Former US President Joe Biden, 82, has been diagnosed with an aggressive form of prostate cancer, with the cancer metastasized to the bone.
The cancer is characterized by a Gleason score of 9, indicating a very aggressive form of the disease, but may still respond to hormone therapy.
Biden's cancer diagnosis comes amidst controversy over his mental faculties and age, with Democrats discussing his role as the 2024 presidential nominee.
Having lost his son Beau to brain cancer, Biden has a history of advocating for cancer research funding, including working on a 'cancer moonshot' initiative during his presidency.
