DONALD Trump said he was “surprised” the public wasn’t told long ago about Joe Biden’s prostate cancer, as he took a swipe at the former president.

Biden, 82, who served as president from 2021 to 2025, confirmed he had the advanced form of the disease in a statement on Sunday.

Trump previously expressed his support for the former president and his family.

He wrote on Truth Social: “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.”

But now Trump has hinted that Biden might have been hiding his diagnosis from the public.

This comes after a leading oncologist claimed that Biden likely had cancer when he took office in 2021.

Dr Zeke Emanuel said: “He had it while he was President.

“He probably had it at the start of his presidency, in 2021.”

Biden announced his cancer diagnosis in an official statement from his personal office on Sunday.

The statement said that he was seen by doctors last week after suffering urinary symptoms, with a prostate nodule then being found.

He was then diagnosed with prostate cancer on Friday, with the cancer cells having spread to the bone.

Biden has previously struggled with his physical health, with some saying he had grappled with numerous health issues during his final year in office.

Biden served as US president from 2021 to 2025, with his term ending on January 20 when Donald Trump took office.

There had been reports in the past Biden was “disoriented and out of it” during cabinet talks and that he had also struggled to recall certain memories, including that of his son Beau’s tragic death in 2015.

Biden was also forced to step down from his campaign for a second term in office, with the Democratic Party nomination being succeeded by his much-younger vice-president Kamala Harris, amid fears over Biden’s cognitive health.
