Former President Joe Biden has been diagnosed with an aggressive form of prostate cancer that has spread

• Biden's office disclosed his condition on Sunday after a "small nodule" was discovered on his prostate last week while at a hospital in Philadelphia. "While this represents a more aggressive form of the disease, the cancer appears to be hormone-sensitive which allows for effective management," a statement from his office said.

Former President Joe Biden has an aggressive form of prostate cancer that has spread to his bone, according to a statement from his office on Sunday.

The disclosure came after a "small nodule" was discovered on his prostate last week while at a hospital in Philadelphia after experiencing increased urinary symptoms.

"On Friday, he was diagnosed with prostate cancer, characterized by a Gleason score of 9 (Grade Group 5) with metastasis to the bone,” his office said Sunday.

The statement added that, “While this represents a more aggressive form of the disease, the cancer appears to be hormone-sensitive which allows for effective management.”

Biden and his family “are reviewing treatment options with his physicians,” it continued.

Biden, 82, left office as the oldest serving president in American history. He recently began speaking out against President Donald Trump's stance on Ukraine as well as his talk of taking over Greenland, Canada and the Panama Canal.

But the release of the book Original Sin has reignited questions about his Biden's cognitive decline and decision to run for re-election.

In addition, the recent release of audio from Biden's 2023 interview for a special counsel probe on his handling of classified documents raised fresh concerns. 

Biden eventually stepped aside last summer after a disastrous debate performance and endorsed then-Vice President Kamala Harris to succeed him.
