Health sa国际传媒 is warning Canadians and their health-care providers that thermography machines are not approved for use in sa国际传媒 for breast cancer screening.
The department says it is not aware of any scientific evidence that supports use of the thermal imaging machines as a screening tool for early detection of breast cancer.
Health sa国际传媒 says there could actually be a potential risk to women if they rely on thermography results.
It's suggested that women who have used thermal imaging for breast screening contact their doctors for appropriate follow-up and testing.
Health sa国际传媒 says it is contacting manufacturers of the devices to ensure they know that it is illegal to advertise or sell these types of machines to screen for breast cancer in sa国际传媒.
The department is also working with the sa国际传媒 Border Services Agency to stop any unlicensed devices from entering sa国际传媒.
Health sa国际传媒 says it will be notifying provincial and territorial ministries of health that clinics that fall under their jurisdiction should not be promoting or using thermal imaging machines for breast cancer screening.
Manitoba Health Minister Theresa Oswald has already ordered a thermog-raphy clinic in Winnipeg to stop operating.
The Canadian Breast Cancer Foundation is also joining the information effort.
The foundation is telling Canadians that thermogra-phy is not recommended by any medical authority or leading cancer organization.
Thermography uses a heat-sensitive infrared camera to take images of the body and detect blood flow pattern. Some breast thermography clinics, which charge consumers for the service, claim the images the machines generate can be used to detect breast cancer.
