Can anyone advise me as to whether treatments given for cancer and cause B12 deficiency? I had breastfeeding cancer about 6 years ago and had chemotherapy and radiology.
Have been feeling really unwell for about a year now and all the usual blood tests have come back negative for anything.

Sorry to hear that. Yes some treatments can interfere with B12/folate eg methotrexate. Did you get copies of your results. Post them along with your symptoms for more help here.
Am hoping this website will help with some good information for you about breast cancer....the lady who started it was herself a sufferer...
I was diagnosed with PA 5 months after completing chemo for breast cancer (taxotere & cytoxan). Have never found anything to indicate that it was anything other than a coincidence, but it does make me wonder.
