Former U.S. President Joe Biden, 82, has been diagnosed with an aggressive form of prostate cancer that has metastasized to the bone. The diagnosis, characterized by a Gleason score of 9 (Grade Group 5), was confirmed following medical testing prompted by increasing urinary symptoms. The news was released in a statement from Biden's personal office on Sunday, May 18, 2025.

Despite the aggressive nature of the cancer, doctors indicated that it appears to be hormone-sensitive, which allows for effective management. Biden and his family are currently reviewing treatment options in consultation with his medical team. He is at his home in Wilmington, Delaware.

The announcement of Biden's diagnosis has garnered widespread support from across the political spectrum. Former President Barack Obama expressed his support on social media, praising Biden's commitment to cancer research and wishing him strength. Former President Donald Trump also extended his best wishes for a speedy recovery.

Vice President Kamala Harris shared a message of support on Instagram, conveying her and her husband Doug Emhoff’s condolences and encouragement. She stated that Biden will face this challenge with the same strength, resilience, and optimism that have always defined his life and leadership and expressed hope for a full and speedy recovery.

Concerns about Biden's age and health were present during his time in office and came into focus after a debate performance against Donald Trump in June 2024. In February 2024, a physical examination revealed “no new concerns” with his health. Biden had announced in July 2024 that he would not seek re-election.

During his tenure as vice president, Biden spearheaded the Cancer Moonshot initiative, a program launched under President Barack Obama in 2016. Upon assuming the presidency, Biden reignited the initiative, pledging to significantly reduce cancer mortality rates in the United States.

Social media users from various backgrounds have expressed their support, setting aside political differences to offer comfort and prayers for Biden's recovery.
