Mohs surgery

 involves removing the visible skin cancer and layers of adjacent skin and soft tissue to facilitate microscopic examination of the excised tissue. Meticulous maps are created to follow tumor extensions, and excisions are sequentially continued until no cancer cells are evident upon microscopic examination. The surgical wound is then repaired to preserve as much form and function as possible. Mohs micrographic surgery – developed in the 1930s by Dr. Frederic Mohs – offers the highest cure rates in the treatment of basal cell and squamous cell cancers of the skin.

Mohs surgery is the most effective treatment for basal cell and squamous cell carcinomas, and it also works much better than conventional treatments for a number of less common skin cancers. Cure rates for many types of skin cancers are 98-99 percent using Mohs surgery – significantly higher than with other treatment methods.

Since tissue is removed only until the cancer is no longer present, the Mohs surgical procedure minimizes the size of the surgical wound required for skin cancer treatment and reduces the size and appearance of the resulting surgical scar.

Dr. Byron Limmer is a leading expert in Mohs surgery who provides personalized, state-of-the-art care for his patients and is referred patients by physicians throughout South Texas.

"Dr. Limmer saved my life. He found my melanomas early, before they had spread. I’ve been going to him for years and can tell you that he’s a marvelous surgeon and a really good man.

I have a history of skin cancers after working outside in the sun my whole life. It’s been very important to my family and me that I get expert treatment from a doctor that truly cares about each and every one of his patients.

Dr. Limmer always takes his time with me and that means a lot. He’s removed several melanomas from my skin and I’m always so impressed with his work."
