I was diagnosed with breast cancer in January, I've had a lumpectomy ant a course of radiotherapy. I got the all clear in April. Initially all was fine but over the last few months I seem to be picking up all sorts of minor ailments. I've had a cough for months and last weekend, after a coughing fit I coughed up blood, this has only happened the once , my GP is lovely and has done various tests - bloods etc , but nothing is showing abnormal. I had a follow up appointment and mentioned the blood he's sending  me for a CT scan, he said to rule everything out , I was at Dr on Wednesday and the CT scan appointment has come through already for this Sunday, I'm feeling a little worried now .
