Northwest Dermatology Group is your resource for Mohs surgery in Michigan. Mohs micrographic surgery (originally named for Dr. Frederick Mohs) is a specialized technique to remove skin cancer. It is typically performed on cosmetically sensitive areas. This procedure provides the highest possible cure rate while ensuring the maximum preservation of healthy, cancer free skin. Mohs surgery is often indicated for non-melanoma skin cancer (e.g. basal cell and squamous cell skin cancer of the head and neck region).

Also, The main surgical advantage of Mohs micrographic surgery is the microscopically controlled excision of the cancerous tissue. The Mohs surgeon precisely “maps out” the skin cancer and microscopically verifies that all cancer roots have been excised. The skin cancer is removed layer by layer, with only the minimal amount of tissue being removed. Confirmation of clear margins is obtained while the patient is in the office.

Mohs micrographic surgery is typically performed by a dermatologist with advanced fellowship training in this specialized technique. Most Mohs surgeons are certified by the American College of Mohs Surgery (ACMS- www.mohscollege.org).

What to Expect During Mohs Surgery

Mohs is performed on an outpatient basis using local anesthetic. In most cases, the procedure lasts several hours but could take all day depending on the depth of the skin cancer. During the procedure, the surgeon removes the visible skin cancer. The area is bandaged and the patient rests while the tissue is examined under a microscope. This process is repeated until all margins are cancer-free. Once the skin cancer has been completely removed, the wound is closed. In some cases, skin flaps or grafts are needed to close the wound. Most patients are able to resume light activities the day after the surgery. Patients should avoid strenuous activities for at least a week after surgery.

Preparation for Mohs Surgery

Preparation for Mohs Surgery Be sure to inform your surgeon of any medications or supplements you are taking. In most cases, Mohs is performed using local anesthetic so typically there are no diet restrictions leading up to surgery. Wear comfortable clothing on the day of your surgery. You may also want to bring a book to help pass the time.

Frequently Asked Question for Mohs Micrographic Surgery

We understand that a skin cancer diagnosis can feel overwhelming, and that the idea of surgery brings questions. Here are answers to some of the most common things our patients ask before their Mohs procedure.

Will Mohs surgery leave a scar?

Yes. Like any surgical procedure, Mohs surgery will leave some degree of scarring. However, because the technique removes tissue in thin, precise layers, it preserves significantly more healthy skin than traditional excision, which typically results in a smaller and less noticeable scar. According to Mount Sinai, post-surgical scars continue to improve over time and can take up to a year or more to fully mature. During the healing process, some redness and skin tightening around the site is normal, typically peaking around four to six weeks after surgery. Our surgeons prioritize both complete cancer removal and the best possible cosmetic outcome when planning reconstruction.

How long is the recovery after Mohs surgery?

Most patients return to light daily activities the day after surgery, and many are back at work within a few days. The Cleveland Clinic recommends avoiding strenuous physical activity for at least a week to prevent bleeding or stress on the wound. Sutures are typically removed within five to ten days. The wound itself generally closes within four to six weeks, though complete scar maturation continues for several months. Protecting the surgical site from sun exposure during the healing period is important, as UV exposure can worsen scarring and slow recovery.

What makes Mohs surgery different from standard skin cancer removal?

The key difference is real-time microscopic verification. During traditional excision, a surgeon removes the visible cancer along with a margin of surrounding tissue and sends it to a lab, with results returning days later. With Mohs, each layer of tissue is mapped, removed, and examined under a microscope while you wait, so the surgeon knows with certainty whether cancer remains before removing any additional skin. According to the Mount Sinai Mohs Surgery program, this precision is why Mohs achieves cure rates as high as 99% for new skin cancers, while preserving the maximum amount of healthy tissue. It is particularly valuable for cancers on the face, ears, nose, and other areas where preserving tissue matters most.
