Major causes of Cancer



Major causes of cancer, as identified by the joint Cancer Care Ontario / Canadian Cancer Society, Ontario division report Cancer 2020 summary report are:

  • Tobacco use
  • Diet, obesity and inactivity
  • Occupation and environment
  • Family History
  • Other Factors (biological agents, reproductive factors, radiation & sunlight, alcohol, socio-economic class, drugs, food additives/contaminants)

In 2001, the most frequently diagnosed cancer continues to be breast cancer for women and prostate cancer for men. The leading cause of cancer among both sexes continues to be smoking.

The majority of these cancers occur because of lifestyle or environmental factors. These factors can easily be changed! When we adopt new, healthy behaviours that focus on cancer-prevention, we lower our risk of cancer by up to 70%.
