My Mother was recently diagnosed with pancreatic cancer

My mom was recently diagnosed. Last week, they attempted to do the whipple procedure. However, were unsuccessful due to the fact that the tumor was on 2 of the arteries. In approx 2 weeks, she will be starting chemo and radiation which will last approx 6 months to hopefully shrink the tumor so it will be operable. Any info would be greatly appreciated.
