Can I teach yoga to cancer patients?

If you are teaching yoga to cancer patients, you must have a qualification to be covered for these classes. You should request a doctor's note confirming that the doctors are happy for the student to practice yoga. 

In the event a student shows up to your regular class, and they are a cancer patient, it is up to you if you want to accept them into the class or not. Again, you should request a doctor's note and ensure you feel confident enough to take them on as a student on this once-off occasion. 

Always check directly with your insurance provider.
