Joe Biden has finished a round of radiation therapy treatment, a spokeswoman for the former president confirmed to CBS News.

The president originally reported a metastasized prostate cancer diagnosis in May, and announced he was receiving radiation therapy earlier in October. Biden's May diagnosis labeled him as having an aggressive, high-risk form of cancer.
