Pope Leo XIV’s older brother, Louis Prevost, is reported to be receiving treatment for a blood cancer diagnosis. Nigerian outlets report that Prevost is battling cancer following the pontiff’s recent medical updates, while CBS News says Prevost’s wife told the network that he has multiple myeloma.

The reports connect the two health developments by describing Pope Leo XIV’s recovery after lung cancer surgery and a diagnosis revealed through that procedure. While the pontiff’s surgery and recovery are discussed across the coverage, the specific focus of the newer reporting is Prevost’s condition and ongoing treatment. The outlets vary in the level of detail provided—Nigeria-based reports cite a general blood cancer battle, while CBS News identifies multiple myeloma and includes direct attribution from Prevost’s wife.
