Cancer risk factors refer to certain behaviors, exposures, or genetic characteristics that increase the likelihood of developing cancer. These risk factors can be divided into several categories, including lifestyle factors such as tobacco use, poor diet, and lack of physical activity; environmental factors such as exposure to carcinogens or radiation; genetic factors such as inherited mutations that increase cancer risk; and other factors such as age, gender, and family history of cancer. Researchers study cancer risk factors to better understand the underlying causes of the disease and to identify ways to prevent or reduce cancer incidence. By identifying and addressing modifiable risk factors, individuals can take steps to reduce their risk of developing cancer. Identifying non-modifiable risk factors can also help healthcare providers target screening, monitoring, and prevention efforts for individuals at higher risk.
