Disease risk research involves studying the factors and variables that increase an individual's likelihood of developing a particular disease. This can include genetic predispositions, environmental exposures, lifestyle choices, and other demographic or health-related factors. Researchers in this field aim to better understand the causes and mechanisms of disease development, in order to develop strategies for prevention, early detection, and treatment. By identifying and analyzing disease risk factors, researchers can inform public health policies and interventions to reduce the burden of illness on individuals and populations.
