Question

osteoblastic metastasis in an adult male patient likely originated from a primary carcinoma of the _______.

Explanation:

Osteoblastic (bone-forming) metastases are strongly associated with prostate carcinoma, which is the most common primary cancer causing this type of bone spread in adult males. Breast cancer can cause osteoblastic metastases but is far less common in males, while lung and liver cancers typically cause osteolytic (bone-destroying) metastases.
