Hyperbaric oxigen therapy

Hello. My name is Eduard Storch. I'm a service-technician, employed by a multinational corporation here in Hungary. Until last year, we were living a happy and quiet life, my wife, my 4year old son and me. Then in May, the doctors diagnosed cancer in my left cheek (dont know the correct name for the disease). Since then i'm going from treatment to treatment, but things are going really slow and doesn't really getting any better. After three chemo-therapies, and a radiotherapy, which ended about two weeks ago, i've lost a lot of weight, and since the cancer attacked my mouth, i cant open my mouth at all lately. It's definitely getting worse. My doctor suggested a hyperbaric oxigen therapy, which might repair some of the damage caused by the cancer, but the treatment isn't cheap. This is where i'm asking anyone who is willing to donate to my cause, not even for me, but my son. So he can grow up having a full family, and not without a father. I'm usually a person who stands on his own legs, and don't like to ask for anything from anyone, but in this situation, i don't have any other choice unfortunately. The treatment costs around 1000USD for a 10 day session. But in my case i doubt that only one session would be enough. Thank anyone in advance who can and would help us.
