I hope that he does well.
In reality he is going to be exceptionally lucky to 'beat' pancreatic cancer.
Dh is beating the odds, but it is still killing him, just at a slower rate than it was at the point of diagnosis.
IF PS is fortunate he will have a cancer that responds well to treatment. I hope that he does. Having seen what dh has gone through, he will be very, very fortunate if he manages to carry on filming through the treatment.
