Question

63-year-old female with back pain. what is the most likely diagnosis? a) osteoblastoma b) chondrosarcoma c) ewing sarcoma d) osteosarcoma e) metastasis f) lymphoma

Explanation:

Metastatic bone disease is the most common cause of back pain in older adults (like this 63-year-old female), as primary cancers frequently spread to the spine. The other options are primary bone tumors that are far less common in this age group: osteoblastoma, Ewing sarcoma, and osteosarcoma typically affect younger patients; chondrosarcoma can occur in older adults but is still less prevalent than metastatic disease; lymphoma involving bone is also less likely to be the first presentation compared to metastasis.

Answer:

E) metastasis
