Breast Cancer Screening Programs and Guidelines

Organized breast cancer screening programs are available in most provinces and territories across Canada. The programs screen women who are asymptomatic (no signs or symptoms of breast cancer present) and at average risk for breast cancer. Where organized screening programs are not available, screening services may be provided opportunistically through a primary care provider.

Breast Cancer Screening Programs and Guidelines – Highlights

Breast Cancer Screening Programs in Canada (refer to slide #7)• The first organized breast cancer screening program began in British Columbia in 1988. From

1990 to 2008, 11 more provinces and territories started organized breast cancer screening programs. Nunavut does not have an organized breast cancer screening program.

Provincial and Territorial Breast Cancer Screening Clinical Practice Guidelines (refer to slide #10-12)• Most provinces and territories recommend screening women at average risk with a mammogram

every two years at age 50, and continue until age 74 or 75. Some provinces and territories accept women at ages <50 to screen for breast cancer, every one or two years, if a woman chooses to get screened, has been identified as high risk, or has a physician recommendation.

Breast Cancer Screening Recruitment Methods (refer to slide #13)• Most provinces and territories (with the exception of Nunavut) recruit women into their breast

cancer screening program with a physician referral or self-referral. Additionally, six provinces require an initial invitation letter to be accepted into the screening program.

Canadian Task Force on Preventive Health Care Guidelines (2011), cont’d

Additional breast cancer screening recommendations by the Canadian Task Force on Preventive Health Care (2011) include:

Mammography• Mammography screening for women aged 40-49 is not recommended for routine screening for

breast cancer

Magnetic Resonance Imaging• Magnetic resonance imaging is not recommended for routine screening for breast cancer

Clinical Breast Exam• Clinical breast exam alone or in conjunction with mammography is not recommended for

routine screening for breast cancer

Modalities for Breast Cancer Screening

The modality commonly used as an entry level screening test for breast cancer is mammography. All provinces and territories (with the exception of Nunavut) perform mammography screening within organized screening programs. Currently, no province or territory recommends clinical breast examinations. Other modalities may include tomosynthesis or MRI, and their use may be dependent on a woman’s risk level.

Modalities for Breast Cancer Screening – Highlights

Mammography Screening Technology (refer to slide #16-17)• All provinces and territories (with the exception of Nunavut) are currently using digital

radiography (DR) equipment to screen women in their programs. In addition, two provinces and one territory are using computed radiography (CR), as well as DR equipment. Only two provinces are using analog mammography (screen-films) in conjunction with DR and/or CR.

Other Breast Cancer Screening Modalities (refer to slide #18-19)• Other modalities used in Canada to screen women for breast cancer are tomosynthesis,

magnetic resonance imaging (MRI) and ultrasound. Tomosynthesis is being used in four provinces (BC, AB, QC and NB). Ontario screens women at high risk for breast cancer using MRI or ultrasound through the Ontario Breast Screening High Risk Program.

Correspondence Methods and Follow-Up for Breast Cancer Screening

Recall letters or other forms of communication are used to notify women who have been screened by the program in the past to return for screening. Women who have a normal screening result are invited back at regular intervals (as per provincial/territorial screening guidelines) for subsequent screening. Women who have an abnormal screening result are invited for follow-up.

Correspondence Methods and Follow-Up for Breast Cancer Screening – Highlights

Recall Following a Normal Mammogram (refer to slide #23-24)• All provinces and territories (with the exception of Nunavut) send out recall letters or a

postcard to women after they obtain a normal mammography result. In addition, a follow-up letter is sent if there has been no reply to the initial recall letter (excludes Nunavut and Yukon). Most provinces and territories send out reminder notifications via letter if no response was received after the first communication.

• The target age group for recall of a normal result varies across Canada where the majority of the provinces target women ages 40-74 (four provinces and one territory) and ages 50-74 (five provinces).

Correspondence Methods and Follow-Up for Breast Cancer Screening – Highlights, cont’d

Follow-Up After an Abnormal Mammogram (refer to slide #25-28)• All provinces and territories (with the exception of Nunavut) send recall letters to both the primary

care provider and women after an abnormal (positive) mammography result is obtained. Some provinces and territories contact women by phone for informing them about their result and/or booking a follow-up appointment.

• In the absence of a primary care provider, seven provinces help women find a suitable primary care provider in order to be followed-up after an abnormal mammography result. NWT, YK and BC require a primary care provider prior to being eligible for a screening mammogram. In PEI, either the provincial coordinator or Medical Director/Surgeon directly call women with the abnormal mammography result.

• When a woman cannot be reached (e.g. return mail), most provinces and territories contact and notify the primary health care provider or obtain current contact information from the primary health care provider; furthermore, some provinces and territories try to contact the woman by telephone or letter; two provinces check for an alternate source to locate a recent address.

• The location for conducting diagnostic mammograms after an abnormal result vary across Canada. Five provinces and one territory performs diagnostic mammograms at Diagnostic Breast Imaging Centres. Five provinces and one territory performs such mammograms at the screening centre/program and four provinces refer women to Breast or Risk Assessment units.

Breast Cancer Screening in Canada for Women at Elevated Risk

Women at elevated risk are individuals who are not considered average risk or high risk. This may include women who have a family history of breast cancer, have high breast density, used hormone replacement therapy in the past and/or are at high risk for benign breast disease. This differs from women at high risk who have a greater lifetime risk of developing breast cancer and/or developing more aggressive breast cancers at an earlier age.

Breast Cancer Screening in Canada for Women at Elevated Risk – Highlights

Definition of Elevated Risk (refer to slide #31-32)• Two provincial and one territorial screening programs define elevated risk as having first-degree family history

of breast cancer, using hormone replacement therapy, having a breast density of ˃75% or ≥75%, having a history of high risk benign breast disease and having a recommendation by a radiologist. Some provincial/territorial programs only have one to four of these characteristics listed to define elevated risk. There are other characteristics that are also listed by some provincial/territorial programs and include: having personal or first-degree family history of ovarian cancer (NWT, MB, ON), Ashkenazi ancestry with any family history (MB) and first or second-degree family history of male breast cancer (MB).

Management of Elevated Risk by Screening Program (refer to slide #33-34)• There are seven provincial and one territorial screening programs (with the exception of Nunavut) that screen

women at elevated risk. The screening protocol most commonly recommended to women at elevated risk is a mammogram every year. Across Canada, the age group to start and stop screening women at elevated risk varies where the age groups are 40-74 (two provinces/one territory), 50-74 (three provinces), 69-74 (one province) and 40+ (one province). For the provincial/territorial programs that do not directly manage women at elevated risk, the follow-up strategies differ.

Referral for Elevated Risk (refer to slide #35-36)• There are six provinces and one territory that manages women at elevated risk through their screening

programs. For the provinces that do not manage women within their programs, they refer women to: their family physician (AB, QC, NB), a surveillance program (AB, PEI) or a diagnostic centre (NB).

Breast Cancer Screening in Canada for Women at High Risk

Women at high risk have a greater lifetime risk of developing breast cancer and/or developing more aggressive breast cancers at an earlier age. Currently, there are no national guidelines for screening women at high risk and screening protocols vary across jurisdictions.

Definition of High Risk (refer to slide #39-42)• The Ontario Breast Screening Program (OBSP) screens women at high risk through their high risk screening

program by meeting the following eligibility criteria: known carriers of a deleterious gene mutation (e.g. BRCA 1/2 mutation), first-degree relative of a mutation carrier (e.g. BRCA 1/2 mutation) and have declined genetic testing, at ≥ 25% lifetime risk of breast cancer (must be assessed by using IBIS or BOADICEA risk assessment tools) and received chest radiation before the age of 30 and at least eight years previously. Five provinces include the same characteristics listed in the OBSP high risk eligibility criteria. Four provinces include two or three out of the four characteristics to define women at high risk.

Management of High Risk by Screening Program (refer to slide #43-44)• Six provincial screening programs screen women identified at high risk by recommending mammography

screening every year (BC, MB, NS, PEI, ON) or every two years (QC). Depending on the province, guidelines recommend that women at high risk start screening at age 30, 40 or 50 and continue screening until age 69 or 74. In Ontario, women at high risk are also screened annually with MRI (or ultrasound if MRI is contraindicated).
