In what ways, at a physics standpoint, is cancer either caused or "cured"?

I have to do a project for IB (group 4 project) and it has to be about physics. Group 4 is the other sciences (physics, chem., and bio.) and I need to present a topic on "what ways cancer is either caused or 'cured' based on physics". I have some stuff on cellphones causing it. You don't really HAVE to research it but just some ideas would be really helpful.
