It is estimated that over 1 million new cases of non-melanoma skin cancer occur annually. This number is growing significantly and thus it represents a growing public concern. It has been estimated that nearly half of all Americans who live to age 65 will develop skin cancer at least once.
The most common warning sign of skin cancer is a change in the appearance of the skin, such as a new growth or a sore that will not heal and persists for more than 2 months.
The three most common skin cancers, from the least to the most dangerous, include:
The two most common forms of skin cancer are basal cell carcinoma and squamous cell carcinoma. These are also often referred to by many as being non-melanoma skin cancer because of the familiarity of Melanoma. Melanoma is most often the most serious type of skin cancer and results in many deaths every year. Recent Presidential Nominee John McCain suffered from Melanoma but thankfully it was detected early enough to be properly treated. Melanoma can quickly metastasize and spread throughout the body.
