Mohs Surgery

Mohs micrographic surgery is a precise surgical technique of progressively removing thin layers of cancer containing skin until only cancer free skin remains. It is used in cases of skin cancer generally on an out-patient basis.

Know More About Surgery

Mohs surgery may be required in the following conditions:

  • A mole that suddenly becomes tender and painful
  • A mole that begins oozing, bleeding etc.
  • Sudden pigmentation of a mole
  • A dark spot near or next to an existing mole

Prior to Mohs surgery, it is essential to carry out the following:

  • Biopsy
  • Microscopic examination

The steps involved in Mohs surgery are:

  • Surgical removal of the tissue
  • Mapping the tissue followed by freezing & cutting (by a Cryostat), staining the tissue either with eosin & hematoxylin or with toluidine blue
  • Interpretation of these stained tissues by using microscopic slides
  • Reconstructing the defect if possible

The risks involved in Mohs surgery are:

  • Pain
  • Redness
  • Drainage
  • Infections

After Mohs surgery, it is essential to keep in mind the following:

  • Specific instructions about wound & reconstructed area are given by the doctor which has to be followed
  • Usually the area repaired is covered with a bandage for at least one week
  • In case of non-absorbable stitches the period may range to two weeks or more until the stitches are removed

FAQ Section

1) What is Mohs micrographic surgery?

Named after its inventor, Dr. Frederic Mohs, Mohs micrographic surgery is a microscopic surgical procedure that is used to remove skin cancer. Thin layers of skin are surgically removed and processed by horizontal sectioning, and If cancer is detected within the tissue margins, the cancer is then mapped and another layer or stage is taken, and the process is repeated until there is no cancer
within the tissue margins.

2) Is Mohs a good treatment for skin cancer?

Numerous studies have shown that Mohs micrographic surgery is simply the best way to check a surgical margin to ensure the cancer is completely removed so there is less chance of any cancer to return. In these studies, Mohs surgery had the highest cure rate for skin cancer removal and proved to be most useful in removing recurrent skin cancers.
There are several aspects of the Mohs Surgery that make the procedure both unique and superior to
other methods of treating skin cancer.
1.Highest cure rate among skin cancer treatments.
2.Compared to other skin cancer treatments, chances of errors are less.
3.Increases accuracy of skin cancer removal.
4.It has immediate results.
5.Decreases the amount of healthy tissue removed.
6.Minimizes surgical risks and scarring.
7.Performed under local anesthetic.
8.Can be less expensive than other treatments.
9.Can result in quicker recovery.

3) Is Mohs surgery the most cost-effective treatment option?

Because of Mohs high success rate, most patients require only a single surgery, which usually includes the repair of the wound as well. Other methods might require extra surgeries and pathology readings in order to repair the wound and to treat cancer if it is not completely removed, and each of these additional surgeries and pathology readings would require separate fees. A single Mohs surgery procedure includes all of these into one fee, making it the most cost-effective treatment for skin cancer.

4) What are possible complications of Mohs?

Although a very safe and effective surgical treatment for skin cancer, like any surgery or procedure, Mohs surgery has some possible risks and complications, they are generally outweighed by the benefits. Common risks of Mohs surgery are not only limited to swelling and bruising. Scarring is also a possibility with any surgery and a wound can be sometimes slow to heal. Numbness and tingling can be present for weeks or for months, but they will usually resolve. Some rare risks include excessive infection, bleeding, paralysis, and pain. Mohs surgery can minimize both these surgical risks and scarring because the procedure keeps the wound as small as possible by removing very little healthy tissue.

5) Will Mohs surgery leave a scar?

Yes, like any treatment for skin cancer, Mohs will leave a scar. While removing the tumor, Mohs preserves as much healthy skin as possible and maximizes options for repairing the surgical defect. Generally, a post-surgical Mohs scar improves with time and can take up to one year or more to fully mature. As your surgical site heals, new blood vessels can appear and promote the healing changes
occurring underneath the skin. This can result in the reddish appearance of the scar, which is temporary and will improve with time.

6) What is reconstruction?

Mohs micrographic surgery will create a wound when the cancer is removed, and more cancer there is, the wider or deeper the wound will be. Reconstruction involves closing the wound after the cancer is surgically removed by Mohs, and the type of reconstruction will depend on if the wound is in an optimal location or difficult location, and if the wound is small or large.

7) How long does Mohs surgery take?

Although Mohs surgery can take longer than other procedures to perform, improvements in technology, such as automated staining of tissue samples, have made the procedure quicker. While it is difficult to predict exactly what timeframe to expect for each Mohs surgery procedure, the entire surgery usually lasts several hours. Seldom, clearing the tumor and repairing the defect can take the better part of a day.

8) What areas are treatable by Mohs surgery?

Mohs micrographic surgery is used to treat skin cancers primarily on the face where there is not a lot of extra skin to spare and where scars can be more pronounced. Researches have shown that Mohs surgery is the best option for treatment of skin cancer on the nose, lip, eyelid, and ear. The Mohs surgery is also highly recommended for cancers that are likely to return, have already recurred or have ill-defined borders that make the true area of cancer hard for the surgeon to see.

9) Why does your skin cancer need to have Mohs surgery?

Mohs micrographic surgery has the highest cure rate. It is appropriate for most skin cancers and especially suitable for skin cancer that is in an area where it is important to preserve healthy tissue for a necessary functional and cosmetic result. It is also used to treat cancer that was removed previously and has come back, cancer that Is located near scar tissue, cancer that does not have clearly defined edges, and cancer that is growing rapidly or uncontrollably.

10) What kind of physician can perform Mohs surgery?

Most Mohs surgeons are board-certified dermatologists. And to become a Mohs surgeon, they have undergone a formal post-residency fellowship training in Mohs surgery at a major university hospital for one to two years.
