Risk Factors
Cancer is a result of complex mix of factors related to heredity, diet, physical inactivity and prolonged, continuous exposure to certain chemicals and other substances. A number of factors that increase a person’s chance of developing cancer has been identified and are called “risk factors”.

Cigarette Smoking
Smoking accounts for more than 85% of lung cancer deaths. Smokers are more likely to develop lung cancer compared to non-smokers. Overall, smoking has been linked to cancers of the mouth, larynx, pharynx, esophagus, pancreas and bladder.

Excessive Alcohol Intake
Heavy drinkers have an increased risk of cancers of the mouth, throat, esophagus, larynx and liver. Some studies suggest that even moderate drinking may slightly increase the risk of breast cancer.

Unhealthy Diet
Diet plays an important role in the development of many cancers, particularly in the digestive and reproductive organs. Long-term habit of not eating a healthy diet has been linked that increases incidence of cancer. Likewise, being seriously overweight has been linked to breast cancer.

Chemicals and Other Substances
Exposure to substances such as chemicals, metals or pesticides can increase the risk of cancer. Asbestos, nickel, cadmium, uranium, radon, vinyl chloride and benzene are well-known cancer-causing agents (carcinogens). These may act alone or together with other carcinogens, like cigarette smoke, to increase the risk of cancer.

Prevention
There is no 100% guarantee that cancer can ever be prevented. However, being aware of the cancer risk factors will help in reducing the possibility of cancer. Early detection and proper treatment plays a big role in controlling cancer.

To lessen the risk of developing cancer:

Quit Smoking
Limit Drinking Alcoholic Beverages
Watch Your Diet
Consult Your Doctor Regularly
Do Regular Physical Activity
