Medical Bill for Mothers Brain Tumor

My mother Patricia Boren was diagnosed with a brain tumor a little over 3 years ago. My stepdad has been trying to pay for her medical care and their home on his own but he has started to fall behind on bills. Her tumor has continued to grow and at this point he can no longer take on the financial responsibilities on his own so I am here asking for help to get her the care she needs. We want to make sure he doesn't loose his home in the process, and help him afford these medical bills.
