What causes hematologic cancers?

How are hematologic cancers diagnosed?
The diagnosis of hematologic cancer, however, can only be made with certainty by examining cells from the cancer under a microscope. Bone marrow aspiration and biopsy are common ways to obtain these cells for examination in leukemia and myeloma.
What are hematologic cancers?

What are the most common blood cancers in adults?
