I was also diagnosed with Rectal Cancer and have two children of my own. I know exactly how you feel. As others mentioned the scans will give the doctors a lot of information on the next steps and treatment options. I wish you a full recovery and here are some recommendations I have: Stay Strong, a lot of this is mental, if you fill your mind with positive thoughts and try to be grateful for what you have, this goes a long way. During these times its easy to mentally go down the wrong path, be grateful for your two children and more, exercise as much as possible and get sunlight... Speak with a therapist about your feelings, surround yourself with friends, family and kindred spirits. Try to journal as much as you can. Other recommendations I have is get second, third and fourth opinions on treatment options, this will also give you confidence that you are making the right choice on treatment options. I know you will get through this, you will be strong and make a full recovery. Sending you positive vibes.
