What are the long term effects of radiation therapy on a bone?

Supress functions : Bone marrow has many important roles including production of blood cells responsible for immunity, in other blood products. Radiation can suppress normal bone marrow function. It can scar bone marrow. Bone can lose some of its flexibility / tensile strength, so it may fracture easier. Depending on the dose, radiation field, vascularity, there is an a rare but possible complication of necrosis. ...Read more
