MammaCare’s mission is to train every hand that examines a woman, including her own.

MammaCare, the recognized quality-standard for physical examination of the breast, was developed with the support of the National Cancer Institute, the National Science Foundation and medical scientists worldwide.

The contributions of MammaCare scientists and colleagues have been noted in landmark reports on early detection…

Does This Patient Have Breast Cancer? The Screening Clinical Breast Examination: Should It Be Done? How?  Journal of the American Medical Association, 1999 Oct, 6: 283(13), 1687-9.  Barton, M.B., Harris, R. & Fletcher, S.W.

“Our recommendation incorporates practices from the MammaCare method because its components have been validated in independent investigations of CBE technique.” (p. 1276)

How best to teach women breast self-examination. A randomized controlled trial.  Annals Intern Med. 1990 May 15;112(10):772-9. Fletcher SW, O’Malley MS, Earp JL, Morgan TM, Lin S, Degnan D.

Mammacare instruction resulted in more long-term improved lump detection and examination technique use than did traditional instruction or physician encouragement. Breast self-examination instruction should emphasize lump detection skills.

Recent reports confirm that a substantial portion of breast cancer is detected by clinicians’ or  womens’ fingers.

Twenty-five year follow-up for breast cancer incidence and mortality of the Canadian National Breast Screening Study: randomised screening trial. BMJ. 2014 Feb 11;348:g366. doi: 10.1136/bmj.g366. Miller, A. B., Wall, C., Baines, C. J., Sun, P., To, T., & Narod, S. A.

Upon finding that most cancers were palpable at mammography screening visits, Miller et; al. concluded: “From this we infer that if there is benefit from a mammography only screening programme, it is derived through cancers detectable by a thorough breast physical examination.” http://www.bmj.com/content/348/bmj.g366

A significant number of women present with palpable breast cancer even with a normal mammogram within 1 year. Am J. Surg 2010 Dec; 200(6): 712-7. Haakinson DJ, Stucky CC, Dueck AC, Gray RJ, Wasif N, Apsey HA, Pockaj B.

Patients presenting with palpable masses on SBE or CBE even with a normal mammogram within 1 year tended to have more aggressive tumors… resulting in more aggressive therapy.

Most young women detect their own breast cancers…

Patients with palpable presentation were younger than those with screen-detected cancer (mean age 57 versus 62 years…).

Having a lump and both a personal and a family history of breast cancer was the most common reason why women initiated a health care visit.

Self-Detection Remains a Key Method of Breast Cancer Detection for U.S. Women. J Womens Health. 2011 Aug; 20(8): 1135-9. Roth MY, Elmore JG, Yi-Frazier JP, Reisch LM, Oster NV, Miglioretti DL.

Most women survivors (57%) reported a detection method other than mammographic examination.

performance measures…could help to identify clinicians who have a lower sensitivity for CBE and who may therefore require feedback and further training.

…77% of these were true interval cancers, detected clinically in the 1–2 year interval between screening examinations…

Surveillance of women at increased risk of breast cancer using mammography and clinical breast examination: Further evidence of benefit. Int J Cancer. July 2012  ;131(2): 417-25. Andrew Maurice, D. Gareth Evans, Jenny Affen, Rosemary Greenhalgh, Stephen W. Duffy, Anthony Howell

We reviewed its effectiveness in terms of tumour size, lymph node status and survival in 7,475 women seen over a 22-year period in the Manchester Family History Clinic. …. We conclude that screening by annual mammography and CBE between age 35–50 years and 18 monthly from 50 to 60 years may diagnose breast cancer in a less advanced state in terms of size and node status.

Of all tumors, 72% (525/726) were palpable, and 28% (201/726) were nonpalpable. The tumor stage was T1 in 492 patients (67.8%) and T2 in 234 patients (32.2%).

Improved Clinical Breast Examination Competencies Via Intelligent Simulator Training, July 7, 2012   Meeting of the German Society for Senologie, Stuttgart Goldstein M.K.*, Mehn M.A.*, Pennypacker H.S.*, Brost B.C.** Petersen W.O.**, Nicometo A.M.**,  MammaCare* and Mayo Clinic**

Two independent trials found that the CBE Simulator produced significant gains in clinical breast examination skills suggesting that this technology may improve the accuracy and quality of breast cancer screening.
