For example, when discussing cancer risk, you may discuss the chance of developing cancer versus the chance of not developing cancer. The time period is how far in the future the risk level extends. The longer you wait for an event, the more likely it is to happen. For example, you might have a low chance of developing cancer this year, but you have a much higher chance of developing cancer during your lifetime. So when your risk is presented over a long time period, it might seem higher to you than the same risk presented over a shorter time period.
