Hawk52: No, no there's not. It's fine to exist in a fantasy world where things magically get better, but reality is reality. There are inescapable realities of life and terminal illness is one of those.
It's possible they got a false positive on the tests. But if not, it's called Terminal for a reason. It will eventually kill you, it's just a matter of how long you want to prolong it and how long it takes to claim you. It could be months or it could be years but there's no known cure and even TB seems to have resolved himself to that fact. That doesn't mean not to fight, but to be realistic about the situation. Do what he loves to do and try not to have any regrets for when it comes or IF it comes.
Edit: I should add my aunt died last April from Cancer. They did everything they could to fight it, but it took her when she became too weak. I resolved myself to the fact that she was going to die just like I did for my Grandfather who also died of cancer. If you exist in a world where "miracles" and "hope" can miraculously heal terminal patients then all you're doing is setting yourself up for the bitterness of the truth. She left surrounded by family and friends and I spoke at her funeral myself; leaving with no regrets and with love is far more important then "hope".

tinyE: In 1932 my grandfather was diagnosed with TB which at the time carried a 99% mortality rate.
He was told by his doctors to find a nice sanitarium and get his finances in order to which he replied to them "Fuck You."
He died.
In 1986.
If he didn't have hope I'm not here right now.
I'm sorry about your uncle.
Uncle? Aunt?
Back on topic, I suspect that cancer mortality is also cause by the so called medical treatment.
They hit the patient with this radiation, that drugs, that operation. And all that served to weaken the patient body and immune system.
Really, everybody has cancel cells. When the body fail to keep the cancel cells under control, it becomes cancel sickness. The chances of a weaken body keeping cancel cells under control is even lower.
We have not short of stories of terminal patients giving up to chemo to spend their remaining lives peacefully, have a change of diet and lifestyle, then live much longer than expected or cured completely.
Did your Grandfather go for more chemo / operation after he shunned the doctors?
