WNBA superstar Breanna Stewart is using her platform to raise awareness for a marrow donor program following the loss of her father-in-law, Josep Xargay, to cancer nearly a year ago. The impact of this personal tragedy has motivated Stewart to advocate for those battling the disease and to encourage others to consider becoming marrow donors. Her efforts aim to highlight the importance of finding matches for patients in need of transplants, as well as to honor the memory of her father-in-law. Through her advocacy, Stewart hopes to inspire others to take action and support the fight against cancer.
