Skin cancer is the most common form of cancer. Treatment selection is shaped by certain factors, such as the type, location, size, and personal health factors. A clear understanding of Mohs surgery and other medically recognized treatment options can help patients work with professionals and identify a suitable plan.
What Is Skin Cancer?
Skin cancer occurs when abnormal skin cells multiply uncontrollably. This process often starts after cumulative exposure to ultraviolet (UV) radiation from sunlight or indoor tanning devices, which causes DNA changes in skin cells. There are three commonly diagnosed types of cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma.
Basal cell carcinoma is the most prevalent and usually appears on areas exposed to the sun, such as the head or neck. These lesions may look like flesh-colored bumps or pink patches, and they generally develop slowly. Squamous cell carcinoma is also common on sun-exposed skin and may appear as firm, red nodules or flat patches. Melanoma is known for a higher risk of spreading and can develop in a pre-existing mole.
What Is Mohs Surgery?
Mohs surgery is a highly detailed surgical method for removing certain types of skin cancer. The process involves the surgeon excising the visible tumor, removing a minimal margin of surrounding tissue along with it. This tissue is immediately prepared for examination, with horizontal sections carefully mapped and reviewed under a microscope on site.
If microscopic analysis reveals areas where skin cancer remains, the surgeon notes the corresponding section and removes another thin layer only from that area. This stepwise pattern continues until microscopic evaluation finds no evidence of cancerous cells in the peripheral or deep margins.
This approach limits the removal of healthy surrounding tissue and is frequently used for tumors on sensitive or cosmetically significant areas, including the face or hands. The technique’s accuracy in assessing tissue margins can minimize the likelihood of residual tumor. Mohs surgery is performed using local anesthesia in an outpatient setting, which allows patients to return home the same day.
What Are Other Treatment Options?
A variety of other treatments are recognized in the management of skin cancer. Surgical excision involves removing the cancer and an area of normal-looking skin around it. The tissue is sent to a laboratory for microscopic examination, which confirms whether the entire tumor was removed. This method is widely used for treating skin cancer, especially when Mohs surgery is not indicated or necessary.
Radiation Therapy
Radiation therapy employs targeted high-energy rays, such as X-rays, to destroy cancer cells. It can be chosen when surgery might be less feasible or where the tumor location makes surgery more complicated. Radiation is also used for certain recurrent cancers or to address areas with broader involvement.
Topical Chemotherapy and Immunotherapy
Some non-melanoma skin cancers limited to the surface of the skin may be treated using solutions applied directly to the affected area. Topical chemotherapy medications act to eliminate cancer cells. Topical immunotherapy stimulates local immune response to identify and attack abnormal growths.
Confer With a Skin Specialist
Selecting the appropriate approach for skin cancer requires a thorough assessment by a medical professional with expertise in dermatology. Medical teams can evaluate the specifics of each case and guide patients through treatment. Professional support is a key resource throughout treatment, helping patients and families feel reassured and fully informed about their care pathway.
