Risk Factors

The factors in the body that trigger the probability of suffering from a disease are referred to as risk factors. For example, an excessive increase in an individual's body weight can trigger the chances of getting heart disease. Similarly, if an individual is exposed to carcinogenic substances, it increases the probability of suffering from cancer. These factors can pose a severe threat to the overall health of an individual.
