I have a NET in the rare location of my breast, so I empathize. Much of the world is out of our control but as you probably already know--our attitude is under our control. I learned this in part from philosopher Victor Frankel--and he was in Auschwitz and had lost his family. As a doctor, he turned down the chance to escape because he wanted to stay with his patients. And he survived. I think your toughness of mind will serve you well, but my only advice is to focus on yourself and not on outcome. Outcome is more in G-d's hands...or for a less religious person--based on chance or fate. Wishing you all the best. I'll add that the 8 months since my diagnosis have been challenging but also full of richness, connection, and even fun.
