Rapid genetic counseling and testing in newly diagnosed breast cancer: Patients' and health professionals' attitudes, experiences, and evaluation of effects on treatment decision making.

Background: Rapid genetic counseling and testing (RGCT) in newly diagnosed high-risk breast cancer (BC) patients may influence surgical treatment decisions. To successfully integrate RGCT in practice, knowledge of professionals', and patients' attitudes toward RGCT is essential.

Methods: Between 2008 and 2010, we performed a randomized clinical trial evaluating the impact of RGCT.

Impact of rapid genetic counselling and testing on the decision to undergo immediate or delayed prophylactic mastectomy in newly diagnosed breast cancer patients: findings from a randomised controlled trial.

Background: Female breast cancer patients with a BRCA1/2 mutation have an increased risk of contralateral breast cancer. We investigated the effect of rapid genetic counselling and testing (RGCT) on choice of surgery.

Methods: Newly diagnosed breast cancer patients with at least a 10% risk of a BRCA1/2 mutation were randomised to an intervention group (offer of RGCT) or a control group (usual care; ratio 2 : 1).
