Which of the following is a characteristic of secondary disease prevention?

Secondary disease prevention focuses on early detection and prompt treatment of diseases to reduce severity and prevent complications. Screening for diseases, such as mammograms for breast cancer or colonoscopies for colorectal cancer, is a key component of secondary prevention. By identifying a disease at an early stage, individuals can receive timely interventions that may mitigate the disease's impact and improve outcomes.

While vaccination to prevent disease is a form of primary prevention, treatment to reduce disability pertains more to tertiary prevention, which deals with managing and minimizing the effects of existing disease. Promotion of a healthy lifestyle is also considered part of primary prevention, aiming to avert the onset of diseases altogether. Thus, the identification of disease through screening encapsulates the essence of secondary prevention, making it the correct choice.
