I really need some advice regarding my Dsis. She had a chest X-ray following a chest infection and was then sent for Ct scan. Scan has shown something up and her recent appointment was told it could be lung cancer. She has to go for pet scan waiting on appointment. I am Ill with worry. Can anyone share any experience of this and offer any advice or help at all. She has also had shoulder pain for a while and tired a lot. I am so scared and worried. She is 49, none smoker but used to smoke long time ago. She has kids who need her and we are a tight nit family so this is so scary and unexpected. Has anyone has anything like this and or not be cancer. I have been looking online and lots of scary things to read. Please help xx
