What causes bone pain from cancer?
• A: When cancer invades the bone it can cause the bone to deteriorate or build up too quickly. Although the mechanism is not fully understood, it is theorized that bone pain occurs due to stretching of the tissue around the bone, which can have an inflammatory effect. It also may result from pressure on nerve roots or muscle spasms. This may lead to a number of problems, including bone pain, swelling and the weakening of bones.
