Breast cancer is a cancer that develops from breast cells. Breast cancer usually originates in the inner lining of milk ducts or the lobules that supply them with milk.
In 2020, it is projected that 27 700 Canadians will be diagnosed with breast cancer and 5 100 will die. Since 2004, breast cancer incidence rates have stabilized. This is consistent with recent reports from the US. While stabilized, it is still expected to be the second-highest diagnosed form of cancer, with the fourth-highest number of deaths (Canadian Cancer Statistics, 2020).
There are hundreds of breast cancer organizations in Canada that 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.
