I was diagnosed 4oc in March 2012, had chemo then surgery then chemo/Avastin and finally Avastin on its own. Just had last one but unfortunately ca markers have started to go up usually around 10 but then 15, 27 and yesterday 37. Luckily my scan was clear so no tumours detected but my doctor says it probably means the cancer is coming back :-(. There is an outside chance it could be something else causing the rise but not holding my breathe. Anyone had experience of this?
