EPA has since gained considerable experience in applying cancer risk assessment approaches. Some group 1 carcinogens cause aggressive, untreatable tumours; for others, such as human papillomavirus, disease is largely preventable by screening; still others, such as sunlight, sometimes cause serious disease but mostly cause relatively minor tumours. Tobacco smoking and asbestos are also both classified as carcinogenic to humans(Group 1). PAHs can be swallowed, breathed in, or in some cases, pass through the skin.
