皮肤癌

METHODS: A summary was performed of the existing literature regarding experience with retinoid chemoprevention for skin cancer in organ transplant patients.

执行现有文献摘要中所运用的方法（该文献是关于应用阿维 A 化学预防器官移植受者皮肤癌的文献）。

A triatomic molecule of oxygen; a natural constituent of the atmosphere, with the highest concentrations in the ozone layer or stratosphere; it is found at a level between 15 and 30 km above the Earth, which prevents harmful ultraviolet B radiation, which causes skin cancer and threatens plant life, from reaching the ground.

中文解释=具有三个氧原子的分子；是大气的天然组成成分，主要集中在臭氧层或同温层中；在地表15~30公里以上的高度，能防止引起皮肤癌和危害植物生长的有害紫外线B辐射线到达地表。

Apart from being responsible for up to 70% of ageing, UVA exposure is now known to be a major cause of skin cancer.

除了负责高达70 ％的老龄化，紫外线照射是目前已知的一个主要原因是皮肤癌。

You typically do not see the immediate effects of UV-A rays, but they are the chief culprit behind photo-aging and wrinkling in addition to actinic keratoses, a pre-cancerous skin condition.

通常你看不到即时效果紫外线的照射，但他们后面的罪魁祸首光老化起皱除了光化角化症，先决条件皮肤癌。

Although the variability in compliancewith posttreatment tretinoin and sunscreen use is another limitationof the study, the researchers report,"We do not believe that any significant differencein posttreatment regimen adherence existed among the 3 studyarms or biased our results for actinic keratoses reduction or nonmelanoma skin cancer development."

虽然治疗后使用Tretinoin和防晒霜的变数是本研究的另一个限制，作者报告指出，我们不认为在三个研究组的治疗后处方中有任何显著差异，也不认为对我们的减少光化性角化病和预防非黑色素皮肤癌结果有任何偏见。

Reporting in the August issue of the Archives of Dermatology , Dr. Swetter and her team present the findings of their randomized prospective 5-year trial. Looking at patients with previous nonmelanoma skin cancer and severe sun damage, the group studied the effect of facial resurfacing for the treatment of actinic keratoses and prophylaxis againstnew primary basal- and squamous-cell carcinomas.

该报告登载於八月版的皮肤医学档案期刊，Swetter医师和她的团队报告此一随机前溯的五年试验研究发现，著眼於非黑色素皮肤癌和严重晒伤病患，研究脸部皮肤重建整形治疗光化性角化病，和预防初发基础细胞癌以及鳞状细胞癌的效果。

Freckles, age spots, spider veins on the face, rough and leathery skin, fine wrinkles that disappear when stretched, loose skin, a blotchy complexion, actinic keratoses (thick wart-like, rough, reddish patches of skin), and skin cancer can all be traced to sun exposure.

雀斑、色斑、脸上的红血丝、粗糙皮革化的皮肤、小细纹、皮肤松弛、肤色不匀、日光性角化病(一种厚伽，粗糙，鳞片状的皮肤病)，以及皮肤癌都能在阳光照射上找到原因。

Scientists are excited about a vitamin again. But unlike fads that sizzled and fizzled, the evidence this time is strong and keeps growing. If it bears out, it will challenge one of medicine's most fundamental beliefs: that people need to coat themselves with sunscreen whenever they're in the sun. Doing that may actually contribute to far more cancer deaths than it prevents, some researchers think.

美国研究人员近日发现，晒太阳可能有防治癌症的功效，因为越来越多的证据表明被称为&日照维生素&的维生素D对预防和治疗淋巴瘤、前列腺癌、肺癌、甚至皮肤癌等多种癌症有重要作用，尤其在防治结肠癌方面的表现最为突出。

With recent worries about global warming, holes in the ozone layer, and skin cancer, many people are slathering up on sun block when they go outside for any length of time.
