I Am Cancer

I am cancer.
I will take your hair and drink your strength.
I will use your body as a battlefield, fighting you to the death.
I will hide behind you as doctors try to kill me, and you will suffer along with me.
I may take your skin as a trophy, rob you of your eyesight, and maybe take an arm or a leg if I feel like it.
I can take everything you have and everything you are.
Except one thing: those who love you.
I can never take them from you.
But I can take you from them.
