Basal-cell carcinoma
In the United States approximately 3 out of 10 caucasians develop a basal-cell carcinoma during their lifetime. This tumor accounts for approximately 70% of non-melanoma skin cancers. In 80 percent of all cases, basal-cell carcinoma affects the skin of head and neck. Furthermore, there appears to be an increase in the incidence of basal-cell cancer of the trunk in recent years.

The cure rate for this method, whether performed by a General Surgeon, Otolaryngologist, Head & Neck Surgeon, Plastic Surgeon, Maxillofacial Surgeon or dermatologist is totally dependent on the surgical margin. The narrower the free surgical margin (skin removed that is free of visible tumor) the higher the recurrence rate. If a 4 mm free surgical margin is obtained around a small tumor (less than 6mm), or a wider 6 mm free surgical margin is obtained around a larger tumor (greater than 6mm), the cure rate is very high—95% or better. However, for cosmetic reasons, many doctors take only very small surgical margins 1–2 mm, especially when operating on the face. In such a case, a pathology report indicating the margins are free of residual tumour is often inaccurate, and recurrence rates are much higher (up to 38%).
