Epidemiology

Prostate cancer is the second-most frequently diagnosed cancer in men, and the second-most frequent cause of cancer death in men (after lung cancer). Around 1.2 million new cases of prostate cancer are diagnosed each year, and over 350,000 people die of the disease, annually. One in eight men are diagnosed with prostate cancer in their lifetime, and around one in forty die of the disease. Rates of prostate cancer rise with age. Due to this, prostate cancer rates are generally higher in parts of the world with higher life expectancy, which also tend to be areas with higher gross domestic product and higher human development index. Australia, Europe, North America, New Zealand, and parts of South America have the highest incidence. South Asia, Central Asia, and sub-Saharan Africa have the lowest incidence of prostate cancer; though incidence is increasing quickly in these regions. Prostate cancer is the most diagnosed cancer in men in over half of the world's countries, and the leading cause of cancer death in men in around a quarter of countries.

Prostate cancer is rare in those under 40 years old, and most cases occur in those over 60 years, with the average person diagnosed at 67. The average age of those who die from prostate cancer is 77. Only a minority of prostate cancer cases are diagnosed. Autopsies of men who died at various ages have shown cancer in the prostates of over 40% of men over age 50. Incidence rises with age, and nearly 70% of men autopsied at age 80–89 had cancer in their prostates.
