Recommended by expert medical guidelines

MammaPrint is included in numerous clinical practice guidelines developed by world-recognized cancer care organizations. Clinical guidelines are evidence-based recommendations for healthcare professionals involved in the management of patients.

Guidelines aim to improve the quality of care and services based on the most up to date peer-reviewed evidence. For example, MammaPrint is the only test of its kind endorsed by the American Society of Clinical Oncology for lymph node-positive patients.

Also included in the National Comprehensive Cancer Network® (NCCN®).

I kept thinking maybe I’d made the wrong decision, maybe I should have had a mastectomy. MammaPrint allowed me to calm down, refer back to my results, and return to the faith I had in my treatment.— Mary, a breast cancer survivor

*Randomization is a procedure to allocate clinical study participants into different groups. By using chance to allocate participants, the groups are likely to be similar and allow the effects of the treatments to be compared more fairly.When patients are recruited to a clinical study and followed forward in time.A type of clinical trial designed to confirm and expand on the safety and/or effectiveness of an intervention from earlier clinical trials. Phase III trials are often large and may consist of hundreds or even thousands of patients.
