I already knew this had something to do with the immune system. You need to have a strong immune system to fight it off. You need a healthy body to fight it off. That is why they advised people who drink and smoke to stop because it will only make it worst. Women have stronger genes, that is just that. That is why men have a five times chance of getting cancer. Im not saying more women will survive, Im just saying that a healthy immune system is needed to fight this.
