Appendix D: Glossary
Asymptomatic
A woman who does not report symptoms and appears without signs of disease.
Breast cancer
Includes malignant invasive and ductal carcinoma in situ (DCIS) of the breast.
Clinical breast examination (CBE)
A physical examination of the breasts performed by a trained health professional.
Core biopsy
A needle biopsy of the breast used to remove samples of tissue for microscopic evaluation. Most core biopsies are image guided.
Definitive diagnosis
Definitive diagnosis of cancer is the first core or open surgical biopsy that confirms cancer. In rare occasions fine needle aspiration (FNA) biopsy may also be used as a definitive diagnosis of cancer. Definitive diagnosis of benign cases is the last benign test up to 6 months following an abnormal screen.
Ductal carcinoma in situ (DCIS)
A non-invasive tumour of the breast, arising from cells that involve the lining of a breast duct. The cells have not spread outside the duct to other tissues in the breast. DCIS is also referred to as stage 0 cancer.
Fine-needle aspiration biopsy
A needle is inserted into a lesion and cells are drawn out using a syringe. The cells are stained and examined by a cytologist in a laboratory to determine if there are any malignant cells.
Initial screen
The first screening mammogram provided to a women by a Canadian organized breast screening program.
Interval cancer
Any invasive breast cancer diagnosed during the interval between a normal screen or benign diagnostic test and before the next scheduled screening examination.
Invasive cancer
Cancerous cells invading beyond the basement membrane of the milk duct or lobule. A ductal carcinoma in situ component may also be present in cases of invasive cancer. Invasive cancer includes stage I-IV.
Normal screening episode
A screening episode that concludes with normal (non-cancer) findings. This includes both a normal screening mammogram and an abnormal screening mammogram with a normal (non-cancer) finding.
Open surgical biopsy
Surgical removal of a breast abnormality under local anesthesia for subsequent microscopic examination by a pathologist.
Post-screen cancer
Cancers that occur after the recommended 12 or 24 months in women who do not return for their regular annual or biennial screen respectively (non-compliant cancers) or women who become symptomatic before their next regular screen (interval cancers).
Prevalent cancer
The proportion of the population with cancer at a given point in time.
Screen
Includes mammography, or both clinical breast examination and mammography, delivered by a program.
Screening episode (completed)
A normal / negative screening episode is defined as the date of the last screen. For abnormal screens, the screening episode is completed at the date of first pathologic or cytologic (core or open surgical biopsy) diagnosis of cancer. Screening episode completion for benign cases is the last benign test up to 6 months following an abnormal screen. A "negative screening episode" can include all follow-up, provided that the end result is negative (normal).
Rescreening
Subsequent screening after the initial (first) screening under the program. This includes women who return after missing a scheduled round of screening.
Screen-detected cancer
Cancer detected as a result of a positive (abnormal) test with histologic confirmation attributed to the screening findings of the program.
Sojourn time
The time interval between the onset of detectable pre-clinical disease and symptomatic disease.
Total person-years at risk
Within a 12 or 24-month period after a negative (normal) screening episode, women are considered at risk for post-screen detected cancer. Women contribute a count in the denominator for each year or fraction of a year within the period of interest before a post-screen detected cancer or the next regular program screen.
Notes
- Deaths from lung cancer exceed that of breast cancer among women in Canada, with 9,400 deaths expected in 2010.
- Incidence of non-melanoma skin cancer exceeds that of breast cancer in Canada, however, rates are typically not reported due to difficulty estimating true incidence.
- The Evaluation Indicators Working Group Report: Guidelines for Monitoring Breast Screening Program Performance: 2nd Edition is available online at www.phac-aspc.gc.ca
- This value is underestimated because volume counts are not provided to the CBCSD under 50 years or over 69 years of age by some programs for women.
- Indicators for which a change in calculation methodology has occurred include participation rate (30 months), retention rate, diagnostic tests, and post-screen cancer rate resulting in benign diagnosis. Details of the alterations in calculation methods are presented in the relevant results sections.
- Data for opportunistic screening was provided through the Ministry of Health from participating provinces and not obtained from the CBCSD. Opportunistic screening is likely overestimated due to double counting (when screening occurs in both the organized and opportunistic sectors), and incorrect categorization (a proportion of opportunistic bilateral mammograms are preformed on symptomatic women and therefore truly diagnostic).
- Refers to all women including those who may have returned late (≥30 months) from their previous mammogram.
- Non-compliant cancers are not included in this calculation.
