What is Mohs Surgery?

Mohs surgery is a precise surgical technique used to treat certain types of skin cancer, including Basal Cell Carcinoma. It involves removing the cancer layer by layer and examining each layer under a microscope until no abnormal cells remain. This method allows for the highest possible cure rate while preserving as much healthy skin as possible. Below, you’ll find more detail on how the procedure is performed and the advantages it offers.

Understanding the Mohs Surgery Process and Its Benefits

How Mohs Surgery Works and Why It’s the Gold Standard

Mohs surgery offers a unique combination of precision, effectiveness, and tissue preservation. Below, we explain how the procedure is performed and the key benefits it provides for patients undergoing treatment with Mr. Tehrani.

Anaesthetic and Initial Removal

Mohs surgery is usually performed under local anaesthetic (an injection is used to numb the skin around the cancer).

In some cases, it may be carried out under general anaesthetic (with you asleep).

The skin cancer is then removed, but unlike conventional surgery, only a minimal margin of ‘normal looking’ skin is taken initially.

Tissue Processing and Slide Preparation

The wound is dressed with a sterile dressing, and you return to the ward area.

Mr Tehrani takes the skin specimen into the nearby Mohs lab.

The specimen is processed to produce microscope slides.

Mohs maps are drawn to track exactly where the skin cancer was removed from.

Microscopic Examination and Mapping

The slides are checked under a microscope to look for any remaining skin cancer.

BCCs can have extensions or ‘roots’ that aren’t visible to the eye but can be detected microscopically.

If cancer is still present, its location is marked on the Mohs map.

Mr Tehrani identifies where on the wound the remaining cancer is located.

Repeat Excision Until Clear

The skin is numbed again, and another thin layer is removed — only from the area where cancer remains.

The process of dressing, slide preparation, and microscopic checking is repeated.

This continues until the cancer is fully removed.

Wound Repair and Reconstruction Options

Once clear, the wound is repaired depending on its size, location, and shape

Options include: Simple closure (stitches), Local flap (moving in nearby skin), Skin grafting, More complex reconstructive techniques

In some cases, the wound may be left to heal naturally

Frequently Asked Questions

Below you’ll find answers to common questions about Mohs Surgery with Mr Tehrani.

What is Mohs surgery and how is it different from standard skin cancer surgery?

Mohs surgery removes skin cancer layer by layer while each layer is examined under a microscope. Unlike standard surgery, it allows for precise removal with minimal loss of healthy tissue, offering the highest cure rate for Basal Cell Carcinoma.

Why is Mohs surgery recommended for Basal Cell Carcinoma?

Mohs surgery is considered the gold standard for treating Basal Cell Carcinoma due to its 99% cure rate and ability to preserve surrounding healthy skin — especially important for facial or complex areas. Mr. Tehrani specialises in this technique.

Will I need separate appointments for removal and reconstruction?

In most clinics, yes — but Mr. Tehrani is dual-trained in both Mohs and Reconstructive Surgery, meaning he can often perform both the removal and reconstruction in the same appointment.

Is Mohs surgery painful or done under general anaesthetic?

Mohs surgery is usually performed under local anaesthetic, making the area numb while you remain awake. General anaesthetic is only used in select cases depending on the patient and tumour location.

What happens if the cancer is not fully removed in one stage?

If any cancer cells are seen under the microscope, only the area where they remain is re-treated. This process is repeated until the skin is clear — ensuring complete removal with maximum tissue preservation.
