Joe Biden’s assistant, Kelly Scully, announced on Monday that the former president of the United States has finished a round of radiation therapy for prostate cancer. The 82-year-old was treated at Philadelphia’s Penn Medicine Radiation Oncology.

During his departure from office, Biden’s post-presidential office had already disclosed that he had been diagnosed with an aggressive type of prostate cancer by medical professionals. It was reported that the disease had already spread to his bones. He complained of urinary problems in May, and following medical assessments, the diagnosis was made. He also had one of the most aggressive forms of prostate cancer, with a Gleason score of 9, which the medical team regarded as dangerous. Prostate cancer is scored from 6 to 10, with scores between 8 and 10 often indicating a more quickly growing and hard to treat kind.

Since leaving the White House in January, Biden has been focussing on his health. He stopped the election effort last year after a bad debate performance against Donald Trump. As worries about his age, strength, and mental clarity grew, he made the choice to leave the public eye. Biden had surgery last month to remove skin cancer spots from his forehead in addition to receiving therapy for prostate cancer. Due to his assistants, he is still in a good mood and responds well to treatment.

It seems likely that the former president would continue receiving follow-up care while being observed by his medical staff. Biden is committed to making a full recovery and continuing to be involved in his post-presidential duties, according to family sources, but doctors have not disclosed any further information on his current treatment plan.
