Cancerous diseases may or may not specifically involve blood cells, but cancer treatment can destroy the bodys ability to manufacture new blood cells. Red bone marrow also contributes, along with the liver and spleen, to the destruction of old red blood cells. The new blood cells are released into the sinusoids, large thin-walled vessels that drain into the veins of the bone. Bone marrow is the spongy tissue inside some of the bones in the body, including the hip and thigh bones.
