The real origin is this: In every cell in your body, maybe 37 trillion of them, there is a copy of your genome, with about 3,235,000,000 pairs of nucleic acids arranged in two rows; most of them divide and create copies of themselves. Thus, throughout your lifetime, your body will silently make quadrillions, quintillions, probably sextillions and septillions of copies of base pairs. q0v世界播

真正的起源是这样的:在你身体里的每个细胞中,可能有37万亿个,都有一个你的基因组的副本,大约有323500万对核酸排列成两排;他们中的大多数分裂并创造了自己的副本。因此,在你的一生中,你的身体会默默地制造一千万亿、五亿分之一、可能六亿分之一和七亿分之一的碱基对拷贝。q0v世界播


Is it any wonder that this process isn’t perfect? q0v世界播

这个过程并不完美,这有什么奇怪的吗?q0v世界播


Sometimes, things go wrong. Sometimes it’s just chance: the copying machinery isn’t completely perfect, sometimes it slips up. Sometimes, it’s due to various risk factors: ionising radiation (as from sunlight or radon gas or nuclear fallout), or damage from cigarette smoking, or papillomaviruses, or maybe some dietary factors. There are dozens upon dozens, maybe hundreds of different cancers, quite distinct diseases although unified in the basic underlying principle: a change or copying error (either way, a mutation) causes the cells to fail to stop reproducing when they should: uncontrolled cell division. The cells fail to respond to the normal signals of “you’re done, die now” (apoptosis), and grow into a tumour. q0v世界播

有时候,事情会出错。有时只是偶然的:复印机器不是完全完美的,有时会出差错。有时,它是由各种危险因素造成的:电离辐射(如阳光、氡气或核尘埃),或吸烟造成的损害,或乳头瘤病毒,或者可能是一些饮食因素。有几十种不同的癌症,可能有数百种不同的癌症,尽管在基本的基本原理上是统一的:改变或复制错误(无论哪种方式,都是突变)会导致细胞在本应停止复制的时候停止复制:不受控制的细胞分裂。这些细胞对正常信号“你完了,现在就死”(凋亡)没有反应,并生长成肿瘤。q0v世界播


Cancer is not just a disease of humans. Rats get cancer. Dogs get cancer. Tasmanian devils get a really nasty kind of infectuous cancer that threatens their survival as a species. Sharks get cancer. q0v世界播

癌症不仅仅是人类的疾病。老鼠会得癌症。狗会得癌症。塔斯马尼亚魔鬼得了一种非常严重的传染性癌症,威胁到它们作为一个物种的生存。鲨鱼会得癌症。q0v世界播

On a side note, this makes the notion that shark cartilage can cure cancer because sharks are immune to it doubly idiotic. Not only is there no reason why eating an immune creature would protect you, but it’s blatantly untrue to begin with that sharks are immune. q0v世界播

另外,这使得认为鲨鱼软骨可以治愈癌症,因为鲨鱼对它有免疫力的想法变得更加愚蠢。吃免疫动物不仅没有理由保护你,而且一开始就认为鲨鱼是免疫的,这是完全不真实的。q0v世界播


Hundreds of millions of years ago, when the great dinosaurs walked the Earth, dinosaurs had cancer. q0v世界播

数亿年前,当伟大的恐龙在地球上行走时,恐龙患有癌症。q0v世界播

Unless you subscribe to the ABC sitcom’s model of dinosaurs, I think you’ll agree that dinosaurs probably were not prone to sedentary lifestyles with too much smoking, TV, and fast food. q0v世界播

除非你订阅了ABC情景喜剧的恐龙模型,否则我想你会同意,恐龙可能不会倾向于久坐不动的生活方式,吸烟、看电视和吃快餐太多。q0v世界播


There are some facets of modern living that do increase the risk of cancer—smoking, air pollution, probably some foods (though not cell phones; that one seems to be a myth—and certainly not microwave ovens). But the main reason why cancer is on the rise is simply that although we’re getting better at treating cancer, we’re still much better at treating many other diseases than we are at treating cancer. That is, more people die of cancer now because they survive past the age where their ancestors would have died of malaria, smallpox, or the plague. Cancer, you see, is a disease of old age: the longer you live, the more chances your cells have to make errors. Doctors are excellent at keeping people alive long enough to get cancer; now they just need to catch up in treating cancer as well. (Though a cancer patient today will likely live much longer than the same cancer patient thirty years ago.) q0v世界播

现代生活的某些方面确实会增加患癌症的风险-吸烟、空气污染,可能还有一些食物(尽管不是手机;这似乎是一个神话-当然也不是微波炉)。但癌症上升的主要原因很简单,尽管我们在治疗癌症方面做得越来越好,但我们在治疗许多其他疾病方面仍然比我们在治疗癌症方面做得更好。也就是说,现在更多的人死于癌症,因为他们活过了他们的祖先会死于疟疾、天花或瘟疫的年龄。你看,癌症是一种老年疾病:你活得越久,你的细胞出错的机会就越大。医生很擅长让人们活到足以得癌症;现在他们也只需要在治疗癌症方面迎头赶上就行了。(尽管今天的癌症患者可能会比30年前的同一名癌症患者活得更长。)q0v世界播
