What are some good songs to dance to that relate to cancer or being sick?

So im starting my senior project. And its going to be a whole dance show. All proceeds that i make will be going to St. Simon & Judes cancer research foundation. So i was wondering if anyone knew any good songs to dance to. It doesn't have to be just cancer related. Just something like that in general. For example I'm using the song "It doesn't Hurt" by Katie Thompson. It also doesn't have to be a slow song. So anything helps :) thankyou soo soo sooo much :)
