With cancer there is no guarantee. It can return at any time and that is why a patient needs to be constantly vigilant for signs that it has returned. There are many, many programs and services for people who cannot afford medical treatment. If you had cancer previouslyI am surprised that you are not aware of the various program available. Anyway, no one is turned away from medical treatment (you will probably not get a choice however who will treat you), you just need to locate the places that provide the free or low cost services. The American Cancer Society can help you do this if you call them:

There are also certain hospitals that were built with federal funding and in return provide a program called Hill-Burton that essentially covers the cost of anyone unable to pay.
