我們的身體由無縫連接在一起的各個(gè)部分組成，以幫助我們執(zhí)行日常功能。盡管我們都可以同意，每個(gè)身體部位都以自己的方式發(fā)揮重要作用，但其中一些（例如心臟和肺部）可能比其他承受更大的重量。

除了我們大多數(shù)人都不了解的日常功能以外，某些部分還具有出色的專業(yè)能力。我們不需要這些器官在我們的日常生活中能夠做這些事情。但是對于他們設(shè)計(jì)的特定情況，它們甚至可以勝過我們最好的機(jī)器。

No.9 我們的免疫系統(tǒng)每天殺死癌細(xì)胞

我們大多數(shù)人都不太了解癌癥的工作原理，即使每10個(gè)人中就有大約4個(gè)人會在生命中被診斷出患有癌癥。簡而言之，盡管整個(gè)過程比這里所解釋的要復(fù)雜一些，但是這是當(dāng)細(xì)胞以任何方式異常生長時(shí)發(fā)生的事情（因此稱為“惡性生長”）。

某些類型的癌癥會加速細(xì)胞的生長，而另一些類型的癌癥則會減慢細(xì)胞的生長，任何人都可能發(fā)生。癌癥風(fēng)險(xiǎn)是我們?yōu)閾碛腥绱藦?fù)雜且不斷發(fā)展的增長機(jī)制所付出的代價(jià)。

但是，我們沒有意識到的是，身體一直在與癌癥的生長作斗爭，并且作為勝利者出來的次數(shù)要比失去的更多。我們的免疫系統(tǒng)不斷檢查癌細(xì)胞并消滅它們，這一過程在我們的日常生活中一直在進(jìn)行。

在許多情況下，它要求殺死不會自行死亡并可能變成腫瘤的細(xì)胞。盡管我們的免疫系統(tǒng)贏得了我們細(xì)胞內(nèi)進(jìn)行的許多微小戰(zhàn)斗，但癌癥仍在所有人群中普遍存在，因?yàn)椴涣嫉纳L僅需贏一次就可以發(fā)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.
