All of this has happened to me within the last week! The Dr sent me for blood tests and a chest xray - as a matter of urgency (according to my Dr) i have been referred to a specialist. The xray revealed a 'shadow' on my left lung. I know that a simple xray is not 100% diagnostic but i cant stop thinking about outcomes, from it not being cancer to having weeks to live! I cant begin to deal with this until i know what is what. It's this damn waiting!!!! Even a diagnosis of cancer would break this waiting and wondering - I feel i am in some type of limbo. It's the uncertainty Do these shadows often turn out to be cancer? Ive had a cough for months, get night sweats and i feel so old at 40 - tired and fatgued. Ive smoked for ten years, stupidly x
