Former President Joe Biden on Monday completed a round of radiation therapy treatment for the aggressive form of prostate cancer he was diagnosed with after leaving office, a spokesperson said. Biden had been receiving treatment at Penn Medicine Radiation Oncology in Philadelphia, said aide Kelly Scully.

The 82-year-old Democrat left office in January, six months after he dropped his bid for re-election following a disastrous debate against Republican Donald Trump amid concerns about Biden`s age, health and mental fitness. Trump defeated Democrat Kamala Harris, who was Biden`s vice president.
