Janet Rowley, cancer genetics pioneer, dies at 88

CHICAGO (AP) — Dr. Janet Rowley, a pioneer in cancer genetics research, has died at age 88.

Rowley spent most of her career at the University of Chicago, where she also obtained her medical degree; she died Tuesday of ovarian cancer complications at her home near the university.

Rowley did landmark research with leukemia in the 1970s, linking cancer with genetic abnormalities — work that led to targeted drug treatment for leukemia. She identified a genetic process called translocation, now widely accepted. By 1990, more than 70 translocations had been identified in various cancers, according to her biography on the National Library of Medicine's website.

She is a recipient of the National Medal of Science, the nation's highest scientific honor and the Presidential Medal of Freedom, the nation's highest civilian honor.
