuous exercise.

Following all preoperative instructions provided by your doctor is crucial to a successful outcome. This includes avoiding taking medications that could interfere with healing or cause excessive bleeding during or after the procedure, such as aspirin or NSAIDs (non-steroidal anti-inflammatory drugs).

Smokers may also be asked to quit smoking before having the operation since it can hinder healing and increase complications.

What can I expect on the day of my surgery?

You must arrive on time and well-rested on the day of Mohs surgery so that you can focus on following your doctor's instructions.

The anesthesia used during the procedure may cause some drowsiness afterward, so you should have someone available to drive you home if needed.

Dress comfortably so you can access the area needing treatment; shorts or sweatpants are recommended over skirts or dresses for women.

The Procedure Itself

The surgeon will first inject an anesthetic into the affected area, then use a scalpel to remove the visible tumor and some surrounding healthy tissue. This tissue is then sent off to a lab, where it will be examined under a microscope.

Following this, the surgeon will contact the lab throughout the day to check if additional tissues need to be removed. Depending on how extensive the surgery is, this removal and examination process may take between one and four hours.

Is there anything I need to do after Mohs surgery?

You will be provided instructions for at-home care after your Mohs surgery. This involves keeping the wound covered with gauze and applying topical antiseptics regularly.

Depending on how much tissue was removed during surgery, some stitches may also be necessary to help close up any large wounds. These instructions need to be carefully followed to ensure proper healing after treatment.

You should also schedule regular follow-up appointments with your doctor to ensure there are no further treatments or precautions are needed.
