Wow! I just got up and I read this. Cancer sucks, lost my mother & an uncle to cancer. 4yrs ago my brother in law had throat cancer, it was the early stages though we all thought Colin was going to die, he couldn't eat solid foods had to be liquid foods and being a roast mutton man he was terribly pissed off. He went through the lost of weight, hair lost, being sick a lot due to the chemo but at the end he recovered and is now back to his normal self & enjoying his roast dinners.
Then early last year my other brotherinlaw was told by his doc he has colon cancer, he too recovered from it and he was late going to the doctors he probably wouldn't off if it wasn't for him collapsing while at work. They both have to have their check ups just in case the cancer ever returns though they both in good spirits.
There is still hope Feuer Frei! The doctors haven't given up on you so they must know there is still a good chance of you beating this cancer. I hope the very best for you man.
Try to stay positive.
