It's possible to have the parents post view and still believe chemotherapy is an incredible tool in the right circumstances.
I don't feel they were talking about it in an over-generalizing way, just saying that if you're living unhealthily you're going to continue to be/get unhealthy. Medicine and treatment can help though, as a band aid in these cases. Of course this doesn't preclude someone who's generally healthy from getting sick, unfortunately.
But your comment is also correct, just misdirected in this case I feel :)
