Carriers of a BRCA mutation have a significantly increased risk to develop breast cancer in the course of their lives . They face a difficult choice: either a preventive removal of the breast(s) or an intensive inspection process.

After primary treatment of breast cancer, patients will be followed for 5-10 years to diagnose recurrence or a new primary tumor in an early stage; to support the patient during hormonal treatment; to educate the patient about risk factors and healthy life style; and to provide psychosocial support.

Currently, follow-up of breast cancer patients and surveillance of BRCA mutation carriers is offered in regular, one-to-one medical visits. Experience shows that in an individual visit it is often not possible to give all aspects that are important, enough attention. The group medical consultation (GMC) is a new form of medical visits where the physician or nurse practitioner performs a series of one-to-one consultations in the presence of 8 to10 other patients. A social worker accompanies this process. Patients in group consultations may gather more information because they learn from each other and there is relatively more time compared to a regular consultation. Research shows that both patients and caregivers are more satisfied with care after a group consultation compared to individual visits. After a GMC the participants from the breast cancer GMCs will be provided with a dedicated iPad for 3 months. Using this iPad, patients can contact the women they have met during the GMC as well as health care professionals by several communication channels, including virtual group meetings. This approach provides a unique combination of both social support and professional education concerning survivorship in an e-health environment.However, it is also known that group sessions may be counterproductive for some patients, for example because they are frightened by the stories of others. The goal of this study is to examine whether group visits (in combination with dedicated iPads) are beneficial to women with a BRCA mutation and for patients in follow-up after breast cancer.
