Both bone cancer and multiple myeloma are often mistaken for one another because they both involve the bones. Symptoms are even similar with bone pain and easily broken bones. However, they are in fact two different types of cancer. Bone cancer tumors develop inside the actual bone and are usually contained in that bone if found early enough. Multiple myeloma is a blood cancer that forms in white blood cells that are inside the bone marrow. It usually spreads to other bones and is treated as a widespread disease.
