Former President Joe Biden, who was diagnosed with an aggressive form of prostate cancer in May, completed a course of radiation treatment Monday, his office said.

Axar.az, citing NBC, reports that Biden underwent several weeks of treatment, according to his office.

It was not immediately clear whether Biden, 82, will require additional treatment or measures for his care.

Separately, Biden last month underwent a skin cancer treatment known as Mohs surgery, which involves cutting away layers of skin to address a malignancy. He was seen in public at the time wearing a bandage on his forehead.

Biden announced in May that he had been diagnosed with an aggressive form of prostate cancer that had metastasized to his bones.
