What Is Mohs Surgery?

Mohs is a procedure used to treat certain types of skin cancer. During Mohs surgery, the visible tumor and a thin layer of tissue around it is removed. The tissue is then checked under a microscope for the presence of cancer cells at all edges of the tumor. This process is repeated until no more cancer cells are seen. Mohs surgery removes as little normal tissue as possible. It is most often used to remove skin cancers on the scalp, face, lip, ear, neck, hands and feet. Also called Mohs micrographic surgery.

Why Is Mohs Surgery So Effective Against Skin Cancer?

Mohs surgery is considered one of the most effective treatments for many types of skin cancer because it combines surgical removal with immediate microscopic evaluation.

Surgeons can confirm complete cancer removal while preserving as much healthy tissue as possible. This results in:

  • High cure rates

  • Minimal removal of healthy tissue

  • Reduced likelihood of recurrence

  • Optimal cosmetic and functional outcomes

Its precision makes it especially valuable for cancers located in sensitive or highly visible areas.

The Critical Role of Mohs Technicians

The success of Mohs surgery depends not only on surgical skill, but also on the expertise behind the scenes.

After the surgeon removes the tissue, a Mohs technician carefully processes the specimen. The tissue is embedded, frozen in a cryostat, sectioned into ultra-thin layers, mounted onto slides, stained, and prepared for evaluation.

Accuracy at this stage is essential. The clarity and quality of each slide directly impact the surgeon’s ability to identify remaining cancer cells.

At Top Notch Mohs, we recognize that every slide represents a patient waiting for answers. Our commitment to precision, efficiency, and excellence supports surgeons in delivering the highest standard of skin cancer care.
