In brief: Sometimes

Sometimes but not always.
Leukemia, a form of blood and bone marrow cancer, is frequently detectable in the blood; however, especially if early in the course of the disease, leukemic cells may be confined to the bone marrow and not cross into the blood in sufficient numbers to be detected by a cbc. Ultimately, the complete diagnosis and prognosis of leukemia relies on bone marrow examination.
