窄谱UVB光疗致癌吗？
我是新人我想问下窄谱uvb光疗，致癌几率高吗？这是国外网站上说的
What are the side effects and risks of narrowband UVB?
Narrow-band UVB can result in burning, just like sunlight and broadband UVB. Frequent emollients should be applied to burned skin, and if recommended by the therapist, topical steroids. It sometimes provokes polymorphous light eruption.
Long term exposure to ultraviolet radiation ultimately causes skin ageing and skin cancers. In theory, less UV exposure occurs because the patient is only exposed to therapeutic wavelengths. Although the risk from narrow-band UVB is unknown, research to date suggests it is no more risky than broadband UVB and probably less risky than photochemotherapy (PUVA).
这是百度百科上说的
致癌性
由于DNA的吸收峰值为265nm左右，而NB-UVB则避开了DNA的吸收峰，即不易引起DNA突变，从而降低其致癌性。然而 N B — U V B直 接诱导 T细胞凋亡 ， 并且使皮肤中顺式尿刊酸增 加， 导致 自然杀伤细胞活性降低， 降低机体的免疫监视 功能 ， 因而其致癌作用也可能 相应增 加。
我也想买个uvb治疗bb，看到论坛里效果这么好，但是上网查了一下，确实有副作用是吗？好纠结到底用不用呢？没有人回答下我吗？
光疗应用于治疗白白几十年，还没有一例因照光出现皮肤癌的，所以可以放心！ :L想太多了 想太多太多了
好吧
