Trump on Biden's cancer diagnosis: We need to investigate why we didn't know much sooner

US President Donald Trump spoke openly today about former President Joe Biden's recent prostate cancer diagnosis, expressing regret while also suggesting that the situation should be investigated.

Biden's team announced the diagnosis on Sunday afternoon, saying the former president "was seen for a new finding of a prostate nodule after experiencing increasing urinary symptoms."

"On Friday, he was diagnosed with prostate cancer, characterized by a Gleason score of 9 (Grade Group 5) with bone metastasis," the statement added.

"While this represents a more aggressive form of the disease, the cancer appears to be hormone-sensitive, which allows for effective management," Biden's team concluded.

"The president and his family are reviewing treatment options with his doctors," it was said, among other things, the Telegraph reports.

Speaking to reporters Monday afternoon, Trump called the news "very sad, actually."

"I'm surprised, you know, the opinion wasn't announced a long time ago because to get to phase nine, that's a long time," Trump said.

"I just had my physical. We had the doctors at the White House and at Walter Reed, which is a fantastic hospital. I had a very thorough physical, including cognitive tests," he added.

Trump also referred to Biden's cognitive decline during his presidency, stating that "anyone running for president should take a cognitive test."

"They say it's unconstitutional. But I would say that in that particular case, administering a cognitive test wouldn't be so bad," the Republican said.

Trump also claimed that the public was "not informed" about Biden's medical situation, and suggested that the situation should be investigated.

"I think someone would have to talk to their doctor whether it's the same doctor, or even if it's two different doctors. Why wasn't the cognitive ability discussed, why wasn't that discussed? And I think the doctor said it's fine. And it turns out it's not. It's very dangerous," Trump said.

The president concluded by saying that the cancer diagnosis is "a very, very sad situation and I feel very sorry about it."

"I think people should try to find out what happened, because I'll tell you. I don't know if it had anything to do with the hospital," Trump added.

"Walter Reed is really good. It has some of the best doctors I've ever seen. Someone is not telling the facts," he concluded. "It's a big problem," the US president added. /Telegraph/
