: The focus has shifted from basic blood smears to the deep genetics of cancer cell biology.

While hematology was established early, emerged much later as a specific branch. In the mid-1950s and early 1960s, a subset of hematologists began experimenting with chemotherapeutic agents to treat malignancies like leukemia and lymphoma.
