What increases the chances of developing cancer?
Risk factors for cancer include: older age; lifestyle factors such as smoking, alcohol overuse, poor diet and a lack of physical activity; genetics and family history; viruses and other pathogens (for example, hepatitis B and C viruses and HPV can cause different cancers); chemical exposure - some chemicals such as cigarette smoke and asbestos are highly carcinogenic; radiation exposure (natural radiation such as UV rays from the sun, or man-made radiation from devices such as X-ray machines), and; a weakened immune system.
