I believe that cancer would not increase because now a days their is different ways to diagnose cancer and their is medication to help prevent cancer from spreading through your body, and medicine that would get rid of cancer.However heart disease isn’t really a sickness that can be cure because if your heart is bad you would need a transplant and usually to get one you are put in a waitlist so It may take days,month,even years to get a new heart
I hope that answer your question
