Biology-why is cancer like a bad driver?

It is like a bad driver. Let's pretend I am just learning how to drive, and I get a bad grade well, for Cancer it's the same way. If you don't treat it fast enough it can kill you. Or if you don't catch it in time it can lead to lots of different bad liabilities. 

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
