Breast Cancer Screening Prevention


These basic statistics highlight the importance of screening and early detection for all women  between the ages of 25 and 90+.  Breast cancer is common, serious and silent in the early stages though is highly curable when found  in time.


Indeed, this is the slogan of the American  Cancer Society.  Early detection is truly the key to success and cure.  Stage 0, I and II node-negative breast cancers are by far the easiest to treat with generally excellent  (90%+) long-term survival rates.

Many think  that family history,  personal  history,  environment, identifiable gene mutations (BRCA 1,2), age at first pregnancy, or lack of breast feeding are the major  risk factors contributing to breast cancer.  These factors do play a role, yet the 3 main risk factors applicable to most women for acquiring breast cancer are:

1.    FEMALE GENDER (Males rarely acquire breast cancer)

2.     AGE


How to Early Detect?

Screening for all women  of appropriate age is the key.  Our best research supports the following methodologies:

1.    SBE (Self Breast Exam) done properly and consistently

2.    PBE (Professional  Breast Exam)

3.    Mammography

4.    Breast Ultrasound (Sonogram) of both breasts

It is estimated that 15% of women  find their  own breast cancers with SBE, 50% are detected by Mammography and 30 to 40% by Sonography  (Ultrasound).  MRI is useful in special circumstances but is not practical  for screening due to excessive cost (also not covered by insurance) and the requirement for radioactive IV contrast material (long-term safety not established).   Note that by combining SBE, PBE, Mammography and Ultrasound the likelihood of finding a given breast cancer in the early stages (node-negative) is 90+%.

Evidence Based Care…

We advocate for and utilize common sense, evidence based guidelines  seasoned with clinical judgment and individualized care.  Nothing is cookbook or cast in stone.

The landmark work of Johns Hopkins  University,  the endorsement of the American College of Radiology and the Society for Breast Imaging attest to the proper use of ultrasound for breast screening in appropriate candidates according  to risk status.

Breast Density  Law…

California law SB 1538 as of April 2013 and many other  states now require women who have heterogeneously dense and/or extremely dense breasts (the majority of the population) to be informed of this condition and in turn  be offered additional screening tests if desired.  The additional most practical  test is bilateral (both breast) ultrasound due to its safety, effectiveness and low cost.

Schools of Thought…

To screen or not to screen?  There really is no true debate on this issue.  Of course screening saves lives when done properly. Just as prenatal care, dental care, adult check ups, blood  pressure, diabetes  and cholesterol screening save lives and improve our quality  of life when performed appropriately. The screening simply must be evidence-based,  of high quality, accessible and affordable.

How and When to Screen:

Regarding age and the decades of life we advocate for the following: Teens:  SBE

·         20-30 years:  SBE

·         30-40 years:  SBE, Breast Ultrasound

·         40-80 years:  SBE, Breast Ultrasound, Mammography

·         80 years plus:  same as 40-80 if one has 5 or more years of life expectancy

The time interval (frequency)  is generally  once per year unless high risk…then consider  every 6 months for Ultrasound.

Accuracy of Screening…

When SBE, PBE, Mammogram and Bilateral  Ultrasound are combined in the proper interval,  most (90%) of breast cancers are found  in stage 0, I or II and are lymph node negative (excellent prognosis).

What about false positives and so-called  ‘unnecessary biopsies’?

This is not an issue when careful risk assessment, appropriate high-quality screening and follow-up are conducted in an evidence based, individualized manner.

Who Conducts the Clinical  Testing?

Full time gynecologist and women’s health specialist, John Armstrong MD MS Inc. personally conducts  the PBE, the ultrasound examination and interprets the study for you in real time at the visit.  There is no waiting  for your result or interpretation. He has extensive training and experience in the examination and clinical correlation of the findings (what to do with the results and how to use the information).  Dr. Armstrong has 34 years of post-training experience in breast health having conducted approximately 8000 ultrasound examinations with  accurate interpretations to date. We have state of the art, high-definition Toshiba Ultrasound equipment and each study is hand-held rather than automated by a robot or obtained by a technician.  This technique of real-time image acquisition, interpretation and clinical correlation all in one is far more accurate and efficient and leaves no room  for fragmentation of care or ‘separation’  errors in the conclusions  and recommendations. And, there is no waiting!

Our Vision

To provide Comprehensive Women’s Healthcare that is evidence-based,  simple, safe, comfortable, accurate, accessible, useful and affordable.

Our Mission

To reduce the mortality and morbidity of women’s cancers through education, prevention and early detection.

Candidates for Evaluation

Any woman  25 to 90 years of age with a life expectancy of 5 or more years.  Prior mammograms, mammogram issues or abnormalities are NOT required for evaluation or screening.


While there is no question that mammograms are effective in saving lives from breast cancer, they are by no means perfect  in finding all early stage abnormalities. Mammography is quite accurate in smooth and translucent breasts yet are only

50% capable of finding small cancers in women  with dense breasts (85% of the population).  Therefore it is critical that we access additional screening  methodologies to improve the pick-up rate for early, localized cancers.  Currently available and simple strategies  to accomplish this goal are tried and proven.   Note the following:

·         15% of breast cancers are found by the woman  herself if she is performing self breast exams (SBE) monthly with proper technique.

·         A large number of breast cancers are found by ultrasound, not seen on mammography.

Many women are reluctant to have a mammogram for several reasons:

·         Fear of the small amount of radiation exposure.

·         For some…the unpleasant (painful) compression of the breast required to obtain  the image.

·         The concern for releasing abnormal cells into the circulation (unlikely).

·         The occasional request to return for more images.

·         Cost

So, if you are reluctant to have a mammogram at the recommended scheduled  interval, are unsure or inconsistent with performing a SBE consistently, have ‘dense breasts’ as do 85% of the population or would  simply like the additional assurance of healthy  breast status, come to our office for the simplest  and best breast surveillance available…BREAST ULTRASOUND. It is safe, effective, painless and radiation free.  We specialize in and have years of experience with this technology.

BECAUSE KNOWLEDGE  IS A POWERFUL TOOL Women and their  families  often  worry  over the ‘what ifs’, misconceptions and perceived  unknowns of breast and pelvic cancers.   Knowing your individual and families  risk status and being armed  with accurate and useful information plus screening…you will have a tailored prevention and surveillance strategy that  replaces any worry  with full confidence.
