Help Mom/Brother with Cancer

I am wishing to raise money for my Mother(Marilyn Anfinson). She has been the sole caretaker for my brother, Jeff, for the last 8 years. He was diagnosed with cancer in his left tonsil and the chemo and radiation he had pretty much destroyed his throat. He has severe neck spasms as well and is now on disability because of it. Jeff lost his job at the hospital (he was an ICU/CCU nurse for the same hospital for over 25 years). After his cancer diagnosis, he was put on severe pain meds and became addicted to them. He lost his job because of this addiction to the pain meds. He hasn't worked since.
His cancer is now back in his tongue and voice box. He has had a tracheotomy done to help him breathe easier and is no longer able to eat and is on a feeding tube. The doctors are basically telling him they would have to cut his tongue and voice box out, if he is to stand even a chance for a few more years. He is only 58.
His body is not handling things well, so surgery may not even be an option. The doctors say unless things change, he may only have 6 to 12 months left.
My Mom had been a school teacher for over 30 years and has since retired, but we all know that is not a very large pension to live on and take care of her sick son. 
The money would be used to pay for trips to the hospital (2.5 hrs away), gas, food and hotel room stays while Jeff is hospitalized and being treated, as well as his growing medical bills and his final expenses. His burial will be the responsibility of the family as well.
I do not want my Mom to be the one holding on to that burden. 
She has done a phenomenal job taking care of Jeff, and I would like to help her out with the financial burden so she still can have retirement money to live on.
