Basics of Skin Cancer
Skin Cancer occurs when mutations occur in the DNA of skin cells. The mutations cause the cells to grow out of control and form masses of cancer cells.
Skin Cancer is the most common of all cancers.
The Causes
The Symptoms
Spots, sores, lumps, blemishes or markings on the skin that change in shape, size or color
Skin may become reddish, crusty or scaly
Skin may ooze, bleed or swell or may feel painful, scratchy or tender.

How many people die each year?
Skin cancer is the most common form of cancer in the United States. The following statistics refer to melanomas of the skin. In 2011 70,853 people in the United States were diagnosed with melanomas of the skin, including 41,573 men and 29,280 women.12,212 people in the United States died from melanomas of the skin, including 8,241 men and 3,971 women.
These rates are based on the survival rates of 60,000 people diagnosed patients
Simple excision: The tumor is cut from the skin along with some of the normal skin around it.
Shave excision: The abnormal area is shaved off the surface of the skin with a small blade
Cryosurgery: A treatment that uses an instrument to freeze and destroy abnormal tissue
Laser surgery: A surgical procedure that uses a laser beam as a knife to make bloodless cuts in tissue
Dermabrasion: Removal of the top layer of skin using a rotating wheel or small particles to rub away skin cells.

Stage IA: The 5-year survival rate is around 97%. The 10-year survival is around 95%.

Stage IB: The 5-year survival rate is around 92%. The 10-year survival is around 86%.

Stage IIA: The 5-year survival rate is around 81%. The 10-year survival is around 67%.

Stage IIB: The 5-year survival rate is around 70%. The 10-year survival is around 57%.

Stage IIC: The 5-year survival rate is around 53%. The 10-year survival is around 40%.

Stage IIIA: The 5-year survival rate is around 78%. The 10-year survival is around 68%.*

Stage IIIB: The 5-year survival rate is around 59%. The 10-year survival is around 43%.

Stage IIIC: The 5-year survival rate is around 40%. The 10-year survival is around 24%.

Stage IV: The 5-year survival rate is about 15% to 20%. The 10-year survival is about 10% to 15%. The outlook is better if the spread is only to distant parts of the skin or distant lymph nodes rather than to other organs, and if the blood level of lactate dehydrogenase (LDH) is normal.
