What is Mohs Surgery?
Mohs Surgery, also known as Mohs micrographic surgery, is a highly specialized technique used to treat
skin cancer. Named after Dr. Frederic E. Mohs, this procedure aims to remove cancerous tissues while preserving as much healthy tissue as possible. It is most commonly used for treating basal cell carcinoma and squamous cell carcinoma, the two most prevalent forms of skin cancer.
How Does Mohs Surgery Work?
Mohs surgery is performed in stages. Initially, the visible tumor is removed, and the tissue is examined under a microscope. If cancer cells are still present, additional layers are removed and examined until no cancer cells remain. This meticulous process ensures complete cancer removal while minimizing the loss of healthy tissue.
High Cure Rate: Mohs surgery has a cure rate of up to 99% for primary basal and squamous cell carcinomas.
Tissue Preservation: By targeting only cancerous cells, Mohs surgery conserves more healthy tissue, which is particularly important in cosmetically sensitive areas.
Immediate Results: The surgical team can immediately determine if all cancerous cells have been removed, reducing the need for additional treatments.
Have a high risk of recurrence.
Are located in areas where preserving healthy tissue is crucial, such as the face, ears, hands, and genitals.
Have borders that are hard to define.
Are large or aggressive.
Preparation: The area around the tumor is cleaned and numbed.
Removal: The visible part of the tumor is excised.
Examination: The tissue is processed and examined under a microscope.
Additional Stages: If cancer cells are detected, additional layers are removed and examined until no cancer cells remain.
Reconstruction: Once the cancer is completely removed, the wound is repaired. This may involve simple suturing or more complex reconstructive techniques, depending on the size and location of the excision.
Recovery and Aftercare
Recovery from Mohs surgery is typically straightforward. Patients may experience some swelling, redness, and minor discomfort, which can be managed with over-the-counter pain medications. It's essential to follow post-operative care instructions to ensure proper healing and minimize the risk of infection. Most patients can return to normal activities within a few days.Risks and Complications
While Mohs surgery is generally safe, it does carry some risks, including: Bleeding
Infection
Scarring
Nerve damage (rare)
It’s important to discuss these risks with your healthcare provider before undergoing the procedure.
Conclusion
Mohs surgery is a highly effective treatment for certain types of skin cancer, offering the highest cure rates and the best cosmetic outcomes. By understanding the procedure, its benefits, and potential risks, patients can make informed decisions about their treatment options. If you have been diagnosed with skin cancer, consult with a specialized dermatologist to determine if Mohs surgery is the right choice for you.
