ABSTRACT
Skin cancer is the most common type of cancer in the United States. There are more than
one million new cases diagnosed each year (1). Basal cell carcinoma (BCC) accounts for
more than 75% of the total number of skin cancers and squamous cell carcinoma (SCC)
constitutes 15%. Although both skin cancers can be treated effectively with topical
medication, radiation, or surgery, unchecked growth of BCC and SCC can lead to local
destruction and functional impairment. Advanced stages of SCC can spread and
metastasize. Melanoma (MM) only constitutes 5% of the skin cancers but is more deadly.
Over the last few decades, the incidence of MM has been increasing steadily. In 2008, it is
estimated that there will be 62,480 newly diagnosed MMs, and 8420 deaths from this
cancer (1). Currently, there is no effective cure for advanced disease; only early diagnosis
followed by prompt excision ensures a good prognosis.
