Breast feeding

Hello everyone! I have just been diagnosed with cervical cancer - bummer hay! We are currently in the process of finding out to what degree, I have just had a MRI to get an accurate diagnosis and I am waiting for the results. I’m currently breastfeeding my 5 month old baby (I had to stop for 48 hrs following my radium contrast injection) we both found this hard! I can’t help but feel so guilty about my baby feeding off of my unhealthy body but on the other hand I don’t want to stop if I don’t have to or even until I have to! I find it comforting as does my little one! I’m finding the thought of having to stop feeding my baby so very upsetting, I don’t want to think feeding my baby and having cervical cancer and all the stresses it brings with it is harming my baby it just physically but emotionally too! I’m so confused and don’t know what to do! Can anyone offer any advice please? Xx
