If you live near a medical facility associated with a university they usually have some kind of mandate to provide a certain amount of care for indigent patients. Usually the billed amount will be based on your income. Contact the social service department of the local hospital (university or other) and ask about financial help available. Also if you pay cash because you lack insurance most providers offer a rather substantial discount.
Another option is if you have been told cancer is to see if the American Cancer Society will refer you to a doctor who will treat you for little or no charge.
Thank you, will be at it again tomorrow, will try this also.
