Dense breast tissue is a risk factor for breast cancer. According to the Canadian Cancer Society, women with dense breast tissue have a higher risk of developing breast cancer than women with little or no dense breast tissue.
At Mayfair Diagnostics all of our mammogram machines use 3D mammography (tomosynthesis) and are equipped with software that classifies breast density, which is included in reports to referring doctors.
You can’t tell by looking at them, whether or not you have dense breasts. It is a clinical diagnosis that can only be assessed by mammography. Dense breasts have less fat and more glandular and connective tissue. Unfortunately, they also make a mammogram harder to read, so smaller cancers may be hidden. Plus, the denser the breast tissue, the higher the risk of breast cancer.
On a mammogram, fatty tissue looks dark, while both dense tissue and tumours look white, making it hard to distinguish between the two. The white-looking breast cancers are easier to see on a mammogram when they’re surrounded by dark-looking fatty tissue.
Dense breasts are normal. Your breast tissue changes as you age, usually becoming less dense as you get older and go through menopause, but some women continue to have dense breast regardless of age. Dense breasts may be affected by taking hormone replacement therapy.
To determine your breast density, you will need to discuss scheduling a mammogram and a review of the results with your health care provider.
The Breast Imaging Reporting and Database Systems, or BI-RADS, classifies breast density into four groups:
While scoring is not an exact science and radiologists often disagree about levels of density, it is important to get screened. Mayfair uses Volpara software, which scores density from A to D. We will also explain your breast score at the end of your appointment, if requested.
When an assessment determines that breast density is high, the radiologist may suggest annual mammography exams. In addition, the radiologist may suggest the use of handheld or automated breast ultrasound (ABUS) in conjunction with your regular screening mammogram.
Mammography views the breast in slices and provides a greater level of detail, while breast ultrasound increases the sensitivity of the scan. In Alberta, the Toward Optimized Practice Breast Cancer Screening Guidelines suggest that ultrasound “May be used as a supplemental tool by a radiologist after considering current and prior imaging (if available), and history.” You will need to discuss your results and next steps with your health care provider.
Mayfair has 13 mammography clinics in Calgary and one in Cochrane. We also have 13 ultrasound locations in Calgary and one in Cochrane, which offer breast ultrasound services. ABUS is offered at our Market Mall, Mayfair Place, Southcentre, and The CORE locations.

Radiologists are specialized physicians who interpret diagnostic imaging to diagnose and monitor a wide range of medical conditions. At Mayfair Diagnostics, they review X-ray, ultrasound, CT, and MRI studies, among others, analyzinsg images in detail and providing comprehensive reports and clinical recommendations to referring physicians. They collaborate closely with technologists and clinic teams to guide imaging protocols, ensure quality and radiation safety standards, and may perform image-guided procedures such as biopsies or injections. Through their expertise and teamwork, radiologists play a key role in accurate diagnosis, effective treatment planning, and improved patient outcomes.
Administrative professionals support the organization across human resources, marketing, operations, strategic partnerships, finance, information technology, and infrastructure. From recruiting staff to promoting services and improving workflows, they help ensure smooth operations and positive experiences for employees and patients. Through collaboration with clinical and support teams, they provide essential coordination that enables efficient, high-quality service.
Diagnostic Imaging Assistant (DIA) support clinic operations and help ensure a positive patient experience. They assist staff by greeting and preparing patients, confirming information, coordinating appointments, and guiding patients through their visit. DIAs also maintain exam rooms, manage documentation, and ensure supplies and equipment are ready. Through strong customer service, attention to detail, and teamwork, they help create a safe and organized environment.
Patient Experience Coordinators (PECs) are the first point of contact, scheduling exams and ensuring accurate patient information. They communicate clearly with patients, coordinate with care teams, and support a smooth, confidential, and customer-focused experience.
Nuclear Medical Technologists perform diagnostic nuclear medicine procedures involving sensitive and highly personal patient circumstances. They are responsible for delivering the highest standard of care in a professional, compassionate, and patient-centered manner, in accordance with provincial regulatory requirements, CAMRT standards, and Mayfair policies and guidelines.
Computed Tomography (CT) Technologists operate CT imaging equipment to produce detailed cross-sectional images of the body that assist in diagnosing a wide range of medical conditions. They prepare and position patients for scans, ensure safety protocols are followed, and administer contrast agents when required. CT technologists work closely with radiologists to ensure high-quality diagnostic images are obtained, while providing clear communication and compassionate care to support patient comfort throughout the procedure.
Magnetic Resonance Imaging (MRI) Technologists operates MRI scanners to produce detailed images of internal body structures used to assist in medical diagnosis and treatment planning. They are responsible for preparing and positioning patients, ensuring all safety protocols are strictly followed due to the strong magnetic field, and obtaining high-quality images as directed by radiologists. MRI technologists combine technical expertise with patient care, providing clear communication and support to ensure a safe, comfortable, and efficient imaging experience.
Diagnostic Medical Sonographers perform ultrasound exams to help diagnose and monitor medical conditions. Following Sonography Canada standards and Mayfair Diagnostics protocols, they capture accurate images while ensuring patient safety, comfort, and confidentiality. They work with radiologists and clinical teams to review requisitions, prepare patients, perform scans, and document findings, contributing to accurate diagnoses and a positive patient experience.
Medical Radiation Technologists (MRTs) perform x-ray, mammography, and BMD exams while ensuring patient safety, accuracy, and compassionate care. They also may assist in pain therapy procedures. MRTs verify patient information, explain procedures, position patients, and produce high-quality images. MRTs follow professional standards and protocols, maintaining strict radiation safety, quality assurance, and patient privacy while supporting a positive patient experience.
