Joe Biden’s Cancer Diagnosis, What We Know About His Treatment and Prognosis
Quick Answer
Former President Joe Biden was diagnosed with stage 4 prostate cancer in May 2025, after a routine physical prompted by urinary symptoms revealed an aggressive form of the disease that had already metastasized to his bones. The diagnosis carries a Gleason score of 9 (Grade Group 5), indicating a highly aggressive cancer that is considered incurable, though treatable.
Biden continues to undergo treatment — including radiation therapy and hormone treatment as of late 2025 — and is monitored with medical testing every three months, with his family reporting the cancer remains manageable as of mid-2026.Key Facts

The Diagnosis That Reshaped a Public Figure's Final Chapter
When Joe Biden left the White House in January 2025, the public narrative around the former president centered on his age, his legacy, and the turbulence of his final term. Few anticipated that within months, the conversation would shift to something far more personal and urgent.
On May 19, 2025, Biden's office announced that the former president had been diagnosed with prostate cancer. The diagnosis came after a routine physical on May 16, 2025, which was prompted by urinary symptoms that Biden had been experiencing.What started as a standard checkup quickly escalated into a life-altering revelation: Biden had aggressive prostate cancer, and it had already spread to his bones. The timing was notable.Biden had spent decades in public life, and his health had been a recurring subject of discussion throughout his presidency. But this diagnosis was different.This was not a question of stamina or cognitive fitness for office. This was a medical reality that would define the remainder of his life.The announcement came from his office, and the details were specific: a Gleason score of 9, Grade Group 5, with metastasis to the bone. For those familiar with prostate cancer staging, those numbers carried significant weight.A Gleason score of 9 is among the highest on the scale, indicating a cancer that is not merely present but aggressively proliferating. When combined with bone metastasis, the diagnosis moved from serious to grave.The Biden family has a painful history with cancer. Beau Biden, Joe's eldest son, died from brain cancer in 2015 at the age of 46.That loss shaped much of Biden's public advocacy, including his leadership of the Cancer Moonshot initiative during his presidency. Now, a decade later, cancer had come for Biden himself.Understanding the Gleason Score and What It Means
The Numbers Behind the Diagnosis
The Gleason score is the standard grading system for prostate cancer, and it plays a critical role in determining prognosis and treatment approach. The score ranges from 6 to 10, with higher scores indicating more aggressive cancer cells that are more likely to grow and spread rapidly.
A Gleason score of 9 is particularly concerning. It means that when pathologists examined Biden's biopsy samples, they found that the cancer cells bore little resemblance to normal prostate tissue.These cells were highly abnormal, dividing rapidly, and behaving in ways that suggested they would not stay contained within the prostate gland. For context, a Gleason score of 6 is considered low-grade, often slow-growing, and frequently managed with active surveillance rather than aggressive treatment.A score of 7 is intermediate. Scores of 8, 9, and 10 are high-grade and demand immediate, aggressive intervention.Biden's score of 9, combined with the finding that cancer had already spread to his bones, placed him firmly in the category of advanced metastatic prostate cancer. This is a condition for which there is no cure, only management.What Stage 4 Prostate Cancer Actually Means
Prostate cancer staging describes how far the cancer has spread. Stage 4 is the most advanced category, and it is further divided based on the extent of metastasis.
In Biden's case, the cancer had spread to his bones, which is one of the most common sites for prostate cancer metastasis, along with the lymph nodes. Bone metastasis is significant for several reasons.It can cause pain, weaken bones, and lead to fractures. It also changes the treatment calculus dramatically.Localized treatments like surgery or radiation to the prostate alone are no longer sufficient. The cancer is no longer a single tumor but a systemic disease that has traveled through the bloodstream or lymphatic system.The primary goal of treatment in this scenario shifts from cure to control. As the Michigan Medicine article on Biden's diagnosis notes, "In general, the primary goal of treatment is to slow progression." This is a fundamental shift in how patients, families, and doctors approach the disease.Treatment Approach and the Three-Month Monitoring Cycle
The Current Treatment Regimen
In October 2025, approximately five months after the initial diagnosis, a spokesperson for Biden provided an update on his treatment. He was undergoing radiation therapy and hormone treatment.
This combination is standard for advanced prostate cancer with bone metastasis. Hormone therapy, often called androgen deprivation therapy (ADT), works by reducing the levels of male hormones, particularly testosterone, that prostate cancer cells need to grow.This is not a cure, but it can slow the cancer's progression, sometimes significantly. Radiation therapy is often used to target specific areas of metastasis, particularly in the bones, to relieve pain and prevent complications.The fact that Biden was responding well to treatment, as sources told PEOPLE in October 2025, is a positive sign. Hormone therapy can be effective for months or even years before the cancer develops resistance.The goal is to extend that period of control as long as possible.Why Three-Month Testing Matters
Jill Biden has shared that her husband undergoes medical testing every three months. This monitoring schedule is not arbitrary.
For patients with stage 4 prostate cancer, regular testing is essential to track the disease's progression and adjust treatment accordingly. These tests typically include blood work to measure prostate-specific antigen (PSA) levels, which serve as a marker for cancer activity.Imaging scans may also be used to assess whether the cancer has spread further or whether existing metastases have grown. The three-month interval reflects a balance between catching changes early and not subjecting the patient to excessive testing that could diminish quality of life.The three-month cycle also provides a rhythm for the family. Each round of tests brings a moment of assessment, a chance to recalibrate expectations, and a reminder of the uncertainty that accompanies a stage 4 diagnosis.The Family's Public Statements and What They Reveal
Jill Biden's Updates
Dr. Jill Biden has been the primary voice providing updates on her husband's condition, often framing the situation with both realism and hope.
Her statements emphasize that Biden is under close medical supervision and continues to fight the disease with the support of his family. The language she uses matters.When she says the cancer "remains manageable," she is not claiming that the cancer is gone or that Biden is cured. She is acknowledging the reality of stage 4 disease while reassuring the public that the current treatment is holding the line.This is the language of someone who understands the difference between optimism and denial.Hunter Biden's August 2026 Update
On August 7, 2026, Hunter Biden gave an interview to BBC's Newsnight that offered a more somber perspective. He confirmed that his father's cancer had spread and described the experience of watching his father navigate the disease as "really sad to watch."
Hunter's comments reflect a shift in tone from earlier updates.
In October 2025, the messaging was that Biden was "doing well and responding to treatment." By August 2026, the message had become more measured, acknowledging the difficulty of the journey even while stopping short of declaring a crisis. "Cancer is really hard," Hunter said."It's really sad to watch." These words carry the weight of someone who has been through this before. Hunter lost his brother Beau to brain cancer in 2015.He knows what cancer does to a family. He knows the toll it takes on the patient and on everyone who loves them.The timing of Hunter's interview is also notable. It came approximately 15 months after the initial diagnosis.For stage 4 prostate cancer patients, the disease trajectory can vary widely. Some patients maintain good quality of life for years.Others experience more rapid decline. The fact that Hunter chose to speak publicly about the difficulty suggests that the family is navigating a challenging phase.What This Diagnosis Means for Older Men With Prostate Cancer
A Common Disease With Serious Implications
Prostate cancer is the most common cancer among men in the United States, affecting one in eight men. It is also a leading cause of cancer-related death among men.
These statistics underscore the breadth of the disease's impact. For older men, prostate cancer presents particular challenges.Age can complicate treatment decisions, as older patients may have other health conditions that affect their ability to tolerate certain therapies. The balance between aggressive treatment and quality of life becomes more delicate.Biden's case is instructive in this regard. At 83 years old at the time of diagnosis, he represents a significant demographic of prostate cancer patients.His treatment plan — hormone therapy and radiation — reflects a pragmatic approach that prioritizes disease control while maintaining quality of life. This is not a case of pursuing every possible intervention regardless of cost.It is a measured response to an incurable condition.The Public Nature of Biden's Journey
What makes Biden's case unusual is not the medical details but the public nature of his journey. Most men facing stage 4 prostate cancer do so in relative privacy, supported by family and close friends.
Biden's diagnosis and treatment have been matters of public record, discussed in news conferences, interviews, and social media. This visibility carries both benefits and burdens.On one hand, it raises awareness about prostate cancer and the realities of advanced disease. The fact that a former president is undergoing treatment for stage 4 prostate cancer normalizes conversations about a disease that many men are reluctant to discuss.On the other hand, the public scrutiny adds pressure to a difficult situation. Every update is parsed for meaning.Every statement is analyzed for hints about prognosis. The family must navigate their private grief and worry while managing public expectations.The Road Ahead Managing Expectations and Quality of Life
What the Coming Months May Bring
Based on the available information, Biden's cancer is being managed but not cured. The three-month testing cycle will continue, providing regular assessments of whether the current treatment remains effective.
The trajectory of stage 4 prostate cancer is highly variable. Some patients respond to hormone therapy for extended periods, maintaining reasonable quality of life.Others develop resistance more quickly, requiring additional treatments such as chemotherapy, immunotherapy, or newer targeted therapies. The fact that Biden's cancer has spread further, as Hunter noted in August 2026, suggests that the disease is progressing despite treatment.This is not unexpected for stage 4 disease, but it does signal that the current approach may need adjustment in the coming months.The Importance of Family Support
Throughout this journey, the Biden family has remained close. Jill Biden has been a constant presence, providing updates and support.
Hunter Biden, despite his own complicated public history, has spoken openly about his love for his father and the difficulty of watching him battle cancer. The family's experience with Beau's death from brain cancer in 2015 has shaped their approach to Joe's diagnosis.They know that cancer is unpredictable. They know that statistics only tell part of the story.They know that the most important thing is to be present, to be supportive, and to make the most of the time they have. This is not a story with a clean narrative arc.There is no recovery narrative to cling to, no miracle cure on the horizon. What exists is a family facing an incurable disease with honesty, dignity, and mutual support.That, in itself, is worth acknowledging.Frequently Asked Questions
