Cancer prevention and screening

The research group conducts national and international research in population-based screening for colorectal cancer in general, and, specifically, evaluation of the ongoing screening program of the Stockholm-Gotland healthcare region. The ambition is to increase cooperation with researchers and co-workers involved in other screening programs to contribute in quality assurance and screening activity improvement.

The group is also involved in a multinational study (I-SCAN) to quantify cancer risk in patients with inflammatory bowel disease (IBD). The aim of the study is to develop a risk stratification model to be able to optimize treatment and surveillance for the individual patient and the cost-effectiveness of clinical guidelines.

The research group is part of the Department of Clinical Science and Education at Södersjukhuset with close collaboration with the Departments of Molecular Medicine and Surgery (MMK), Laboratory Medicine (LABMED), and Medical Epidemiology and Biostatistics at Karolinska Institutet (MEB).

Breast Surgery

The Breast Cancer Unit at Södersjukhuset is one of the largest breast cancer units in Sweden. Plastic surgeons and breast surgeons work together in close collaboration with oncologists, pathologists, and radiologists to provide evidence-based care to breast cancer patients in Stockholm. The surgical team in the Breast Cancer Unit is nationally recognized for its extensive experience in oncoplastic surgery and breast reconstruction.

Within the unit, clinical and register-based research is conducted within the field of breast cancer, in partnership with other departments and institutions. The unit frequently participates in national and international clinical studies within breast surgery.
