In a 70-year-old patient with back pain and no cardiovascular disease, which diagnosis remains a plausible consideration based on the clinical scenario?

• A. Multiple myeloma
• B. Lymphoma
• C. Leukemia
• D. Prostate cancer

Answer: (A)

Persistent back pain in an older adult should raise concern for a malignancy involving the spine. Multiple myeloma is the one that most cleanly fits this scenario in a 70-year-old: it commonly presents with localized axial bone pain due to lytic lesions in the vertebrae and can occur without other cardiovascular issues. This cancer often manifests in this age group and pain patterns in the back or spine are a classic presenting feature, sometimes accompanied by anemia, elevated calcium, or kidney dysfunction (the CRAB features). While lymphoma or leukemia can involve bone and prostate cancer can metastasize to bone, their presentation is less typically centered on isolated back pain in this age without other context. Thus, multiple myeloma remains the most plausible diagnosis given the scenario.
