The most cost-effective long-term strategy for cancer control is prevention. Cancer prevention is the action taken to lower the risk of getting cancer. This can include behaviors, such as minimizing exposure to tobacco, maintaining a healthy diet, exercising regularly, practicing healthy sexual behaviors, and protecting against excess UV light exposure. Additional cancer prevention modalities include implementing environmental regulations, promoting or requiring selected vaccinations, treatment of diseases that predispose one to cancer, and population-based cancer screening.
