Prostate cancer is the second leading cause of cancer-related death for men in both the U.S. and the U.K. This informative video from AsapSCIENCE explains exactly how prostate cancer develops. Using hand-drawn diagrams, the video creators show how normal cells divide, duplicate and grow, and how they receive signals telling them when to stop growing.
Mutations in the cells can lead to them not receiving the signal to stop growing, so they continue to duplicate and change into cancer cells. As a person ages, their cells have more chance of mutating, so this explains why prostate cancer tends to happen to older men and why 80 percent of men have prostate cancer by the time they reach 80.
