Slide 1 of 34:    Cancer is the No.   2 cause of death in the US, second only to heart disease.    It fundamentally affects the way our cells grow and divide,   changing them in perverse ways. All cancer is a result of damage   or genetic mutations in our DNA. The nasty, debilitating class of   diseases spreads through a body like an invading army, as toxic   cells grow relentlessly into unruly tumors.    Some cases of cancer are out of our control, determined by   genetic defects and predispositions passed down from one   generation to the next, or spurred by genetic changes we undergo   through our lifetime.    But we also know that breathing in certain substances, eating   specific things, and even using some kinds of plastics ups the   risk of developing some deadly cancers.    Here are some known carcinogens (cancer-causers), as well as a   few more things scientists are zeroing in on as prime suspects.

癌症是美国的第二大死因(No. 2 cause of death in the U.S),仅次于心脏病。

它从根本上影响我们的细胞生长和分裂的方式,以不正当的方式改变它们。 所有癌症都是我们DNA中的损伤或基因突变的结果。这种令人讨厌的,令人衰弱的疾病像入侵军队一样在身体传播,因为毒细胞能无情地成长为不规则的肿瘤。



Slide 2 of 34:    Scientists now know that eating too much sweet stuff can not only   lead to diabetes, but actively   damage your cells and increase your risk of developing   cancer.    But that's not all.    New research suggests that sugar may fuel tumor growth in the   body - because cancer loves to use sugar as fuel.    "The hyperactive sugar consumption of cancerous cells leads to a   vicious cycle of continued stimulation of cancer development and   growth" Johan Thevelein, a Belgian molecular biologist,    said in October after the release of his study.    Scientists say that the groundbreaking research gives us a better   understanding of how sugar and cancer interact and that it could   one day help create targeted diet strategies for patients.    NOW WATCH:    The differences that matter between Splenda, Equal, Sweet'N Low,   and sugar >>



新的研究表明,糖可能会促进体内肿瘤的生长 - 因为癌症喜欢用糖作为燃料。

“糖的消耗导致癌症细胞过度活跃,持续刺激癌症生长。”比利时分子生物学家约翰·夫莱因(Johan Thevelein)在去年10月发表他的研究后表示。


Slide 3 of 34:    Any food that comes in a crinkly plastic wrapper, is industrially   sealed, and is designed to last for months without spoiling may   be a quick on-the-go fix for a hunger pang, but it's also most   likely increasing your risk of cancer.    Scientists in France recently    zeroed in on a link between people who eat more processed   foods and those who develop cancer.    They're not sure yet whether the problem is the shelf-stabilizing   ingredients, the plastic packaging, or some combination of the   two. And because their study was correlative, it's possible   there's some other hidden factor at work.    NOW WATCH:    I ate nothing but 'healthy' fast food for a week - here's what   happened >>




Slide 4 of 34:    Though the tobacco industry tried to cover this one up, we've   known for years that tobacco smoke has at least 70    cancer-causing chemicals inside.    And it's not just smokers who are affected - people who inhale   secondhand smoke can develop deadly forms of cancer too.    The    Centers for Disease Control and Prevention says: "Nonsmokers   who are exposed to secondhand smoke at home or at work increase   their risk of developing lung cancer by 20-30%."    People who chew their tobacco are at increased risk too.



并且不只是受影响的吸烟者 - 吸入二手烟的人也会患上致命的癌症。



Slide 5 of 34:    According to the Skin Cancer Foundation, people who use a tanning   bed before age 35 increase their   risk of developing melanoma by 75%.    Regular sun can hurt you too, so wearing protective clothing and   sunscreen and finding shade are good ideas if you're going to be   out in the sunshine for more   than 15 minutes.




Slide 6 of 34:    Some people work with cancer-causing substances daily.    Those at risk of coming in contact with cancer-causing substances   on the job include:    • Aluminum workers.    • Painters.    • Tar pavers, who come in contact with the carcinogen benzene.    • Rubber manufacturers.    • Hairdressers    who deal with dyes every day.    • Nail-salon workers    breathing in dangerous fumes.





Slide 7 of 34:    The International Agency for Research on Cancer classified   nighttime work as a probable   carcinogen in 2007. Scientists think working at night, and   working long hours into the darkness, can both mess with the   body's natural, circadian sleep and wake cycles.    The CDC has a full list   of occupational cancer hazards.



Slide 8 of 34:    Arsenic, a natural part of the Earth's crust, is toxic in   its inorganic form. It's often found in contaminated drinking   water in places like Bangladesh, or in spots where irrigation   systems for crops use arsenic water.    The World Health Organization says at least 140 million people in   50 countries drink water containing high levels of arsenic.    It's also one of the cancer-causing agents in tobacco.

砷是地壳的天然成分,其无机形态,而且有毒。 在孟加拉国这样农作物灌溉系统使用到砷水的地方,经常会发现饮用水被污染。




Slide 9 of 34:    Smoky meats from the grill may be tender and tasty, but they   probably also increase your risk of cancer. That's because the   muscle meats contain compounds called heterocyclic amines, or   HCAs, and polycyclic aromatic hydrocarbons, or PAHs.       According to the National Cancer Institute, when meats like   beef, poultry, or fish are cooked over a hot open flame or   pan-fried at high temperatures, the fat and juices they release   into the fire spark flames with the dangerous chemicals inside   that then cook into the meat we eat.    They're not positive that these chemicals cause cancer, but in   lab tests they have been found to change DNA in ways that might   increase the risk of cancer.

烤架上的烟熏肉可能既嫩又好吃,但它们也可能增加患癌症的风险。 这是因为肌肉中含有称为杂环胺或HCA的化合物,以及多环芳烃或多环芳烃。
