Smoking Tobacco causes many types of cancer, including cancers of the lung, oesophagus, larynx, mouth, throat, kidney, bladder, pancreas, stomach. Smokeless tobacco causes oral, oesophageal and pancreatic cancer.
About 70% of the lung cancer can be attributed to smoking alone. Second-hand smoke has been proven to cause lung cancer in non-smoking adults.
Physical inactivity, dietary elements, and obesity.
Dietary alterations are an important method to control cancer. There is a link between overweight and obesity to many types of cancer such as oesophagus, colorectal, breast, and kidney.
Diets high in fruits and vegetables may have a protective effect against many cancers. Similarly, additional consumption of red and preserved meat may be linked with an increased risk of colorectal cancer.
Regular physical activity and the maintenance of a healthy body weight, along with a healthy diet, will considerably reduce cancer risk.
Infections like Viral hepatitis B and C cause cancer of the liver; human papilloma virus infection causes penis, anus and oropharynx cancer; the bacterium Helicobacter pylori present in the stomach can increase the risk of stomach cancer. Preventive measures include vaccination and prevention of infection.
Exposure to cancer-causing chemicals in the environment can occur through drinking water or pollution of indoor and ambient air. Exposure to chemicals also occurs via the contamination of food by chemicals, air pollution can double the risk of lung cancer.
Ultraviolet (UV) radiation is dangerous to humans, causing all major types of skin cancer, such as melanoma cancer. Avoiding excessive exposure, use of sunscreen and protective clothing are effective preventive measures.
