Hello @lah115, that is a tough question. Everyone is different in terms of sharing information, but I feel that family members especially deserve to know about a serious illness. Adding a bit of comic relief with a joke might make others at ease to talk more freely. As a medical person, I was always willing to share medical information with family and friends, and would have hated hearing from them later "Why didn't you tell me?". Some people are just not comfortable with detailed medical information though, so a general discussion or colorectal cancer and basic prognosis and treatment plan is enough. My husband and I have found tremendous support from friends, family, and even acquaintances. Sometimes we will learn a bit of new information to research during a cancer discussion. I suggest gaining more information from your oncologist and then sharing what you know and plan to do with at least your family. You might be surprised at the response from friends who may have dealt with this with their family members or friends. All information you gain can be used to advocate for your own healthcare. You are the one in charge of your care plan and can educate yourself to make the best decisions for you. Are you being treated locally or at a regional cancer center?
