We have joined together with one voice to support all women in British Columbia in taking positive steps to reduce their risk of breast cancer.

Other types of contraceptives that are estrogen/progesterone based (topical, injectable, patches, implants, etc.) have been less well-studied. The risk may be similar to oral contraceptives but this has not been proven.
The term “average risk” refers to women who have not had breast cancer and do not have a family history of the disease in a mother, sister or daughter.

Thermography uses sensitive infrared cameras to produce images of temperature variations. Areas with increased blood flow (producing higher temperatures) are considered suspicious. Thermography has a high false-positive rate, and can miss abnormalities that may need further investigation. Furthermore, a suspicious area discovered by thermography will need to be tested further with conventional methods such as diagnostic mammograms or ultrasounds.

It’s important that women understand the possible benefits of mammography, such as early detection of breast cancer and the opportunity to get treatment sooner, and weigh them up against the possible harms. Harms include abnormalities shown on the mammogram that do not turn out to be cancer (a false alarm), but may result in potentially invasive tests such as a needle or open surgical biopsy as well as worry for the woman until the diagnosis is complete.
Your decision to get a mammogram should also be influenced by your chance of developing breast cancer – your chances of developing breast cancer increase as you age.
Number of female breast cancers in 2011 for women 40-69
|40-49||18.1 per 10,000|
|50-59||26.5 per 10,000|
|60-69||42.9 per 10,000|
The Public Health Agency of Canada Decision Aid for Breast Cancer Screening in Canada can help women aged 40 to 79 make an informed decision. You may also choose to have a discussion with a health care provider who can provide you with further information.
