Hi I'm 38 and I recently started to have pains in my ribs and chest seemed to come on more when I had a period so I had a few checks and I have been diagnosed with breast cancer grade 2. The  lump was so small they advised they would take it out and be given hormone tablets however the scans showed lesions on my bones so I was advised it had spread and now have stage 4 breast cancer. Where it gets more confusing is now I am being told that the spread can't have come from my breast as a primary and they are doing more tests to see how this has occurred as there isn't another primary cancer in my body. I am so frustrated and confused. I have started hormone ttreatment but now been tested for other issues that may be related to blood rather than bone. Has anyone experienced a wrong disgnosis. I had the Astra Zeneca three weeks prior to all of this and never ever felt pain prior and always healthy and now im a mystery I just don't know what to think
