Saying someone lost the fight implies that there was something else they could have done to win. Cancer is what happens when your body attacks itself. It’s not someone else attacking you. When someone passes away from cancer, their life was stolen. They didn’t lose it. If you’re walking down the street and someone steals your bag, you don’t tell people you lost your purse, you tell people it was stolen. Cancer steals lives. Cancer doesn’t play fair. There are no rules in the fight, no playbook. When someone dies of cancer, they’re a victim, not a loser as the phase “lost the battle” implies.
