What is the risk associated with osteoblastic lesions?

• A. No fracture risk
• B. Mild fracture risk
• C. Moderate fracture risk
• D. High fracture risk

Answer: (C)

Osteoblastic lesions create abnormal bone formation, so the bone becomes denser on imaging but the new bone is poorly organized and mechanically weaker than normal bone. That means fractures can occur even though the bone looks sclerotic. This raises fracture risk above normal, but it’s typically not as high as with osteolytic lesions, which destroy bone mass more aggressively. So the fracture risk is best described as moderate, especially considering factors like extent and location of metastases and the influence of bone-targeted therapies.
