Louis Prevost faces multiple myeloma relapse

Louis Prevost, the 74-year-old elder brother of Pope Leo XIV, is experiencing a relapse of multiple myeloma. After being in remission since 2017, his condition resurfaced three months ago. He is currently receiving treatment at a hospital in Florida, United States, and is participating in a new clinical trial to manage the progression of the cancer.

His wife, Deborah Prevost, confirmed the diagnosis, noting that the family is navigating a difficult period. This health crisis coincides with medical concerns regarding Pope Leo XIV, who recently underwent surgery for pulmonary adenocarcinoma and is recovering in Rome. While both individuals are facing cancer-related challenges, their diagnoses and required treatments are distinct.
