Joe Biden is receiving radiation therapy for his prostate cancer, a spokesperson for the former US president said.
He was diagnosed with an "aggressive form" of prostate cancer that had metastasised to his bones in May.
"As part of a treatment plan for prostate cancer, President Biden is currently undergoing radiation therapy and hormone treatment," the spokesperson said.
The spokesperson added the radiation treatment is expected to continue for five weeks and is a new stage in his level of care.
Mr Biden, who turns 83 next month, underwent a procedure known as Mohs surgery to remove cancerous cells from his skin in September.
In May his team said the illness was aggressive but hormone-sensitive, meaning it was likely to respond to treatment.
