Here is a closer view of bone metastases. Virtually all bone metastases are from carcinomas. The primary sites of carcinomas that commonly go to bone are: breast, prostate, kidney, thyroid, lung. Renal cell carcinomas tend to be osteolytic (they destroy the bone) whereas prostatic adenocarcinomas tend to be osteoblastic (they initiate new bone formation).

	Vertebral osteoblastic metastases		Chest, osteoblastic metastases
	Chest, osteolytic metastases		Pelvis, osteolytic metastases
