Prostate cancer is the most commonly seen cancer in men, but it is not the most deadly. It is the 3rd cause of death from cancer, after lung cancer and colorectal cancer.
Closely linked to age, prostate cancer is rare before the age of 50, and the highest number of cases are in men around 70 years of age.
Its aggressiveness varies: some cancers evolve slowly and without symptoms, while others evolve rapidly towards locoregional invasion and metastases. As a general rule, no signs or symptoms are seen during the early stages of the disease.
