Oct. 11 (UPI) -- Former President Joe Biden has begun radiation therapy, in addition to hormone therapy, to treat aggressive prostate cancer, a spokesperson has confirmed.
The radiation treatments will continue over five weeks to treat the cancer that Biden, 82, first announced in May.
"As part of a treatment plan for prostate cancer, President Biden is currently undergoing radiation therapy and hormone treatment," a Biden spokesperson told NBC News.
When Biden announced his cancer diagnosis, it already had spread to his bones, which his doctors had been treating with hormone medication.
"The expectation is we're going to be able to beat this," Biden told CNN in May.
