Mohs Surgery

Skin cancer is one of the most common cancers in the United States, but early and precise treatment leads to excellent outcomes. At ALLUSTRA DERMATOLOGY, located in the Heights and Memorial City in Houston, Texas, Brundha Balaraman, MD, offers expert evaluation and treatment for skin cancer, including Mohs micrographic surgery. This highly specialized procedure is designed to remove cancerous tissue while preserving as much healthy skin as possible. If you’ve been diagnosed with basal cell or squamous cell carcinoma, schedule a consultation by phone or online to discuss your treatment options.

What is Mohs surgery?

Mohs surgery, also called Mohs micrographic surgery, is a precise surgical technique used to treat certain types of skin cancer.

During the procedure, thin layers of cancer-containing skin are removed and examined under a microscope in real time. Each layer is evaluated immediately to check for remaining cancer cells. The process is repeated until no cancer cells are detected. 

Mohs surgery is often performed in a single visit under local anesthesia.

What types of skin cancer does Mohs surgery treat?

Mohs surgery is most commonly used to treat Basal cell carcinoma (BCC) and Squamous cell carcinoma (SCC). It may also be used for certain other less common skin cancers, depending on location and risk factors.

What is basal cell carcinoma?

Basal cell carcinoma is the most common type of skin cancer. It develops in the basal cells, which are located in the lower part of the epidermis (the outer layer of skin).

Basal cell carcinoma often appears as:

• A pearly or shiny bump
• A pink or red patch
• A sore that doesn’t heal
• A lesion that bleeds easily

BCC grows slowly and rarely spreads to other parts of the body. However, if left untreated, it can grow deeper into the skin and surrounding tissues, causing local damage.

Mohs surgery is especially effective for basal cell carcinoma located on cosmetically sensitive areas such as the face, nose, ears, and scalp.

What is squamous cell carcinoma?

Squamous cell carcinoma is the second most common type of skin cancer. It develops in the squamous cells, which make up most of the upper layer of the epidermis.

Squamous cell carcinoma may appear as:

• A firm red nodule
• A scaly, crusted patch
• A sore that doesn’t heal
• A growth that may bleed or become tender

Unlike basal cell carcinoma, squamous cell carcinoma has a slightly higher risk of spreading if not treated promptly. Early diagnosis and appropriate treatment are essential.

What can I expect during Mohs surgery?

Mohs surgery is performed in stages during a single visit. First, the area is numbed with local anesthesia. The visible tumor is removed along with a thin layer of surrounding tissue. That tissue is immediately processed and examined under a microscope.

If cancer cells are found at the margins, additional tissue is removed only from the areas where cancer remains. This process continues until the tissue is clear of cancer cells. Once the cancer is fully removed, your provider discusses repair options. You receive detailed aftercare instructions to support healing and minimize scarring.

Early evaluation is key. If you notice a new or changing skin lesion, schedule an appointment for a skin examination. Contact ALLUSTRA DERMATOLOGY by phone or online.
