I am a breast cancer patient and have been amazed at how many others in my situation have not been offered a CA15-3 bloodtest every three months by their GP to monitor their cancer count when initial treatment has finished. The reading should stay below 30. Mine was between 17-24 for around 6 yrs and in one three month period rose to 40. My doctor noted the rise and I was sent for a CT scan which showed I had mets in my liver. It is a useful tool rarely used and I cannot understand why. Please ask your GP about it - so that further disease can be picked up quickly and treatment started. Max x
