There are many different types of cancers. All of them are characterized by uncontrolled growth and spread of abnormal cells in some part of the body.

An estimated 149,000 new cases of cancer and 69,500 deaths from cancer will occur in Canada in 2005. The most frequently diagnosed cancer will continue to be breast cancer for women and prostate cancer for men. The leading cause of cancer death for both sexes continues to be lung cancer.

Health Canada in partnership with the Public Health Agency of Canada, continues to monitor this disease, identifying the trends and the risk factors, developing programs to reduce cancer risks, and undertaking research to evaluate risks from the environment and behaviours.

Facts on cancer

Risk Factors

There are many known risk factors for cancer:

Tobacco Use is the cause of almost 30% of all fatal cancers in Canada and a major cause of lung cancer, one of the most preventable cancers.
Poor Diet -- one with a high proportion of dietary fat -- causes about 20% of fatal cancers. Colon and prostate cancers are associated with diets high in fat.
Other Risks include workplace hazards, family history, alcohol use, reproductive factors, sexual activity, sunlight, drugs, and ionizing radiation.
Behavioural Factors
Environmental Factors
- Assessment and Management of Cancer Risks From Radiological and Chemical Hazards (report of a joint working group of Health Canada and the Atomic Energy Control Board)
- Screening and other early detection practices help identify cancers in their early stages, when treatment can be more effective. Consult your physician.
