Mohs surgery is the most advanced technique in removing and treating skin cancer. This surgery is performed by removing thin layers of cancerous skin progressively and examining each layer until only cancer free skin tissue is left. Today, Mohs surgery has come to be accepted as the single most effective technique for removing Basal Cell Carcinoma and Squamous Cell Carcinoma (BCCs and SCCs), the two most common skin cancers. 

Mohs surgery preserves the greatest amount of healthy tissue while also completely removing cancer cells. Mohs Surgery allows us to verify that all cancer cells have been removed, increasing the outcome of a cure, while reducing the need for another surgery or treatment. 

Cure rates for BCC and SCC are an unparalleled 98% or higher with Mohs, significantly better than the rates for a standard excision or any other accepted skin cancer removal method. Unlike other skin cancer procedures where a random sample of the clear margin is examined, by undergoing Mohs surgery, patients get a comprehensive examination of the surgical margin, providing more accurate results. 

In the past this type of skin removal surgery was performed by a doctor creating an excision of the cancer tissues, and at the same time removing the surrounding healthy skin. Now with Mohs surgery, there is much less damage to the surrounding healthy skin, which means better results.  

Mohs surgery is an excellent treatment for skin cancers that have a risk of reoccurrence, are in a more sensitive areas such as the eyes, nose, ears, on hands or feet, and genitals, or for the more aggressive forms of skin cancers, melanomas and carcinomas.  

One of the great things about Mohs surgery is that you most likely won’t leave your appointment until all the skin cancer is removed. You will know your results right away, as the doctor will be checking every layer of tissue as they’re removed. This is performed as an outpatient procedure, and you will be able to head home the same day knowing that all cancerous cells have been removed. 

The procedure is performed under local anaesthesia and involves four basic steps: 

1. Surgical removal of tissue
2. Mapping the piece of tissue and then freezing and cutting it 
3. Interpretation of tissue under the microscope slides
4. Reconstruction of the area from where the tissue has been removed.

As the surgery is a combination of several specialised stages, it requires the skills and expertise of a team of qualified professionals — a dermatologist, a pathologist and a plastic surgeon.

Frequently Asked Questions

Also known as Mohs micrographic surgery, this treatment developed by Dr. Frederic Mohs is a highly specialised and precise outpatient treatment for skin cancer in which the cancer is removed in stages, one tissue layer at a time. Once a tissue layer is removed, it is then examined by a Mohs technician and doctor under a microscope so that the origin of the cancer can be identified and mapped.

If cancer cells are detected, an additional tissue layer is removed only in areas where the cancer is still present, leaving normal skin intact. Once the cancer has been removed, the Mohs surgeon will explain options for repair of the wound, including natural healing (granulation), suturing the wound together by way of a usual side to side closure, or using a skin flap or graft and reconstruction.

Your doctor will advise you that this procedure will take around half a day as it involves removing the entire cancer in one appointment, removing tissue, analysing it until all the cancer has been removed and reconstruction of the area following removal of the cancer which can take up to one or two hours depending on the size and complexity of the area.

Mohs surgery is highly successful, and results are as high as 99 percent for the removal of a basal cell skin cancer and 95 percent for squamous cell skin cancer and other recurrent cancers.

Mohs Surgery is very accurate.
Mohs surgery is incredibly accurate, as a surgeon will be removing the skin layer by layer off the cancer site. The surgeon will then examine each layer under a microscope to determine if any cancer cells remain in the tissue. The process of removal and inspection under the microscope is repeated until all cancer cell tissue has been removed.

Better Long term Cosmetic Results with Mohs Surgery.
Through this method, the surgeon can remove the entire cancer tissue without damaging the surrounding healthy skin tissue. This process keeps the scarring minimal and promotes quicker healing. Approximately 80% of patients will only need to have one layer of skin removed to remove the cancerous tissue. As the recurrence rate is lower than any other technique Mohs can overall give the best long term cosmetic result

Mohs surgery can be used to remove many common skin cancers such as basal cell carcinomas and squamous cell cancers. Your doctor may have referred you for this treatment if:

- The cancer you have is in an area such as; the eyelids, nose, ears, lips, fingers or toes

- Your skin cancer was treated in the past and has returned

- The scar tissue exists in the vicinity of the skin cancer

- The skin cancer is large

- The edges of the skin cancer cannot be clearly defined

- Your skin cancer is growing rapidly

Mohs surgery will preserve as much healthy skin as possible and once the cancer is removed, your doctor or surgeon will ensure reconstruction to the area leaves as minimal scarring as possible. Any scarring will improve over time but can take around a year to completely heal. Scar injections and other treatments such as laser resurfacing are also available at Cadogan Clinic so we can you an entire portfolio of treatments around your Mohs procedure.

Your doctor or surgeon will advise you on aftercare at consultation and again immediately after your surgery, you will be asked to visit following your reconstruction to ensure your healing is optimum. Your dermatologist plays an important role in helping you to maintain disease-free skin so regular check-ups can be arranged for the future.

Mohs surgery costs can vary depending on the size and complexity of the treatment required – this will usually be established during your initial consultation. Treatment usually starts from £3000, however every case is different and the best way to receive an estimate for your case is to book in a consultation.

Mohs surgery is nearly painless. Aside from the initial injection of anaesthetic to numb the area, patients will feel very little pain either during of after the surgery. Most clients have a pain level of 0 out of 10 after 24 hours, and any minor pain experienced can usually be handled with paracetamol or an over the counter pain medicine.
