Final answer:
Chronic noninfectious diseases like cardiovascular diseases, cancer, diabetes, and stroke are significant contributors to health-related costs and are largely lifestyle-related, hence preventable to a large extent.
Step-by-step explanation:
Heart disease, stroke, and diabetes are mostly linked to lifestyle choices, and together with cancer, these chronic noninfectious diseases contribute to over a third of the total cost of diseases to society. They are considered largely preventable through lifestyle changes and early detection strategies. Cardiovascular diseases, including coronary artery disease and stroke, are particularly significant contributors to disease-related costs and are the leading cause of death globally. Many of the risks associated with these diseases, such as obesity, smoking, and lack of exercise, can be modified, which shows the potential for reducing the burden of these diseases through public health interventions and individual lifestyle changes.
