Secondary prevention techniques e. During a public health emergency such as the one brought about by the COVID pandemic, when preventive services are likely to see a drop in volume, any underlying disparities in screening uptake in various subpopulations may be exacerbated. Internationally, it has been reported that disproportionately low breast cancer screening participation is seen among women experiencing cultural or immigration-related barriers or in medically underserved communities in the United States. We included all records of women aged 50 to 69 with a valid six-digit BC postal code in service provided during the month period between 1 July and 31 December By means of postal code translation, we assigned a unique census dissemination area DA , health service delivery area HSDA , and health authority HA to each record. By linking screening data with DA-level demographic as well as socioeconomic data derived from Census Plus ,[ 11 ] we examined disparities in breast cancer screening participation among BC women aged 50 to 69 years across HSDAs, across income and education quintiles, and across quintiles of social and material deprivation [ Figure ].

Population-based screening mammography remains the most accessible and scientifically validated test for detecting breast cancer and reducing breast cancer mortality. Downsides of screening include exposure to ionizing radiation, false-positive results, and overdiagnosis. Current screening policy in BC is based on age and other determinants of risk, including family history and genetic factors. For example, routine screening every 2 years is recommended for asymptomatic women age 50 to 74 of average risk, while routine screening every year is recommended for women age 40 to 74 with a first-degree relative with breast cancer. The Screening Mammography Program compiles data for calculating numerous outcomes, including participation and return rates, time to diagnosis measures, and sensitivity and specificity indicators. Breast density is an issue a woman and her primary care provider may need to consider, since normal dense breast tissue may impede detection of cancer.
Breast cancer screening and diagnosis in British Columbia
Breast cancer is the most common type of cancer in women in British Columbia. Breast cancer can occur in men as well, but it is not as common. Tests and treatments for breast cancer vary from person to person, and are based on individual circumstances. Certain factors such as your age, family history, or a previous breast cancer diagnosis may increase your risk of developing breast cancer.
All provinces have breast cancer screening programs for this age range if you are at average risk for breast cancer. Depending on your provincial program, you may be able to make an appointment without a referral or you may need your doctor or nurse practitioner to refer you to the program. Your provincial screening program may not accept women aged 40 to 49 for a screening mammogram where you do not have any symptoms and are not high risk. In that case, you may need to talk to your doctor about the best way to have a mammogram. Some provinces have programs or protocols for women at elevated or high risk.
