Surgical treatments play an important role in managing different types of skin cancer. The appropriate procedure depends on the cancer type, size, location, depth, and whether it has spread. Common approaches include surgical excision, Mohs micrographic surgery, curettage and electrodesiccation, and lymph node surgery in selected cases. Understanding these procedures helps explain how doctors remove cancerous tissue, assess surgical margins.
Skin cancer develops when abnormal skin cells grow uncontrollably, often following damage from ultraviolet radiation. The main types include basal cell carcinoma, squamous cell carcinoma, and melanoma. Surgery is frequently used to remove localized skin cancers, although the procedure selected depends on the diagnosis, tumor characteristics, and individual health considerations. Some advanced or aggressive cancers may require surgery alongside other treatments.
Surgical procedures aim to remove cancerous tissue while preserving as much healthy surrounding skin as possible. Doctors evaluate the tumor's location, size, depth, and risk of recurrence before recommending a specific technique.
Surgical excision: The surgeon removes the visible tumor along with a margin of surrounding tissue. A laboratory examines the removed tissue to determine whether the edges are free of cancer cells. This approach is commonly used for melanoma and many basal cell and squamous cell carcinomas.
Mohs micrographic surgery: The surgeon removes thin layers of tissue and examines them under a microscope during the procedure. Additional layers are removed where cancer cells remain. Mohs surgery is particularly useful for certain skin cancers in areas where preserving healthy tissue is important, such as the nose, eyelids, and ears.
Curettage and electrodesiccation: A doctor scrapes away selected superficial skin cancers using a curette and may apply an electrical instrument to destroy remaining abnormal tissue. This method may be suitable for certain low-risk basal cell or squamous cell carcinomas, but it is not appropriate for every tumor.
Wide local excision: This procedure removes a melanoma or another selected skin cancer with a wider margin of surrounding tissue. The required margin depends on factors such as tumor thickness and the specific diagnosis.
Some skin cancers extend deeper into the skin or spread to nearby lymph nodes and other tissues. In these circumstances, surgery may involve more extensive tissue removal, lymph node assessment, or reconstructive procedures. The treatment plan depends on cancer staging, pathology findings, and the patient's overall condition.
Lymph node surgery: Sentinel lymph node biopsy may be recommended for selected melanomas to determine whether cancer has reached nearby lymph nodes. If lymph node involvement is identified, further evaluation and treatment are considered based on individual circumstances.
Reconstructive surgery: Following removal of a large tumor, surgeons may close the wound directly, use a skin graft, or move nearby tissue using a flap. Reconstruction aims to support healing and maintain function and appearance.
Surgery for recurrent cancer: Skin cancers that return after previous treatment may require additional excision or Mohs surgery, depending on their location and characteristics. Doctors also evaluate whether other treatments are appropriate.
Surgery combined with other treatments: Certain advanced melanomas and squamous cell carcinomas may require immunotherapy, targeted therapy, radiation, or other treatments in addition to surgery. The appropriate combination depends on the cancer type and stage.
Recovery varies according to the procedure, wound size, and location. Patients generally receive instructions on wound care, activity restrictions, and signs of infection. Follow-up appointments help monitor healing, review pathology results, and identify possible recurrence or new skin cancers. Regular skin examinations and protection from ultraviolet radiation are important parts of ongoing care.
The choice of surgical treatment should be based on a professional assessment of the cancer and the patient's individual circumstances. Understanding the available procedures can help patients discuss treatment goals, potential scarring, risks, and follow-up requirements with their healthcare team.
