Hi,
I know exactly how you are feeling. My sister had a brain tumor and I was her carer. And today I help, lecture and care for people suffering with cancer.
Each person is different when it comes to fighting cancer, some give up the fight mentally and lose the fight altogether, while others remain strong throughout the whole experience.
At the end of the day, its extremely important for YOU to remain POSITIVE and encouraging even when its hard to, make sure those who are in contact with him are the same. When he is surrounded by a positive, happy and cheerful atmosphere he will become the same himself.
I have found from experience that those who are negative, sad or disheartened often lose the fight.

So comfort him, entertain him, do what you can to encourage and give him hope-it will pay off. I have a book on how to overcome disease and how the power of the will plays an important and crucial role- I give it to all of my patients and they treasure it and gain PRACTICAL instruction on this subject. If you would like a FREE one, please let me know.
Have you considered using alternative treatments?
All the people I treat use the natural way as they have tried the allopathic way and are now at the point where the doctors have told them there is no hope. The good news is, that most of my patients recover and are cured, it usually takes 9 months or so.
Good luck
Take Care
