(CNN) — Former President Joe Biden has completed a course of radiation therapy as he battles prostate cancer, a spokesperson for Biden told CNN.

It is unclear what Biden’s next treatment steps might be. The spokesperson did not provide details about future treatment options for the former president, who will turn 83 next month.

Biden’s daughter, Ashley, posted a short video of her father ringing the bell, a tradition for many cancer patients upon completing a round of treatment, at Penn Medicine Radiation Oncology in Philadelphia.

“Rung the Bell!” Ashley Biden wrote in an Instagram story. “Thank you to the incredible doctors, nurses, and staff at Penn Medicine. We are so grateful!”
