Cancer is not just a chick lit/flick plot line. It is very real. One of the most stupid things you could ever wish has it as well, just so you can have a whirlwind romance. My mom has Stage 4 Lung Cancer and her love life is still the same, okay.
It may be a tasteless joke on your part, but I find it alarming that quite a number of young people has actually wanted to get sick. You know what they say, be careful what you wish for because you just might get it.
