Breast cancer is a cancer that develops from breast cells. Breast cancer usually starts off in the inner lining of milk ducts or the lobules that supply them with milk. Since 2004, breast cancer incidence rates have stabilized. This is consistent with recent reports from the US.
As of June 2017, there have been an estimated 26,500 new cases of breast cancer and an estimated 5,000 breast cancer deaths in Canada (Canadian Cancer Statistics, 2017). There are hundreds of breast cancer organizations in Canada, many which provide information, support, raise funds for research, or provide services to specific populations; such as young women, women living with metastatic breast cancer, rural women, etc.
