Former US president Joe Biden has been diagnosed with an โaggressive formโ of prostate cancer that has spread to his bones.
Here is what you need to know about the disease.
Prostate cancer starts in the prostate, a small gland that produces semen fluid. It is the fourth most common cancer worldwide and the second most common among men, with 1.47 million new cases in 2022, according to the UK-based charity World Cancer Research Fund International.
Nations that reported the most cases were the United States, which accounted for 15.7 per cent of the total, followed by China at 9.1 per cent.
In the US, it is the most diagnosed cancer in men after skin cancer, and the second-leading cause of cancer death after lung cancer, with one in 44 dying from it. While it can be serious, most men diagnosed with it survive.
