Using structured breast cancer data

The Centre des Maladies du Sein research team has a comprehensive database of all cancers diagnosed since 1974; more than 12,000 patients are listed. A database of biopsy data from 1999 is also available; data on more than 34,000 biopsies are listed. These databases allow quality publications that modify the management and follow-up of cancers and benign breast diseases.

Offer innovative treatments

The Centre des Maladies du Sein of CHU de Québec-Laval University research group is one of the largest in Canada, offering innovative treatments for breast cancer. More than 50 clinical trials are active at all times and are offered to patients who consult at the clinic or are referred by clinics/hospitals in the area. These clinical trials provide access to innovative experimental medications and develop the expertise of our world-renowned oncologists.

Support the quality of life

The Centre des Maladies du Sein of CHU de Québec-Laval University research group is a pioneer in quality of life studies in breast cancer, from total mastectomy to partial mastectomy, to the use of the cooling cap to counteract hair loss, promoting physical activity to improve survivorship, including optimal preservation of the axillary lymph nodes. The research group is at the forefront of studies promoting quality of life, despite the adverse effects of the disease on an individual’s life.
