Noncancerous Bone Tumors
Introduction
Noncancerous bone tumors are benign, which means they are not cancer and in general never or rarely spread to other areas of the body. However, they can cause problems because they may weaken bones, interfere with joint movement, or destroy nearby healthy tissue. Benign tumors may be painless, but often they cause bone pain. The pain can be severe. Pain may occur when at rest or at night and tends to progressively worsen. (See also Overview of Bone Tumors .)
