Former U.S. President Joe Biden is grappling with an advanced stage of prostate cancer that has spread to his bones, causing significant pain and physical limitations. The latest update was shared by Biden's son, Hunter Biden, during a BBC interview on August 8, 2026. This news comes over a year after Biden's office first disclosed his diagnosis with an aggressive prostate cancer that had already spread to his bones. Initially diagnosed in May 2025 due to worsening urinary problems, the disease was found to be particularly aggressive, with a high Gleason score of 9 out of 10, indicating one of the most aggressive cancer types (Grade Group 5). The cancer has now become more debilitating and painful, making it challenging for Biden at the age of 83. The focus of treatment now is on managing symptoms and halting further progression rather than aiming for a cure, as metastatic prostate cancer typically becomes a chronic condition requiring ongoing vigilance. Prostate cancer can be tricky to detect, often causing no noticeable symptoms until it has advanced. Biden's diagnosis came after he noticed increasing urinary problems and his physicians found a suspicious nodule. The disease is most likely to spread to the bones, as was the case with Biden, making early detection crucial. Age is one of the strongest risk factors for prostate cancer that metastasizes to bone.
