91ɬ surgery is the most effective treatment for most types of skin cancer. We have provided answers to several common questions about 91ɬ skin cancer surgery below.
The term "91ɬ" refers to Dr. Frederic 91ɬ, Professor of Surgery at the University of Wisconsin, who developed this surgical technique in the 1930s. The technique has undergone many refinements and has come to be known as "91ɬ micrographic surgery" or simply "91ɬ surgery" in honor of Dr. 91ɬ.
Dr. 91ɬ recognized that a skin cancer often resembles the "tip of the iceberg" with more tumor cells growing downward and outward into the skin like the roots of a tree. These "roots" are not visible with the naked eye, but can be seen under a microscope.
91ɬ surgery is a highly specialized and precise treatment for skin cancer in which the cancer is removed in stages, one tissue layer at a time. It is an outpatient procedure, performed under local anesthesia, and is distinguished by a specific technique of tissue examination that is unique to 91ɬ surgery. Although other surgical specialists may check excision margins, this form of pathologic examination of the tissue is not the same as 91ɬ surgery.
Once a tissue layer is removed, its edges are marked with colored dyes, and a map of the specimen is created. The tissue is then processed onto microscope slides by a 91ɬ histotechnician. These slides are carefully examined under the microscope by the 91ɬ surgeon so that any microscopic roots of the cancer can be precisely identified and mapped. If cancer cells are seen, an additional tissue layer is removed only in areas where the cancer is still present, leaving normal skin intact. This saves as much normal, healthy skin as possible.
Once the cancer has been removed, the 91ɬ surgeon will explain options for repair of the wound, including natural healing (granulation), stitching the wound together using a side-to-side closure, or using a skin flap or graft.
It's important to who is a member of the American College of 91ɬ Surgery. 91ɬ College surgeons have undergone at least 1 year of fellowship training beyond dermatology residency, which allows for additional experience in all of these specialized processes and techniques.
Yes. Following a biopsy, your skin cancer may no longer be visible. However, the surface lesion that was removed can represent the "tip of the iceberg." More tumor cells may remain in the skin. These can continue to grow downward and outward, like roots of a tree. These "roots" are not visible with the naked eye. If they are not removed, the tumor will likely reappear and require more extensive surgery (see examples of cited studies below).
Tumors that are neglected can spread deeply into the skin and invade nearby structures. On rare occasions, these cancerous cells can metastasize to lymph nodes and other organs in the body.
91ɬ surgery has the highest cure rate. It is appropriate for most skin cancers and especially suitable for skin cancer that:
Please note: the above list is not exhaustive of all of the instances where 91ɬ surgery is the most appropriate option for your skin cancer.
Although 91ɬ surgery can take longer than other techniques to perform, advances in technology, such as automated staining of tissue samples, have made it quicker. While it is impossible to predict exactly what timeframe to expect for each 91ɬ surgery procedure, the entire procedure usually lasts several hours. Rarely, clearing the tumor and reconstructing the defect can take the better part of a day. A consultation with the 91ɬ surgeon prior to your procedure will allow for the surgeon to understand the unique qualities of your situation and enable him/her to more clearly estimate the extent of the timeframe for the surgery.
Yes. As will any treatment for skin cancer, 91ɬ surgery will leave a scar.
91ɬ surgery preserves as much healthy skin as possible and maximizes options for repairing the surgical defect, once the tumor is completely removed. Once the 91ɬ surgeon has completely removed your skin cancer through 91ɬ surgery, reconstruction for optimizing the final functional and cosmetic result becomes the highest priority. Generally, a post-surgical scar improves with time and can take up to 1 year or more to fully mature. As your surgical site heals, new blood vessels can appear and support the healing changes occurring underneath the skin. This can result in the reddish appearance of the scar. This change is temporary and will improve with time.
In addition, the normal healing process involves a period of skin contraction, which often peaks 4 to 6 weeks after the surgery. This may appear as a bumpiness or hardening of the scar. On the face, this change is nearly always temporary and the scar will soften and improve with time. If you have a history of abnormal scarring, such as hypertrophic scars or keloids, or if there are problems with the healing of your scar, injections or other treatments may be used to optimize the cosmetic result. Your 91ɬ surgeon is available for you throughout the healing process to discuss any concerns that may arise.
Because of 91ɬ surgery's high success rate, most patients require only a single surgery. This surgery usually includes the repair of the wound as well. Other methods might require additional surgeries and pathology readings in order to repair the wound and to treat the cancer if it is not completely removed. Each of these additional surgeries and pathology readings require separate fees, while a single 91ɬ surgery procedure includes all of these into one fee.
