Former President Joe Biden is undergoing radiation and hormone therapy as part of a treatment plan for an aggressive form of prostate cancer, a spokesperson said on Friday.
A person close to Biden said the 82-year-old former president “is doing well and responding to treatment.” Another person familiar with the matter said the therapy began “a few weeks ago and it continues.” Biden is reportedly receiving care at a medical facility in Philadelphia.
Biden was diagnosed in May 2025 with “prostate cancer, characterized by a Gleason score of 9 (Grade Group 5) with metastasis to the bone,” according to a statement released by his office at the time. Doctors discovered the cancer after identifying a small nodule in his prostate.
A Gleason score measures how abnormal cancer cells appear under a microscope — the higher the score, the more aggressive the disease. A score of 9 is considered among the most severe categories, placing Biden’s diagnosis in the high-risk range.
Prostate cancer is the second-most common cancer affecting men, according to the Cleveland Clinic, and is most often linked to age. Treatment options include radiation, chemotherapy, surgery, and hormone therapy, depending on severity and stage.
Biden, who served as the 46th president, has previously undergone treatment for skin cancer. Two years ago, while still in office, the White House physician said a basal cell carcinoma was removed from his chest during his annual physical.
In September 2025, Biden also underwent Mohs surgery, a procedure that removes thin layers of cancerous skin until only healthy tissue remains. That surgery was successful, his office said at the time.
Biden has maintained a low public profile since leaving the White House in January, appearing occasionally at political fundraisers and veterans’ events.
