Among the several harmful and serious diseases appeared in the half secondary millenium that affect and still affecting the health of human being,there was one called skin cancer consisting on the infection and the destruction of the cutaneous system's protection of human body that could be leading to fatal death. Many researchs have been done for about what it is causing this pathology of infection of both the dermis and the epidermis of the parts of the umminity's system of skin body. After a many years of researchs,the worldwide panel of medical research's council identified and repertoried the causes and eventually the symptoms for the the diagnostic of contamination of the skin's body. The most causes and well known by the concerned medical experts , is the attack of UV's sunrays on the skin body.The spectrum of the ultra violet(UV) acts a concentred radiation from the sun rayonment resulting on the continual dynamic boiling of the sun. There are both types of UV called respectivelly UV(A)and UV(B).The medical research panel taught at first that the UVB is the principal responsible causing skin cancer,but at the researchs are going on,they dicovered that also the UVA is involved. These UV attack and damage the different functions of cell's skin assuming the role of protection and at the end annihilate them for the creation of cell's cancerThe.skin is constituted by a substance called MELANIN which its function is to absorb the UV, but when the spectrum is very intense, the melanin is unable to meet its protection duty against sunray's,situation leading to the degradation of cell's skin and the apparition of skin's cancer.

In effect,the evolution of contamination of these cell's skin cause the eclosion of cell's cancer at the preliminary stade and progress till the total infection and that respectvelly to the umminity's system of human body. Other factor to be contaminated by skin cancer is also through the heredidary, the parents whom their genes become abnormal caused by this affection could transmit the disease to their children

There are also indirect risks and causes acting as a catalyst for a person susceptible to contract this malign affection to skin body like smoking, diet and family story and other thing may be not known at the moment as the researchs are on way like many others diseases under the scope of deeply investigation. Actually, the risk of getting skin cancer is greater than before in view of the reduction of the ozone's enveloppe which its role is to regulate the level of UVscreened by this protective layer surronding the earth's atmosphere.

The amount of UV hitting the earth and in which we are exposed will be higher and much more dangerous concerning the risk to get skin cancer if some sreened UV protective material would not be developped for the ultimate prevention.

IKnowing this dangerous contamination. abouth the risks can guide you to the appropriate actions and measures should be taken to evoid this harmful death pain.
