Stony Brook Southampton Meeting House

On March 3, 2023, Michelle Annette Wintjen, a licensed Family Nurse Practitioner, became certified as a MammaCare Clinical Breast Examiner for the Stony Brook Southampton Hospital, Meeting House Lane Medical Practice in New York

Studies of breast cancer symptoms in national healthcare programs confirm that a lump is the earliest and most common sign of breast cancer. It is also known that in between screenings, self-detected breast lumps reveal cancers missed by mammograms. Examinations by practitioners with documeted palpation skills are trained to thoroughly evaluate patient-detected lesions. Certified clinical breast examiners with verified skills are a first line of care reccomended for women with elevated risk risk of breast cancer.

The MammaCare Method of breast examination is the result of decades of research supported in part by the National Cancer Institute and National Science Foundation. It is the recognized standard for practice and training for clinical breast exams skills, competencies and certification. The skill-based program involves guided practice and performance measurement on tactually accurate breast models and on live surrogates. 

Graduates like Mrs.Wintjen earned certification as a MammaCare Clinical Breast Examiner via live, guided, online practice and training in which clinicians meet rigorous performance standards of sensitivity, specificity and exam thoroughness. 

“The MammaCare method is systematic and organized. Obtaining MammaCare training and certification has equipped me with the skills and confidence I need to provide the best possible clinical breast exam to my patients. I look forward to putting it into practice.”

- Michelle Wintjen, FNP, CBE-MC
