I feel so bad for you! None of us are expecting this. I have a Pet scan on Jan 25th. I already survived colon cancer which was genetic. I actually visited my cancer doctor in November and all my blood results were completely normal and they check everything! I take care of my 5 year old granddaughter and the thought of leaving her or my mom behind is more heartbreaking than I can stand. One bit of hope I can give you is that my pulmonary doctor did say that just because a mass is a certain size, does not mean that all of that is cancer. The cancer may be a much smaller area with other cells around it. Did they tell you anything about the lymph nodes? I will keep you in my thoughts! I am so, SO sorry you are going through this and you're not alone!!
