renal cell carcinoma,arachnoid cyst

I had back pain when they did an x-ray they found a large 7cm cyst on my left kidney the local urologist said it was nothing to worry about..however i had a mri and ct...they found a cyst on t-12-L-1 I also had disc bulge at L-4,5 and C-4--5 .The renal cyst was found in April of 07 I was sent to therapy but it anly made my pain worse finally i insisted on a second opinion the urologist at dartmouthhitchcock took on look and said it should be removed the cyst turned out to have a tumor inside that tested positive for renal cell carcinoma..my back pain has become almost unberable and my doctor wants me to try a pain clinic..i feel that i'm getting the same run around on my spine cyst that i had on my kidney ..my last mri showed the spine cyst has grown about i cm in the last year it is now 2.6x1.6x1.6  there is scalloping and enlargmentof the spinal canal also nerve root compromise cannot be excluded.
Would you think my back pain could be caused by this cyst also with the history of cancer do you think it could also contain cancer cells as my kidney cyst showed no signs until it was removed, tested..thank you for your time john
