Blood cancer comes in many forms, each with unique characteristics, prognoses, and treatment options. Leukemia is a type of blood cancer (along with myeloma and lymphoma) that starts in the stem cells (early blood cells) of the bone marrow, according to Sangmin Lee, MD, hematologist-oncologist at Weill Cornell Medicine and NewYork-Presbyterian Hospital.
Leukemia can be divided into additional subtypes, depending on which blood cells are affected (myeloid or lymphocytic) and how quickly the leukemia is progressing (acute or chronic).
