I wish I had cancer
Why would you like to have cancer?
I want to know how it feels to have a disease in a human body
It's good to try to empathize, but cancer is something no one should wish on themselves or others. It's a very serious and dangerous disease that is extremely painful. You should just support cancer patients instead.
I would feel great If got it.
It's not great to have cancer. You should go to hospital and see how cancer patients have to fight it. That'll change your opinion.
