World Castleman Disease Day is July 23!
What is World Castleman Disease Day?
World Castleman Disease Day is recognized each year on July 23 by the entire CD community — patients, loved ones, physicians and researchers. It marks a time when everyone unites to build greater awareness for Castleman disease, to support patients who are living with this disease, and to remember those we have lost.
Our 2025 Campaign
For World Castleman Disease Day 2025, the CDCN is amplifying the voices of patients from around the world by sharing powerful quotes that reveal their journeys with Castleman disease. Through their stories, they express what the CDCN means to them and offer insight into living with this rare condition.
All funds raised this year will go directly toward life-saving research aimed at finding a cure for Castleman disease.
Join us throughout July as we share these inspiring patient experiences across our social media channels to raise awareness and hope. In honor of World CD Day on July 23 (07.23), we encourage donations of $7.23, $72.30, or $723. Every contribution helps accelerate critical research and brings us closer to a cure.
