Trump Says He Doesn't Feel Sorry For Biden's Cancer: 'He's Vicious'

President Donald Trump said on Friday he doesn't feel sorry for Joe Biden's cancer diagnosis, saying "he's vicious."

Addressing press at the White House, Trump said "if you feel sorry for him, don't feel so sorry, because he's vicious." "What he did with his political opponents and all the people that he hurt. I really don't feel sorry for him," he added.

Biden didn't immediately react to Trump's comments. He did address media on Friday, saying "the prognosis is good" and that "we're working on everything." He added that he has started treatment, which involves "taking a pill for the next six weeks, and then another one. And the expectation is we're gonna be able to beat this." "It's not in any organ. My bones are strong, it hasn't penetrated."

Trump initially expressed sympathy for Biden, but has since gone back to attacking him. Earlier this week he shared a social media post that called the former president a "decrepit corpse."

Biden announced earlier this month that he was diagnosed with an "aggressive form" of prostate cancer, which has spread to his bones. He was diagnosed when he reported some urinary symptoms, which led doctors to find a "small nodule" on his prostate. The cancer has been characterized by a Gleason score of 9 and Grade Group 5 with bone metastasis.

"It's the most aggressive type," Dr. Marc Siegel, an internist, clinical professor at NYU Langone Medical Center and prominent medical commentator, told Fox. "That means it has the highest risk of spread— which obviously he has had."

Siegel had anticipated that doctors could seek hormone therapy to treat Biden's cancer. But they could also attempt to radiate the lesion found on the bone or remove the prostate altogether. More than 80% of men over the age of 80 years old have some prostate cancer cells in their body, according to the Doctor.

Further, there are two types of medications used to treat this type of advanced prostate cancer— Lupron, which stops testosterone production, and Casodex, which stops testosterone from binding. Side effects of the medication can leave people feeling "fatigued and listless," according to Siegel.

Biden left office in January as the oldest-serving president in American history, at 82 years old. Throughout his presidency, he faced questions about his age and his health, ultimately leading him to abandon his re-election campaign under pressure from his own party.
