Biden Completes a Round of Radiation Therapy as Part of His Prostate Cancer Treatment

Biden had been receiving treatment at Penn Medicine Radiation Oncology in Philadelphia, said aide Kelly Scully.

In May, Biden’s postpresidential office announced that he had been diagnosed with prostate cancer and that it had spread to his bones. The discovery came after he reported urinary symptoms.

Prostate cancers are graded for aggressiveness using what is known as a Gleason score. The scores range from 6 to 10, with 8, 9 and 10 prostate cancers behaving more aggressively. Biden’s office said his score was 9, suggesting his cancer is among the most aggressive.
