Mohs Skin Cancer Surgery


When you are facing skin cancer, you deserve treatments that are fast and effective while causing minimal scarring. Any type of cancer causes immense stress, and melanoma is the deadliest form of any skin cancer. Fortunately, all types of skin cancer can be easily and quickly treated without invasive surgeries when caught early. That is why it is so important to keep your annual skin checks with a qualified dermatologist. Only these trained professionals can catch the signs of skin cancer early. The earlier the skin cancer is diagnosed, the easier it is to treat.

Traditionally, testing for skin cancer or removing early-stage skin cancer required multiple appointments. One appointment would require the biopsy, or removal of the suspect site. Oftentimes, dermatologist would remove an ample area of the skin to help decrease additional biopsies in the future. However, this resulted in larger scars that could have been unnecessary.

Patients had to wait days or sometimes weeks for their biopsy results to return from an off-site lab. The wait was often more stressful than the procedure. Mohs micrographic surgery has changed all of this, and Spectrum Dermatology is one of the few clinics in the Phoenix and Scottsdale area that offers this innovative procedure.

Mohs Micrographic Surgery

Mohs micrographic surgery is simple but very effective. It relies on the idea that having a biopsy lab on-site will dramatically reduce a patient’s stress, time, and money spent when facing skin cancer. The technique combines traditional methods of diagnosing and treating skin cancer in a single appointment. Mohs uses a precise microscope to identify areas of the skin that are cancerous.

A Mohs micrographic surgery begins like any other skin biopsy, but with one big difference. The area removed is much smaller than traditional biopsies. The goal is to minimize tissue removal and scarring. Next, the biopsy is taken to the lab located within Spectrum Dermatology for analysis in real-time.

If the biopsy has borders that are “all clear” from skin cancer, the surgery is complete. If there are parts of the border still showing cancerous cells under the state-of-the-art technology, an additional, very small removal takes place. This process is repeated until the patient receives an all clear. Results are immediate, and the patient ultimately undergoes a single surgery. They are not prepped for recovery until the borders read as clear.

“If having skin cancer surgery could ever be described as “fun”, my last visit with Dr. Thosani and Victoria was “fun!” Their personable approach and professionalism crossed in a timely manner and kept me very much at ease with the surgical procedure. I have confidence in Dr. Thosani and trust her capability to know what treatment is best for me … If laughter truly is the best medicine, (we) all possibly overdosed on this visit.”

Mohs and Skin Cancer

Many types of skin cancer can be diagnosed and treated with Mohs micrographic surgery. These cancers include those in areas that are particularly difficult, such as near the eyes, lips, nose, on fingers and toes, the genitals, and scalp. Aggressive cancers and larger areas can also be treated with this type of surgery. Even recurring cancers are effectively treated with Mohs micrographic surgery.

A Mohs Surgery Breakdown

  • Dermatologists know that an irregular mole is just one sign of skin cancer. When cancer is prevalent in a mole, the cancerous borders may extend beyond the borders of the mole. Failure to remove the full cancerous area means the cancer has not been removed and may continue to grow.
  • First, only the visible (mole) part of the skin is removed.
  • This skin is divided into sections in the Mohs lab. The surgeon codes each section to reference them in the future. A surgical site map is created to mark exactly where the cancer occurred.
  • The bottom and edges of each section are expertly examined on-site.
  • If the cancer extends to the bottom of the sample or to the borders, another small area of skin is removed—however, skin is only removed from areas where cancer cells are still prevalent.
  • Mohs surgery stops when no cancer evidence remains. This keeps as much of the healthy tissue intact and drastically reduces scarring.
