Hi- Yes, great response from DeborahSamantha. Please ask the hospital to assign you a social worker, if they have not done so. Here is the website from komen.org. with good advice. https://www.komen.org/support-resources/financi...
So, yes, a social worker from your hospital, your area, can best guide you. there are others at the hospital (see the link).

Do you have a social worker at the hospital where you were treated that can refer you? We have a few places in MA but all paperwork has to be applied by the social worker.
