BREAST CANCER IN CANADA
Breast cancer is the most common cancer among Canadian women.
Breast cancer incidence is the number of new cases diagnosed in a population over a specific time period.
- In 2007, an estimated 22,300 women in Canada will be diagnosed with breast cancer. On average, that is about 429 women diagnosed every week.
- In 2007, an estimated 170 men will be diagnosed with breast cancer. Men with breast cancer make up a little less than 1% of all cases.
- In 2007, an estimated 5,300 women and 50 men will die from breast cancer.
Breast cancer prevalence is the number of people in a population living with breast cancer at a specific point in time.
- An estimated 162,600 Canadian women who were alive in 2003 had been diagnosed with breast cancer in the previous 15 years.
One in nine (11%) Canadian women is expected to develop breast cancer during her lifetime (this means by age 90), while less than 1% of Canadian men will be diagnosed with breast cancer.
Only one in every 27 Canadian women will die from breast cancer. This means that about two-thirds of the women diagnosed with breast cancer in Canada will live through it.
There is more cause to be optimistic. Since 1999, the incidence of breast cancer in Canada has stabilized. As well, since the mid-1980s, the number of people who die from breast cancer has declined steadily. The biggest improvement in survival has been in the 50 – 69 age group. Higher survival rates have been attributed to improved screening and treatment.
