Biopsy of the spine

On April 11th I had an MRI due back/weakness pain and leg pain. On 14th April radiologyst sent through that there were lesions and suspected widespread metestesis although this wasnt picked up until May 7 when they told me. Since then a CT scan showed the same and due to me having breast cancer in 2011 they assume it is coming from the breast, although, that at the moment seems to be clear. However, they said I will need a biopsy in my spine which was a week ago and they are having trouble finding a specialist to analyse it. They have contacted the senior radiologist who isn't  getting back to the consultant so asked me to call again Wednesday if I hadn't heard anything. If they can't do the biopsy because the area they need to take from is a specialist field then they will start me on treatment, even though they dont know what that will be at the moment. I will not have chemo again but has anyone else had this problem, it is now 2 months since they found this
