Bone metastasis (Cancer spread to bones) Bone metastasis occurs when cancer cells break away from the original tumor and spread to the bones, where they begin to multiply. Prostate, breast, and lung cancers are most likely to spread to the bone. However, other cancers are not excluded. Bone metastases do not begin from the bones but move there from the primary tumor. https://t.me/joinchat/AAAAAEIMp_P_-52SlidzHg
