One in two people in the world will develop some form of cancer during their lifetime, experts from the UK's National Health Service (NHS) say. Unfortunately, not every type of cancer is preventable, but it is still possible to reduce the risk of developing it.

The experts recommend keeping active lifestyle to significantly reduce the risk of developing 13 types of cancer. Physical activity helps you lose weight and keep it in check. For example, regular exercise significantly reduces the chances of breast and bowel cancer.

According to scientists, sitting or lying down for long periods of time during the day is unhealthy. Even people who exercise can spend too much time without movement during the rest of the day.
