Thanks for your reply. I actually went in for my normal 6 monthly blood test. My tumour marker was slightly elevated CA15-3. I have been sitting at 18 since after the surgery. This time it was 51. Sounded high to me but actually was only one over the normal range of 50. My onc though was on to it straight away and just booked me straight in for full body scans, brain MRI bone density tests and another blood test. So it came up in the bone scan. I was having a few achy joints prior but only after going bush walking or doing major gardening so just put it down to being more active or the tamoxifen as it always went and I never needed any pain killers. So that is how I found out. My onc said a lot of her colleagues don't check the tumour markers as they can be elevated for so many reasons other than cancer but I am glad she did in my case even though the news wasn't good.
