我们的身体由无缝连接在一起的各个部分组成,以帮助我们执行日常功能。尽管我们都可以同意,每个身体部位都以自己的方式发挥重要作用,但其中一些(例如心脏和肺部)可能比其他承受更大的重量。
除了我们大多数人都不了解的日常功能以外,某些部分还具有出色的专业能力。我们不需要这些器官在我们的日常生活中能够做这些事情。但是对于他们设计的特定情况,它们甚至可以胜过我们最好的机器。
No.9 我们的免疫系统每天杀死癌细胞
我们大多数人都不太了解癌症的工作原理,即使每10个人中就有大约4个人会在生命中被诊断出患有癌症。简而言之,尽管整个过程比这里所解释的要复杂一些,但是这是当细胞以任何方式异常生长时发生的事情(因此称为“恶性生长”)。
某些类型的癌症会加速细胞的生长,而另一些类型的癌症则会减慢细胞的生长,任何人都可能发生。癌症风险是我们为拥有如此复杂且不断发展的增长机制所付出的代价。
但是,我们没有意识到的是,身体一直在与癌症的生长作斗争,并且作为胜利者出来的次数要比失去的更多。我们的免疫系统不断检查癌细胞并消灭它们,这一过程在我们的日常生活中一直在进行。
在许多情况下,它要求杀死不会自行死亡并可能变成肿瘤的细胞。尽管我们的免疫系统赢得了我们细胞内进行的许多微小战斗,但癌症仍在所有人群中普遍存在,因为不良的生长仅需赢一次就可以发生。
Most of us don’t quite understand how cancer works, even if around 4 out of 10 people will be diagnosed with it at some point in their lives. Although the whole process is a bit more complicated than can be explained here, simply put, it’s what happens when the cells grow abnormally in any way (hence the term “malignant growth”).
Some types of cancer accelerate the growth of the cells, while others slow it down—and it can happen to anyone. Cancer risk is the price we pay for having such a complicated and evolved growth mechanism.
What we don’t realize, though, is that the body is constantly fighting cancerous growths and comes out as the victor many more times than it loses. Our immune systems are constantly checking for cancer cells and destroying them, a process that’s underway every day of our lives.
In many of those cases, it takes a call on killing cells that won’t die on their own and may turn into tumors. Despite our immune systems winning so many of the mini battles going on in our cells, cancer is still prevalent in all human populations because the bad kind of growth only has to win once for cancer to happen.
