Son: "Hey mom. Why are we getting Christmas presents in July?" Mom: "Because it's cheaper than chemotherapy"
How could you say something like that about people who are ill?
Because I want cancer to be over in my family.  Fuck cancer.
It sounds like you or someone close to you might be suffering from cancer at this time, and it sounds like the situation feels hopeless to you.  You shouldn't give up, though, or make jokes about how everyone is going to die.  Many treatment options have a high chance of success, and there are ways that they can be made affordable.
