I, as a Christian, had always heard too, that God will never give us more than we can handle.
But then I heard someone say, sometimes God does give us more than we can handle, but nothing He can't handle. God is bigger than Cancer. God can heal us if He chooses to do so. There have been pan cancer patients who have survived past 5 years. I know we have to be realistic. I know we can't tell God what to do; He is sovereign. But we can be assured, as a believer, that He understands our pain and suffering and that He is there right beside us in our journey. And we can be assured He does hear our prayers and that He loves us.
