Former U.S. President Joe Biden, aged 82, has been diagnosed with an aggressive form of prostate cancer that has metastasized to his bones, his personal office announced on May 18, 2025. The diagnosis, revealed after Biden experienced urinary symptoms, has sparked widespread support from political figures and renewed discussions about cancer care. This blog post explores the details of Biden’s diagnosis, the medical implications, public reactions, and the broader context of prostate cancer, crafted to align with Google’s E-A-T guidelines for authoritative, SEO-optimized content.
Joe Biden’s Prostate Cancer Diagnosis: What We Know
On May 16, 2025, Joe Biden was diagnosed with prostate cancer following a medical evaluation prompted by increasing urinary symptoms. Doctors discovered a “small nodule” on his prostate during a routine physical, which led to further testing. The diagnosis confirmed a Gleason score of 9 (Grade Group 5), indicating a high-grade, aggressive cancer that has spread to his bones—a condition known as metastasis.
According to Biden’s office, the cancer is hormone-sensitive, meaning it can be managed effectively with treatments like testosterone-blocking therapies. Biden and his family are currently reviewing treatment options with his physicians, focusing on controlling the disease and maintaining quality of life.
Understanding Prostate Cancer: Aggressiveness and Metastasis
Prostate cancer is the most common cancer among men in the U.S., affecting 1 in 8 men, and the second-leading cause of cancer death after lung cancer, per the American Cancer Society. Biden’s diagnosis, with a Gleason score of 9, places it in the highest-risk category (Grade Group 5), meaning the cancer cells are highly abnormal and likely to spread rapidly.
- Metastasis to Bone: Once prostate cancer spreads to the bones, it is classified as Stage 4 and considered incurable. However, experts like Dr. Judd Moul from Duke University note that men with this condition can live 5 to 10 years or more with proper treatment.
- Hormone-Sensitive Nature: Biden’s cancer responds to hormone therapies that block testosterone, which fuels prostate cancer growth. Treatments like Lupron, combined with newer hormonal therapies or chemotherapy, can slow progression and manage symptoms.
- Symptoms and Detection: Biden’s urinary issues—such as frequent urination or weak flow—led to the discovery of the nodule. These symptoms, along with bone pain or stiffness, are common in advanced cases, per Johns Hopkins Medicine.
Despite its severity, Biden’s case highlights advancements in treatment. Dr. Tanya Dorff from City of Hope Comprehensive Cancer Center emphasized that even advanced prostate cancer patients can live many years with a good quality of life, thanks to modern therapies.
Public Reactions and Political Support
The announcement of Biden’s diagnosis prompted an outpouring of support across the political spectrum, briefly bridging divides in a polarized landscape.
- President Donald Trump: Trump expressed sympathy on Truth Social, stating, “Melania and I are saddened to hear about Joe Biden’s recent medical diagnosis. We extend our warmest and best wishes to Jill and the family, and we wish Joe a fast and successful recovery.”
- Former Vice President Kamala Harris: Harris, who succeeded Biden as the Democratic nominee in 2024, wrote on X, “Joe is a fighter—and I know he will face this challenge with the same strength, resilience, and optimism that have always defined his life and leadership.”
- Former President Barack Obama: Obama highlighted Biden’s contributions to cancer research, saying, “Nobody has done more to find breakthrough treatments for cancer in all its forms than Joe, and I am certain he will fight this challenge with his trademark resolve and grace.”
- International Leaders: UK Prime Minister Keir Starmer wished Biden a “swift and successful treatment,” reflecting global concern for the former president.
Even critics like Rep. Marjorie Taylor Greene offered prayers, citing her father’s death from cancer in 2021. The bipartisan support underscores Biden’s personal impact, despite his controversial exit from the 2024 presidential race amid health and age concerns.
Biden’s Legacy in Cancer Research: The Cancer Moonshot
Cancer has been a deeply personal issue for Biden. His son, Beau, died of brain cancer in 2015, inspiring Biden to lead the Cancer Moonshot initiative as vice president under Obama. Relaunched during his presidency in 2022, the program aimed to halve cancer death rates over 25 years. It funded research, expanded no-cost screenings, and resulted in nearly 8 million people being screened for various cancers, including prostate cancer, per Biden administration records.
Ironically, Biden’s diagnosis comes after years of advocating for better cancer care. His February 2024 physical declared him “fit for duty,” with no mention of prostate issues, highlighting how rapidly the disease can emerge. Some experts, like Dr. Céline Gounder, noted that routine prostate cancer screening in men over 75 is controversial due to slow-growing cases, but Biden’s symptoms justified the evaluation.
Critical Analysis: Age, Health, and Political Implications
Biden’s diagnosis raises questions about health transparency and the pressures of aging leadership. At 82, Biden was the oldest U.S. president in history when he left office in January 2025. His decision to drop out of the 2024 race, after a faltering debate performance against Trump, was driven by concerns over his age and mental acuity—issues that dominated his presidency. Some Democrats, like Senator Chris Murphy, later admitted it was a mistake to advance Biden as the 2024 nominee, given public sentiment about his age.
The lack of earlier detection in Biden’s case is notable. Routine prostate-specific antigen (PSA) tests are not typically recommended for men over 70, as overtreatment can outweigh benefits for slow-growing cancers. However, Biden’s functional activity and new symptoms warranted testing, underscoring the need for individualized medical decisions.
Critically, while Biden’s office attributes the diagnosis to recent symptoms, the absence of prior prostate concerns in his medical reports raises questions about oversight during his presidency. This could fuel debates about the adequacy of health screenings for aging leaders, especially given Biden’s history of health issues like sleep apnea and a 2023 cancerous skin lesion removal.
