Talk the ultraviolet ray project light upon and the relation of the skin cancer

There are a lot of things in the daily life all emphasizing in our anti-cancers rules moderation then can, not proper surfeit.Suddenly and violently bask to the sunlight, take a sunbathe the absorption that can stimulate body to the vitamin D in principle, make the skeleton be getting stronger and healthy.But, too much expose under the ultraviolet ray in the sunlight, can make the skin cell's creation mutate, formation skin cancer.As early as 1890's, have already had a report to point out that the ultraviolet ray has something to do with the occurrence of the skin cancer to fasten, at 1906, have cultural heritage more to concretely state that some persons are specially easy to produce a skin cancer because of exposing under the ultraviolet ray.Afterward confirm in the animal experiment that the ultraviolet ray irradiation can cause a skin cancer in 1928.Discover that the ultraviolet ray wave-length's scope in 290~320 mms is next to more easily produce cancer-causing effect under the further science study.This text hopes with the easily understood study and make everyone understand the relation between skin cancer and ultraviolet ray more.



What person easily take place a skin cancer?From standpoint but speech of Epidemiology, the skin is easily project light upon by the sun but produce reaction(burn) and the skin essence is more meticulous, the hair is rarely seen, and the human race of blue eyes most easily contracts a skin cancer.The incidence rate of the people skin cancer, compare with Euro-American white man, don't calculate Gao.Its reason has something to do with the yellow race person's skin dye to fasten, it can reduce the absorption of ultraviolet ray, and therefore the incidence rate of skin cancer be lower.



Does the where more and easily take place a skin cancer?From the observation of Epidemiology under, to white man, higher in place ratio's incidence rate in its skin cancer of the high degree of latitude place of the Earth equator.In addition make the ultraviolet ray easily and directly project light upon exactly because of the defection and damage of the ozone layer in the atmosphere noodles, people very and easily expose under the ultraviolet ray, certainly former alter skin cancer.



The ultraviolet ray causes the machine of skin cancer to turn to have two kinds of parlances:While only turning DNA inside the cell of the function change for the ultraviolet ray;Moreover a kind of parlance is the immunity function that the ultraviolet ray projects light upon convertibility body.When the ultraviolet ray is absorb by the DNA after, result in hurt of DNA, produce so-called"Mi Ding two measure a body", this for cause the cell become sex of the biggest machine turn and the skin cancer also therefore takes place.The patient who has already grown special physical endowment, call"apply color stem a skin cancer"(Xeroderma pigmentosum), the its body skin cell lacks a repair and cleans the ultraviolet ray projects light upon the ability of damaged and output"Mi Ding two quantity body", so easiest skin cancer happen.Influence the observation of immunity dint in the ultraviolet ray can include following 3:00:(1)Break the structure of live and lymphoid ball antigen;(2)Make some antigen formation processes be influence;(3)Produce to suppress cell to make the ultraviolet ray cancer-causing process alter occurrence.



At clinical up, the skin cancer can is divided into two major types:While doing evil sex melanin lump, one is a non- melanin lump.The former compares to have nothing to do with ultraviolet ray influence.The non- melanin lump mainly includes cancer and the scale form top form cell of the base cell cancer.Both all have with ultraviolet ray irradiation near concern.This kind of detection of skin cancer is also not that difficult and the majority all can discover in early days.Therefore, the cure rate can be up to 90% above.The people at living habit aspect, less go to the sea beach suddenly and violently insolate in the strong sun underneath, the southern region people go out to also often support a parasol, reduce direct irradiation of be subjected to the ultraviolet ray and plus the yellow race person's skin dye inborn up had advantage, no wonder that the incidence rate of skin cancer doesn't show Zhao.
