癌症前期的

Cancer is uv's final result.shortwave radiant energy,especially from the uv b band,breaks the strandsof dna.enzymeswork constantly trearrange the dna into proper sequence.but with repeated uv exposure,the repair process may even-tually break down.then the mutantdna may produce a colony of cancer cells.but skin cancer may be avoided with a good dose of common sense.people with fair skin and blue eyes who burn easily stand the highest risk.special danger spots are the parts of the body most constantly exposed to the sun,such as the cheeks,nose,lower lip and the ears.people who have already developed precancerouslesionsor had one skin-cancer growth stand a greatly increased chance of developing others.

紫外线伤害的最终结果就是诱发癌症。短波辐射能量，特别是来自uv-b波段的辐射能量会破坏dna链。本来，酶能够按照适当的顺序来重新安排这些被打乱秩序的dna，但是持续暴露于紫外线下会让这一修复过程崩溃。到那时，变异的dna就会制造出大量的癌细胞。其实，只要运用一些常识。我们就能预防皮肤癌。浅肤色、蓝眼睛的人会轻易就被晒黑，因此他们患皮肤癌的风险就高。诸如脸颊、鼻子、下嘴唇和耳朵等长期暴露在阳光下的部位是皮肤癌的高发区域。那些已经受到癌症前期伤害或者是已经患过一次皮肤癌的人，极有可能再次患上皮肤癌。

然而，现在有研究表明，防晒霜已经能够提供对前期癌症的保护。
