Hi Vick, First I'm sorry your having to look for things that deal with cancer, that sucks in itself. But since you are, there are lots of places to look. first, call the American Cancer Society and explain what your situation is. They have programs to provide partial assistance. Then there are other programs, grants, foundations, local charities, etc. Number for ACS is (800 - 227 - 2345) click on the resources tab at the top of the page, there are some places in your zip code that will come up in that search.
Others on the site will provide you with links to some other places that they know about. Be patient and check back on this question often, there are a lot of helpful people here that will come through.
Wish you the best!
