Joe Biden has been living with an aggressive form of prostate cancer since his diagnosis became public in May 2025. Does Joe Biden have cancer remains a widely searched question, but the answer is confirmed: the former president was diagnosed with prostate cancer that had already spread to his bones. His latest public comments in September 2026 provide a more encouraging update on his treatment while also making clear that his medical condition remains serious.
Biden, now 83, has continued to make selected public appearances and work on personal projects despite his diagnosis. His most recent health update came during Prostate Cancer Awareness Month, when he said radiation treatment he received the previous fall had “worked as intended.” He also thanked the doctors, nurses and other medical professionals who have been involved in his care.
Joe Biden’s Prostate Cancer Diagnosis
Biden’s personal office announced his diagnosis in May 2025, several months after he left the White House.
The former president had been experiencing increasing urinary symptoms when doctors discovered a prostate nodule. Additional medical evaluation resulted in a diagnosis of prostate cancer with a Gleason score of 9, classified as Grade Group 5.
The cancer had already metastasized to his bones.
That detail made Biden’s diagnosis significantly different from prostate cancer detected at an early stage. When prostate cancer remains confined to the prostate, treatment can often be aimed at eliminating the disease. Once it spreads to distant parts of the body, doctors generally focus on controlling the cancer, slowing its progression, managing symptoms and preserving quality of life.
Biden’s office also said the cancer appeared to be hormone-sensitive. That characteristic can allow doctors to use hormone-based treatments to reduce the cancer’s ability to grow.
What Does a Gleason Score of 9 Mean?
The Gleason grading system is used to assess prostate cancer cells based on how abnormal they appear under a microscope.
A Gleason score of 9 is considered a very high-grade result. It indicates that the cancer cells have characteristics associated with aggressive disease.
The score is not, by itself, a prediction of how long a patient will live. Doctors consider numerous factors when evaluating an individual with prostate cancer, including the patient’s age, overall health, extent of cancer spread, response to treatment and other medical findings.
In Biden’s case, the metastatic spread to his bones was particularly significant.
It is also important not to confuse the Gleason score with the cancer stage. The Gleason score describes the appearance and grade of the cancer cells, while staging describes how far the cancer has spread.
Has Biden’s Cancer Spread?
Yes. Biden’s cancer had already spread to his bones when his diagnosis was announced.
The condition was subsequently described publicly as advanced or Stage 4 prostate cancer. In August 2026, Biden’s son Hunter Biden provided additional details about the seriousness of his father’s condition, saying the cancer had metastasized into his bones and further and that his father had experienced significant pain.
Those comments attracted considerable attention because they offered a more difficult picture of Biden’s health than some of the former president’s own brief public statements.
Biden’s most recent message, however, emphasized the positive response to his radiation treatment. The two developments are not necessarily contradictory. A patient can have advanced cancer while also responding favorably to treatment.
What Treatment Has Joe Biden Received?
Biden has received multiple forms of treatment for his prostate cancer.
His representatives confirmed in 2025 that his treatment included hormone therapy and radiation. Hormone treatment is an important tool in managing prostate cancer because many prostate cancer cells depend on male hormones, particularly testosterone, to grow.
Reducing or blocking the effect of those hormones can slow the disease.
Biden also underwent a course of radiation therapy. In October 2025, his spokesperson confirmed that he had completed a round of radiation treatment.
Months later, Biden offered his clearest public assessment of that treatment. In September 2026, he said the radiation treatment from the previous fall had “worked as intended.”
He did not publicly provide detailed medical measurements, imaging results or laboratory findings. Consequently, the precise extent of the treatment response remains private.
Is Joe Biden Cancer-Free?
There is no public announcement that Biden is cancer-free.
His latest comments should not be interpreted as a declaration that his cancer has disappeared. Saying that radiation treatment worked as intended indicates that the treatment achieved the result doctors were seeking, but it does not necessarily mean that metastatic cancer has been eliminated.
This distinction is especially important in cases involving prostate cancer that has spread to the bones.
Advanced prostate cancer can sometimes be controlled for long periods with modern treatments. Patients may experience periods when the disease responds well to therapy, followed by additional treatment if the cancer becomes resistant or begins progressing again.
Biden has not publicly stated that he is in complete remission or that doctors have declared him cured.
What Did Biden Say in His Latest Health Update?
Biden’s latest public health message came in September 2026 as part of Prostate Cancer Awareness Month.
He discussed his personal experience with the disease and urged men to speak with their doctors about prostate cancer screening.
Biden said that by the time doctors found his cancer, it had already reached his bones. He contrasted that experience with early detection, noting that prostate cancer caught at an early stage can have a very high survival rate.
He also expressed gratitude toward the medical professionals who have treated him.
Perhaps the most significant part of the update was Biden’s statement that radiation treatment had worked as intended. He added that he continues to do things that are important to him, including finishing his memoir.
The message provided an optimistic glimpse into his current life without suggesting that his underlying diagnosis has disappeared.
How Is Biden Doing Day to Day?
Biden’s post-presidential schedule has become more limited since his cancer diagnosis, but he has continued to participate in selected public activities.
His family has indicated that the illness has affected his physical condition. Hunter Biden’s August 2026 comments were particularly candid about the pain associated with his father’s advanced disease.
At the same time, Biden has continued speaking publicly about issues that matter to him.
He has also remained involved in the preparation of his memoir, demonstrating that he continues to work on projects outside the political spotlight.
The combination of ongoing treatment and public activity illustrates the complicated reality of living with advanced cancer. A serious diagnosis does not necessarily prevent a patient from maintaining relationships, pursuing projects or appearing at important events.
Biden’s Cancer Diagnosis Has a Personal Connection
Cancer has long been an important part of Biden’s personal story.
His son Beau Biden died from brain cancer in 2015 at the age of 46. The loss had a profound impact on the Biden family and influenced Joe Biden’s later efforts to promote cancer research.
During his presidency, Biden revived the Cancer Moonshot initiative, which sought to accelerate cancer research, improve prevention and detection and reduce the burden of cancer on American families.
His own prostate cancer diagnosis has therefore added a deeply personal dimension to his long-standing interest in the disease.
Biden has used his experience to encourage men to take prostate health seriously and to speak with their doctors about screening.
Why Early Detection Matters
Prostate cancer can behave very differently depending on when it is discovered.
When the disease is localized, treatment options can include surgery, radiation, active surveillance and other approaches depending on the individual case.
Once prostate cancer spreads to distant organs or bones, treatment typically becomes focused on long-term disease management.
That difference helps explain why Biden has repeatedly emphasized early conversations between men and their doctors.
Screening decisions are individualized. Age, family history, race and other risk factors can affect when a person should discuss prostate cancer screening with a medical professional.
There is no single screening schedule appropriate for every man. Physicians may discuss the potential benefits and limitations of tests such as the prostate-specific antigen, or PSA, blood test and determine whether screening is appropriate.
What Is Biden’s Current Cancer Status?
The most accurate description of Biden’s current health is that he has advanced prostate cancer and has undergone treatment for the disease.
His latest public comments indicate that his radiation treatment produced the intended result. That is a positive development, particularly given the seriousness of his diagnosis.
However, the public does not have access to all of Biden’s medical records, scans, blood-test results or treatment plans. Without those details, it would be inappropriate to speculate about whether the disease has progressed, remained stable or entered a particular stage of response.
His family’s comments also suggest that the illness continues to affect him physically.
Therefore, reports describing Biden as completely cured should be treated cautiously unless his doctors or representatives make such an announcement.
Does Joe Biden Have Cancer or Is His Diagnosis a Rumor?
There is no credible basis for describing Biden’s cancer diagnosis as a rumor.
His office officially announced the diagnosis in May 2025, explaining that he had an aggressive prostate cancer that had metastasized to his bones. Biden has subsequently spoken about the illness himself, including in his September 2026 message.
The question of when the cancer developed is separate from whether the diagnosis is genuine.
Prostate cancer can exist for an extended period before it is discovered, and screening does not guarantee that every cancer will be detected at an early stage. A diagnosis being made after a person leaves office does not establish when the cancer first developed.
Biden’s medical history has understandably received extensive public attention because of his former position as president and his age. Nevertheless, conclusions about the exact timing of the disease’s development should be based on medical evidence rather than political speculation.
What Happens Next for Biden?
Biden’s future treatment and medical schedule have not been fully disclosed publicly.
His latest update indicates that he remains focused on his personal life and ongoing projects while continuing to deal with the disease.
His memoir is another major focus. Biden has said that he continues working on the book, giving him a substantial project during his post-presidential years.
Further health updates will likely depend on decisions made by his medical team and how the cancer responds over time.
For now, the most important development is that Biden has reported a favorable response to his radiation treatment while continuing to live with a serious metastatic cancer diagnosis.
Final Takeaway
Joe Biden’s prostate cancer diagnosis is confirmed, and the disease was already advanced when doctors discovered it in 2025. The cancer had spread to his bones, placing him in a category that requires continuing medical treatment and monitoring.
His latest public update in September 2026 offered some encouragement. Biden said the radiation treatment he received the previous fall worked as intended and said he remains active in areas that are personally meaningful to him.
At the same time, there has been no announcement that he is cancer-free. His family’s recent comments indicate that the disease has had a substantial physical impact, while Biden’s own statements show that he remains engaged with his family, public interests and writing projects.
The former president’s experience also highlights the importance of conversations about prostate cancer, particularly because early detection can make a major difference in treatment options and outcomes.
For the latest developments concerning Biden’s health, readers should rely on verified statements from his representatives and medical professionals rather than unconfirmed social media claims.
