President Joe Biden's "aggressive" prostate cancer has led to renewed interest in his health during his presidency

Prof Karol Sikora, the former director of the World Health Organisation Cancer programme, said the late revelation of Biden’s diagnosis could point to a “cover-up by his doctors,” but suggested that it was more likely down to a “rapid-growing cancer.”

Former President Joe Biden struck an optimistic tone when discussing his cancer diagnosis for the first time Friday, saying, “We’re going to be able to beat this.”
