Brain cancer treatment for Dawna

My mom, Dawna Keever, was diagnosed with a brain tumor a month ago. She is the mother of 6 and grandmother of 10 and until shortly before she was diagnosed, a certified nurse's aide. She is 53. April 10th she had neurosurgery to remove as much of the tumor as possible. 
Unfortunately, we found out this week that her cancer is very rare and rapidly regrows. While we hold hope that treatment may give us more time with her, the odds are not in our favor. Please help us be able to make her more comfortable in the limited time we have with her.  Appointments and future treatments are costly. Please help, if you are able. Thank you for your time.
