Former President Joe Biden was diagnosed with prostate cancer last week, his office said in a statement on Sunday.

The news came after it was revealed that a “small nodule” was detected during a “routine physical exam,” a spokesperson for the former president told ABC News on May 13.

His prostate cancer diagnosis is “characterized by a Gleason score of 9 (Grade Group 5) with metastasis to the bone,” his office said Sunday. “While this represents a more aggressive form of the disease, the cancer appears to be hormone-sensitive which allows for effective management.”

As Biden and his family review treatment options, former President Barack Obama, President Donald Trump and other political leaders began reaching out to share support for the former leader of the United States.

Obama posted a sincere message on X on Sunday evening, saying, “Michelle and I are thinking of the entire Biden family. Nobody has done more to find breakthrough treatments for cancer in all its forms than Joe, and I am certain he will fight this challenge with his trademark resolve and grace. We pray for a fast and full recovery.”

Trump took to Truth Social the same day, posting, “Melania and I are saddened to hear about Joe Biden’s recent medical diagnosis. We extend our warmest and best wishes to Jill and the family, and we wish Joe a fast and successful recovery.”

Former Vice President Kamala Harris also posted on X on Sunday, saying she and her husband are keeping President Joe Biden and his family in their prayers. “Joe is a fighter — and I know he will face this challenge with the same strength, resilience, and optimism that have always defined his life and leadership,” she wrote. Her husband, Doug Emhoff, the former second gentleman under Biden, separately posted his regards.

Former Republican presidential candidate and current Ohio gubernatorial candidate Vivek Ramaswamy showed optimism and called for unity between parties, posting, “Politics aside, let’s pray for the health of our nation’s former President. His case of metastatic prostate cancer appears to be still in the hormone-sensitive disease stage, which leaves open the possibility of effective treatment.”
