If you compare the before and after, you can see the tissue around it is bigger and the after X-rays don’t have that hinge you can see in here going through the middle. The mass was on the whole humerus almost but only extended out to the back side of my upper arm. The final diagnosis, was a osteochondroma, like my other mass on my rib and under my sternum. I had a CT scan of my chest to make sure nothing spread into my lungs. I had a MRI of my humerus and whole body skeleton scan. The Skeleton Scan is how Dr. Ward found my last cartilage mass under my sternum. After the MRI and other tests, I went in for a biopsy, which is a surgery, to me. Then after waiting two months for the hospital/doctor to tell me the results. The type of mass removal would be based on the results. Since it came back benign/low-grade, the doctor took off just the extended part of the mass, that was bothering me. If it was malignant, the doctor told me, I would lose the whole arm. Good thing it was not.
