What is skin cancer
Skin cancer is the fastest growing type of cancer in the United States. Skin cancer represents the most commonly diagnosed malignancy. More than 1 million Americans will be diagnosed with skin cancer in 2007.
Skin cancer is a malignant growth on the skin (Uncontrolled proliferation of skin cells) which can have many causes. The cells of a cancerous growth originate from a single cell that reproduces uncontrollably, resulting in the formation of a tumor. Skin cancer generally develops in the epidermis (the outermost layer of skin), so a tumor is usually clearly visible. This makes most skin cancers detectable in the early stages. Skin cancer is often subdivided into either melanoma or non-melanoma. Each of the three common types of skin cancer, is named after the type of skin cell from which it arises. Melanoma is a tumor arising from a skin cell capable of making the pigment melanin (a melanocyte). Non-melanoma skin cancer most often originates from the external skin surface as a squamous cell carcinoma or a basal cell carcinoma. Surgical removal is the treatment of choice, and sun protection has been shown to dramatically reduce the incidence of this illness. Cancers caused by UV exposure may be prevented by avoiding exposure to sunlight or other UV sources, wearing sun-protective clothes, and using a broad-spectrum sun screen.

Epidemiology of Skin Cancer
Skin cancer ---> Skin cancer Statistics
Skin Cancers are the most commonly diagnosed malignant tumors in the United States, with an incidence of approximately 1.4 million new cases annually. One in five Americans born in 2004 will be diagnosed with skin cancer in their lifetime. More than half of all cancers diagnosed in the United States are skin cancers. The most common skin cancer types are basal and squamous cell carcinoma (BCC and SCC). Melanoma accounts for 4% of skin cancer diagnoses but accounts for 75% of skin cancer deaths, with 7,910 deaths due to melanoma in 2004, or about one every hour. Approximately 95,880 new cases of melanoma will be diagnosed in the United States in 2004: 40,780 in situ and 55,100 invasive (29,900 men and 25,200 women). This represents a 4% increase in new cases of melanoma from 2003. The incidence of melanoma has more than tripled among Caucasians between 1980 and 2003. Invasive melanoma is the fifth most common cancer in men, seventh most common cancer in women, and the most common form of cancer of any type in women between 25 and 29 years of age. The early diagnosis and surgical treatment of these skin cancers can be curative.
