Your body is made of cells, your muscles, your bones, your organs are all thousands and thousands of tiny cells all with a certain job to do to keep your body working.

Cancer is what we call it when those cells are damaged and stop doing their job the way they are supposed to. Instead of doing the drop of keeping your body running, that cell just starts growing and using up the resources that the rest of your body needs. And the damaged cell starts converting other cells to join it in being broken and growing uncontrollably. Soon, the part of your body that has the cancer isn’t doing its job to help you live anymore. Or, it’s dreaming all the resources you need for the rest of the body, making you very weak.

The trick is that different types of cells are going to be different types of cancer. And that we can’t use the same treatments for one type on all of the others.

Part of what makes cancer very hard to fight is that it’s not something outside of your body causing a problem, like a virus or bacteria. Your body doesn’t really realize there’s a problem because your body is the problem.

We’re getting better at coming up with ways of treating certain types of cancer, and we’re always working on improving how we handle it. However, this is a very tricky problem. And it’s more than just one problem, it’s dozens of problems because there’s dozens of types of cancer that need to be researched.
