Glioblastoma unmethylated wildtype brain tumor gr4

On 3/24 my dad was rushed to the hospital after having a seizure at work. He was transferred to AdventHealth in Orlando and had brain surgery on 3/26. After the surgery the biopsy came back as Glioblastoma grade 4. This brain cancer is terminal but he is a fighter and going to fight as hard as he can. Right now he is not able to work or drive and doesn't have much movement in his left hand. If anyone can please help them with some unexpected medical bills it would be so much appreciated.

Life update 10/29.. he has been doing good. His speech is off and he doesn't have much use of his left hand. He wears a device on his head 24/7 called optune. This helps confuse the cells from reproducing. He is being told he will have to retire from the city where he has been for 10 years. This is going to be really hard on my parents as he is the one who brings home the money. He is also the one who carries the insurance.  Without insurance his optune device is 21,000 a month. He can keep his insurance but it will take pretty much all of his retirement pay. He has showed shrinking on his last MRI which is good but it is a very aggressive cancer and it can change very quick. His next MRI is in a couple weeks so fingers crossed for another good scan.
