Breast Cancer Facts
  • Breast cancer is the most common cancer in Canadian women, with one in nine women expected to be diagnosed with it in their lifetime.
  • In 2014, it is estimated that about 9,800 Ontario women will be diagnosed with breast cancer and that 1,900 will die from this disease.
  • Breast cancer occurs primarily in women 50 to 74 years of age (57% of cases)
  • Most women diagnosed with breast cancer have no family history of the disease.
  • Less than 1% of women in the general population are estimated to be at high risk for breast cancer.
  • There is no way to prevent breast cancer yet, but if breast cancer is found early, when it is very small, there is a good chance it can be cured.

Reduce the Risk of Breast Cancer

A healthy lifestyle can reduce the risk of breast cancer. Women should:

  • Avoid alcohol or have no more than one alcoholic drink per day
  • Limit their time on hormone replacement therapy, if used, and talk with their family doctor or nurse practitioner before making any medication changes
  • Maintain a healthy body weight, especially after menopause
  • Be physically active as part of everyday life
  • Get screened—regular mammograms, generally every two years, are the best way most women aged 50 to 74 years can reduce the risk of dying from breast cancer
