Hi,
Other than Medicaid I don't know of direct financial help. Perhaps a foundation like Lance Armstrong Foundation can help. For people traveling to other places, there are other forms of help that I came across in an earlier message on this forum.
Free flights for cancer patients are available through
http://www.angelflightcentral.org/ or
http://www.corpangelnetwork.org/ I heard there is also free lodging through Hope Lodge
http://www.cancer.org/docroot/SHR/content/SHR_2.1_x_Hope_Lod I have no direct knowledge of this - just passing on the info I found on this board.
Take care,
Priya.
