Black patients and Hematology
Black hematologists: sickle cell, anemia, clotting, and blood cancers. Over 90 percent of U.S. sickle cell patients are Black, and specialist centers matter.
Sickle cell disease affects roughly 100,000 Americans, more than 90 percent of whom are Black (CDC). Despite affecting 1 in 365 Black births, sickle cell patients face documented undertreatment of pain in emergency departments and limited access to comprehensive care centers. Fewer than 40 of those centers exist nationally. Hematologists also treat iron-deficiency anemia (twice as common in Black women), inherited clotting disorders, and blood cancers like multiple myeloma, which disproportionately affects Black Americans.
Multiple myeloma is 2 to 3 times more common in Black than white Americans (Landgren, Blood), and Black patients experience longer diagnostic delays.
