Governments implement a variety of policies to promote cancer prevention and reduce the incidence of the disease. Public health campaigns aimed at reducing tobacco use, promoting healthy diets, and encouraging regular physical activity are central to these efforts. Additionally, governments often regulate substances known to cause cancer, such as banning specific carcinogens in consumer products. Vaccination programs, such as those for the human papillomavirus (HPV), are also crucial government-led initiatives. By providing or subsidizing vaccines, governments can significantly lower the risk of certain cancers, notably cervical cancer, within the population.
