What are Some Examples of Successful Prevention Programs?

Several prevention programs have demonstrated significant success, such as:

Immunization programs that have eradicated diseases like smallpox and significantly reduced the incidence of polio and measles.
Screening programs for cancers, such as mammography for breast cancer and colonoscopy for colorectal cancer, which have led to early detection and better survival rates.
Public health campaigns targeting smoking cessation, healthy eating, and physical activity to reduce the risk of chronic diseases.
