Bone tumour. Light micrograph of a section through a tumour in bone. This is the result of the spread (metastasis) of cancer from the colon. The tumour is an adenocarcinoma that originates from glandular tissue, and still retains a folded, circular structure (darker purple cells, right and upper left) similar to the structure of a gland. Cancers that start elsewhere in the body and spread to bone (secondary bone cancer) are more common than cancers that arise within bones (primary bone cancer). Treatment for secondary bone cancer may include chemotherapy, radiotherapy or transplantation of bone marrow or stem cells. Magnification unknown.
