Can Body Pain Be Caused By Anxiety

I recently had an abnormal mamogram and am in the process of being scheduled for a surgical biopsy. The nodule found is very small (4.6mm) and i've been told by the surgeon that even if it were maligant, it would very likely be early stage. Needless to say, I am terrified, of both the procedure and the results. I've had pains here and there over my body in the past and never thought too much of it. However, since finding out about the possibility of having breast cancer, I have pains all over my body in my bones and muscles. The pains come and go. I am convinced I have bone cancer. I'm even starting to think perhaps I have lung cancer that spread to the bones or breast cancer that has spread to the bones. I have suffered from hypochondriasis since I was 12 years old. This time I really believe I am dying from end stage cancer. My question is can the anxiety and stress I am experiencing be causing the pain in my bones and elsewhere in my body? I am 47 years old, don't smoke, do drink alcohol, and have had a recent physical exam with normal blood results. Please help!
