Skin cancer is a condition in which malignant cell growth occurs in skin tissues. With more than 3 million new cases reported each year, skin cancer is one of the most prevalent types of cancerous disease in humans. However, it is important to emphasize that, for the most part, skin cancer is preventable and, with early detection, entirely treatable.
The principal causes behind the appearance of skin cancer are family history and exposure to the sun’s UV radiation. As such, the vast majority of skin cancers occur in people of light skin pigmentation, people who are older than 30 years old, and mainly in those individuals with an extensive history of sunburn and recreational sun exposure.
Therefore, the progression and prognosis of the disease will depend extensively on prevention and early detection.
There are three main types of skin cancer:
