Researchers at Uppsala University in Sweden have found that artificial intelligence (AI) can be used to identify subtle tissue changes showing prostate cancer long before it becomes visible to pathologists. This could help identify men who have a high risk of developing prostate cancer and who should be screened regularly.

Prostate cancer is the most common form of cancer in men and the third most common cancer in the world after lung and colorectal cancer. Within their lifetime, one in eight men will be diagnosed with prostate cancer, although the global incidence varies greatly. For example, men in Northern Europe and men of African descent have a much higher risk of developing prostate cancer than men of Asian descent.

The risk of developing prostate cancer increases with age.
