Also called Mohs micrographic surgery
Used to treat skin cancer, this surgery has a unique benefit. During surgery, the surgeon can see where the cancer stops. This isn’t possible with other types of treatment for skin cancer.
The ability to see where the cancer stops gives Mohs (pronounced Moes) two important advantages:
- Mohs has a high cure rate.
- Mohs allows you to keep as much healthy skin as possible because the surgeon only removes the skin with cancer cells. This is especially important when skin cancer develops in an area with little tissue beneath (e.g., eyelid, ear, or hand).
What is it like to have Mohs surgery In Tustin, CA?
If you have Mohs surgery, you’ll see a doctor who is a trained Mohs surgeon. Most Mohs surgeons are dermatologists who have completed extensive training in Mohs surgery.
During Mohs surgery, most patients remain awake and alert. This means Mohs can safely be performed in a medical office or surgical suite. Only if extensive surgery is necessary would you be admitted to a hospital.
On the day of the surgery, your surgeon will first examine the area to be treated. You’ll then be prepped for surgery. This includes giving you an injection of anesthetic. This injection only numbs the area that will be operated on, so you’ll be awake during the surgery.
Once the anesthetic takes effect, the surgery can begin. The surgeon starts by first cutting out the visible skin cancer. Next, the surgeon removes a thin layer of surrounding skin. You’re then bandaged so that you can wait comfortably.
While you wait, the Mohs surgeon looks at the removed skin under a microscope. The surgeon is looking for cancer cells. If cancer cells are found, you’ll need another layer of skin removed.
This process of removing a thin layer of skin and looking at it under a microscope continues until the surgeon no longer sees cancer cells.
Once cancer cells are no longer seen, your surgeon will decide whether to treat your wound. Some wounds heal nicely without stitches. Others need stitches. To minimize the scar and help the area heal, some patients require a skin graft or other type of surgery.
If you need wound treatment, your Mohs surgeon may treat the wound that same day. Some patients with a large wound are referred to another surgeon for wound treatment.
When is Mohs surgery recommended?
- Is aggressive or large
- Appears in an area with little tissue beneath it (e.g., eyelid, nose, ear, scalp, genitals, hand, or foot)
- Was treated and has returned
Can Mohs treat melanoma?
Yes, dermatologists occasionally recommend Mohs for treating melanoma, the most serious type of skin cancer. Mohs is only used to treat an early melanoma, and it must be a type of melanoma called lentigo malignant melanoma. This type of melanoma stays close to the surface of the skin for a while.
When treating melanoma, the surgeon uses a modified type of Mohs surgery called slow Mohs. It’s called slow because the patient must wait longer for the results. It’s not possible for the surgeon to look at the removed skin and know right away whether it contains cancer cells. More time is needed.
If you have slow Mohs, the surgeon will remove the visible skin cancer and a bit of normal-looking skin around it. You’ll then be bandaged and sent home.
Most patients return the next day. It’s then that the patient learns whether more skin must be removed or the wound can be closed. Again, some wounds are left to heal on their own.
Who is Mohs recommend for?
No matter what type of skin cancer you have, Mohs is only recommended for certain patients. You must have one skin cancer or a few skin cancers that are very close together.
Mohs patients have good results
Having any type of surgery can be scary. If your dermatologist recommends Mohs, you can take comfort in knowing a few facts. Mohs has a high cure rate. Your surgeon will remove the least amount of skin needed to treat the cancer.
