Skin Cancer Risk

 Exposure to UV radiation from the sun will change the structure and composition of the skin, the loss of skin elasticity (elastosis) and thickening of the skin (keratoses). UVB radiation at the cellular level (membrane, protein and DNA), DNA damage which is the beginning of keratinosites and melanosites which in its development can be skin cancer. There are 3 types of skin cancer that can be distinguished namely Basal Cell Carcinoma (BCC), Squamos Cell Carcinoma (SCC) and Cutaneous Malignant Melanoma (CMM). Of the three types of cancer, the CMM is derived from pigment cells (melano-cytes) is a type of malignant tumor. While the BCC and SCC derived from keratinocytes, is a type of tumor is not malignant, 98% can be cured.

Characteristics of the population with the greatest risk of skin cancer is if you have moles (moles) a lot, with white spots and easily burned by the sun's rays are the type I and albino skin. Most skin cancers in the calf area, hands and neck with three types: nodular, superficial spreading lentigo and freckles. Of the third type, nodular type of the most dangerous because it is fast growing and fatal. incidence of skin cancer has increased every year. It is believed by environmental experts, because of the increase ultraviolet radiation from sun exposure due to ozone layer depletion in the stratosphere. 

Epidemiological studies, which have been made, obtained information that the type of basal cell carcinoma (BCC) is common in Caucasian whites (generally around 90 cases per 105 population per year in northwest Europe), approximately 15 cases per 105 population per year for this type of SCC and 10 cases per 105 population per year for this type of CMM. The number of cases for residents of Australia of 9.8 per 100,000 (men) and 5.0 per 100,000 (women) per year for skin cancer type CMM with the percentage of mortality between 40-60%. Greatest risk of skin cancer for all skin types, is exposure to UV radiation in childhood. Therefore protect children from exposure to sunlight.
