Joe Biden shared a new health update on Tuesday, September 8, 2026, saying his radiation treatment for prostate cancer worked as intended after the disease spread to his bones. The former president posted the message during Prostate Cancer Awareness Month, months after Hunter Biden publicly described his father’s condition as “not good.” Joe Biden said doctors discovered the cancer after it had already reached his bones. Biden also said his treatment from last fall was effective and that he remains focused on projects including finishing his memoir. What Did Joe Biden Say About Screening? Joe Biden used the update to urge men to speak with their doctors about prostate cancer screening. He cited more than 330,000 expected diagnoses among American men this year, while noting that early detection brings a five year survival rate close to 100 percent. Biden said men at average risk should begin discussing screening around age 50, with current guidance recommending testing every two to four years. He also urged Black men to test earlier, citing a nearly 70 percent higher risk of developing prostate cancer and a death risk that is two to four times higher. Hunter Biden discussed his father’s diagnosis with BBC Newsnight in August, saying the cancer had metastasized beyond the bones and calling the situation “not good.”
