正电子发射计算机断层扫描（PET 扫描）通过向你注射放射性葡萄糖并观察它的去向来发现癌症。

肿瘤会像圣诞树一样亮起来。

健康组织则不会。

诊断你癌症的机器，从机械原理上来说，是一个糖检测器。它所检测的东西，正是癌症正在消耗的东西。

然后，你的主治肿瘤医生会递给你一张传单，推荐在均衡的恢复饮食中加入复杂碳水化合物。

再读一遍。

A PET scan finds cancer by injecting you with radioactive glucose and watching where it goes.

The tumour lights up like a Christmas tree.

The healthy tissue does not.

The machine that diagnoses your cancer is, mechanically, a sugar detector. The thing it is detecting is the thing the cancer is eating.

Your oncologist will then hand you a leaflet recommending complex carbohydrates as part of a balanced recovery diet.

Read that twice.
