Could Multiple Myeloma Be Due To Long Term Usage Of Actonel?

I had been on Actonel for almost 10 years for osteopina and told I was doing well. Four years ago, my doctor took me off Actonel. Two years ago I was told I have severe osteoporosis in my spine. And one year ago, I was found to have spinal spondylosis. In an unrelated test, bloodwork showed protein in my blood and I was diagnosed with multiple myeloma. Eyebrows have been raised and it is now being hinted that I should not have remained on Actonel for so many years. Do you see a correlation between my recent health issues and the fact that I was on the medication for so many years? Prior to two years ago, I considered myself very healthy!
