Where Can I Find Current Recommendations For Screening Mammography

Dr. April Spencer – Mammogram: BI-RADS 3

Many organizations and professional societies, including the United States Preventive Services Task Force , have developed guidelines for mammography screening, as summarized by the Centers for Disease Control and Prevention . All recommend that women talk with their doctor about the benefits and harms of mammography, when to start screening, and how often to be screened.

Although NCI does not issue guidelines for cancer screening, it conducts and facilitates basic, clinical, and translational research that informs standard clinical practice and medical decision making that other organizations may use to develop guidelines.

What Are The Signs And Symptoms Of Breast Cancer

Knowing the signs and symptoms of breast cancer may help save your life. When the disease is discovered early, there are more treatment options and a better chance for a cure.

Most painful breast lumps are not cancerous. Any discrete breast lump whether painful or not should be evaluated because breast cancer often presents as a lump or thickening.

Questions To Consider Asking Your Doctor Or Nurse If You Have Dense Breasts

Ask these questions to get information thats specific to you, based on your personal medical history:

  • What are the dense breast-related findings in my recent mammogram?
  • Do you recommend additional screening or diagnostic tests for me?
  • What is my overall personal risk of breast cancer, given my risk and protective factors?

Category : Biopsy Required

Were recommending a biopsy, and your chance of the finding being breast cancer is greater than 2% and less than 95%, says Dr. Reig. Yes, thats a mighty wide range. And because of that, this category can be further broken down into three risk levels:

  • 4a) Your cancer risk is greater than 2% but less than or equal to 10%.

  • 4b) Your cancer risk is greater than 10% and less than or equal to 50%.

  • 4c) The risk is greater than 50% and less than 95%.

A study in the Journal of Roentgenology found that comparing tests and BI-RADS values was helpful in classifying risk levels of suspicious calcifications.

Are Dense Breasts A Risk Factor For Breast Cancer

Digital breast tomosynthesis and breast ultrasound: Additional roles in ...

Dense breasts are not considered an abnormal breast condition or a disease. However, dense breasts are a risk factor for breast cancer. That is, women with dense breasts have a higher risk of breast cancer than women with fatty breasts. This risk is separate from the effect of dense breasts on the ability to read a mammogram.

In most states, mammography providers are required to inform women if they have dense breasts. A United States map showing information about specific state legislation is available from DenseBreast-info.org.

Dense Breasts And Other Breast Cancer Risk Factors

Breast cancer is one of the most frequently diagnosed cancers among women. The majority of women diagnosed with breast cancer have no known family history or other risk factors. Only 5-10 percent of breast cancers are due to a genetic cause. Thats why screening for breast cancer is so important. The most significant risk factors for breast cancer includes being female and age. However, increased breast density is a strong independent risk factor for developing breast cancer. The reason it is so important for women to be aware of their breast density is that there are other approaches, in addition to mammography, which can help detect breast cancers which would not be seen with mammography alone such as Automated Breast Ultrasound , Breast Specific Gamma Imaging and Magnetic Resonance Imaging .

Does Having Dense Breast Tissue Affect A Mammogram

Dense breasts can make a mammogram more difficult to interpret. That’s because dense breast tissue and some abnormal breast changes, such as calcifications and tumors, both appear as white areas in the mammogram, whereas fatty tissue appears as dark areas.

As a result, mammography is less sensitive in women with dense breaststhat is, it is more likely to miss cancer. Women with dense breasts may be called back for follow-up testing more often than women with fatty breasts.

Primary Exposure Of Interest

Our primary exposure of interest was FHBC. We defined FHBC as participants with a first-degree relative with a history of breast cancer. Therefore, FHBC was categorized into a dichotomous variable of yes and no. We further stratified this variable among women with FHBC in mothers or sisters alone. Lastly, we analyzed the total number of affected relatives with an FHBC: 0=participants with zero first-degree relatives with a history of breast cancer 1=one mother or sister with breast cancer, 2=mother and at least one sister with a history of breast cancer.

Main Outcomes And Measures

My First Week of Chemotherapy (breast cancer)

The primary outcomes were mammographic breast density measured quantitatively as volumetric percent density using Volpara and qualitatively using BI-RADS breast density . Multivariable regressions were performed using a log-transformed normal distribution for the discovery set and a logistic distribution for the validation set.

The Reports Of Your Radiology Exams Usually Contain Three Sections:

  • Exam description and history the type of exam, day it was performed, the reason it was performed and any important patient information
  • Findings a detailed description of the important findings on the exam including size, shape, location and changes
  • Impression a summary of the findings, what they mean and what to do about them Radiologists use standard terms in reports to describe the appearance of important findings.

Some examples of those terms include mass, architectural distortion and calcifications. The radiologist will also describe the size, shape and location of important findings. The size and location can be critical to making decisions about the kind of operation and other treatments you might have.

Radiologists will use a clock face or quadrant to describe the location. There is a separate clock for each breast and they are oriented as if the doctor is looking at you during an examination. In the diagram below, the nipple is in the center of the clock for both breasts. The outer left breast is at 3 oclock and the outer right breast is at 9 oclock. In the left breast the upper outer quadrant is between 12 and 3 oclock.

The radiologist will also describe the size and location of a finding by indicating the distance from the nipple in centimeters. Centimeters are smaller than an inch. There are 2.54 centimeters in an inch.

What Are Researchers Studying About The Relationship Between Breast Density And Breast Cancer

Can Breast Cancer Be Diagnosed With Ultrasound
  • Can imaging tests such as 3-D mammography, MRI, ultrasound, or other imaging procedures help provide a clearer picture of breast density?
  • Are there certain patterns or areas of dense breast tissue that are particularly risky?
  • Why do some women with dense breasts develop breast cancer, whereas others do not?
  • What biologic mechanisms explain the association between high breast density and increased breast cancer risk?
  • Can biomarkers be identified that may help predict whether breast cancer will develop in a woman with dense breasts?
  • Are changes in breast density over time associated with changes in breast cancer risk?
  • Can women reduce their breast density, and potentially their risk of developing or dying from breast cancer, by taking medicines or by applying topical agents on their breasts?

NCI’s Division of Cancer Prevention supports research on cancer screening and risk factors, including breast density, such as this clinical trial for women with dense breasts.

NCIs Division of Cancer Control and Population Sciences supports research such as the Cancer Intervention and Surveillance Modeling Network Breast Working Group. CISNET is a consortium of NCI-sponsored investigators conducting simulation modeling to improve our understanding of the impact of prevention, screening, and treatment on population trends in incidence and mortality.

Validation And Calibration Of The Nomogram

In the primary dataset, Harrellâs C-index produced by the prediction model was 0.813 for the established nomogram. In the validation set, the nomogramâs C-index for the prediction of malignant lesions was 0.765 . The calibration plots presented excellent agreement in the training cohort and good agreement in the validation cohort between the nomogram prediction and the real observation made for the histological findings .

Analysis Of Histological Findings In The Training Set

In the training set, risk factors were determined by univariate analysis with the Ï2 test or Fisherâs exact test for different demographic and imaging features. These variables comprised age, family history of breast cancer, history of benign breast biopsy, clinical examination of the mammary gland, US imaging features , and MG imaging features . Among the malignant patients, the rate of family history of breast cancer was much higher than that of benign patients . In the malignant patients, the lesion margin was predominantly not circumscribed , the shapes of lesions were significantly more irregular , and the orientation was significantly nonparallel . Moreover, the rate of low suspicious lymph nodes was higher in malignant patients . Nine lesions in the 42 malignant patients were found to be suspicious for MG calcifications, while in benign patients, the rate was 2.1% .

What Are The Benefits And Potential Harms Of Screening Mammograms

How To Catch Breast Cancer Early: Stanford Doctors Explain Mammography Options

Early detection of breast cancer with screening mammography means that treatment can be started earlier in the course of the disease, possibly before it has spread. Randomized clinical trials and other studies show that screening mammography can help reduce deaths from breast cancer among women ages 40 to 74 years at average risk of breast cancer, with the evidence of benefit being strongest for women ages 50 to 69 years . However, no studies to date have shown a benefit from regular screening mammography in women under age 40 or from baseline screening mammograms taken before age 40.

The benefits of screening mammography need to be balanced against its harms, which include:

False-positive results. False-positive results occur when radiologists see an abnormality on a mammogram but no cancer is actually present. All abnormal mammograms should be followed up with additional testing to determine whether cancer is present.

False-positive mammogram results can lead to anxiety and other forms of psychological distress in affected women. The additional testing required to rule out cancer can also be costly and time consuming and can cause physical discomfort.

Because doctors cannot easily distinguish cancers and cases of DCIS that need to be treated from those that do not, they are all treated.

In addition, finding breast cancer early may not help prolong the life of a woman who is suffering from other, more life-threatening health conditions.

What Is The Best Method Of Screening For Breast Cancer

Regular high-quality screening mammograms and clinical breast exams are the most sensitive ways to screen for breast cancer.

Regular breast self-exam, or BSEthat is, checking ones own breasts for lumps or other unusual changesis not specifically recommended for breast cancer screening. In clinical trials, BSE alone was not found to help reduce the number of deaths from breast cancer.

However, many women choose to examine their own breasts. Women who do so should remember that breast changes can occur because of pregnancy, aging, or menopause during menstrual cycles or when taking birth control pills or other hormones. It is normal for breasts to feel a little lumpy and uneven. Also, it is common for breasts to be swollen and tender right before or during a menstrual period. Whenever a woman notices any unusual changes in her breasts, she should contact her health care provider.

How Is Breast Density Categorized In A Mammogram Report

Doctors use the Breast Imaging Reporting and Data System to classify breast density. This system, developed by the American College of Radiology, helps doctors interpret and report back mammogram findings. Doctors who review mammograms are called radiologists. BI-RADS classifies breast density into four categories:

If your mammogram report letter says you have dense breasts, it means that you have either heterogeneously dense breast tissue or extremely dense breast tissue.

The four breast density categories are shown in this image. Breasts can be almost entirely fatty , have scattered areas of dense fibroglandular breast tissue , have many areas of glandular and connective tissue , or be extremely dense . Breasts are classified as dense if they fall in the heterogeneously dense or extremely dense categories.

Other Potential Signs Of Breast Cancer Include:

  • Lump in the breast or in the underarm
  • A spontaneous or bloody discharge from the nipple
  • New retraction or indentation of the nipple
  • A change in the size or contour of the breast
  • Any flattening or indentation of the skin over the breast
  • Redness or pitting of the skin over the breast, like the skin of an orange
  • Crustiness, ulceration or rash of the nipple or areola

A number of conditions other than breast cancer can cause breasts to change in size or feel. Breast tissue changes naturally during pregnancy and a womans menstrual cycle. Other possible causes of non-cancerous breast changes include fibrocystic changes, cysts, fibroadenomas, infection or injury.

If you find a lump or other change in your breast even if a recent mammogram was normal you should call us immediately. If you havent yet gone through menopause, you may want to wait through one menstrual cycle before seeing your doctor. If the change hasnt gone away after a month, have it evaluated.

What Is Breast Density And How Does It Impact My Risk For Cancer

Ductal Carcinoma in Situ of the Breasts: Review of MR Imaging Features ...

Breast Density is a measure of the amount of breast tissue a woman has. The more tissue, the greater the density and the higher the risk of breast cancer. However, in women with dense breast tissue, mammograms are not as effective in detecting the cancer. This is because both breast tissue and breast cancer will appear white on a mammogram and the lack of contrast makes identification of the cancer more difficult.

Digital mammography is the standard to detect early curable breast cancer. Mammography is effective and is probably the most important reason that smaller more curable breast cancers are being detected and that the death rate from breast cancer is decreasing. However, the ability of mammography to detect breast cancer in women with dense breast tissue is limited.

The issue of breast density is important. Nearly half of all women in the United States have dense breast tissue. Women with dense breasts are at a 4-6 times higher risk of developing breast cancer than women who do not.

Although breast density is loosely associated with age, with nearly three-fourths of women in their 30s having dense breast tissue, more than a quarter of women in their 70s also have dense breast tissue.

Family History Of Breast Cancer Breast Density May Be Linked

This study investigated the relationships seen among premenopausal women with a family history of breast cancer and their breast tissue density as seen at their annual mammographic screening.

A potential link has been found among premenopausal women between their mammography-determined breast cancer and having a family history of the disease, with the investigators of a new study in JAMA Network Open ultimately stressing the importance of initiating annual screening mammograms at an earlier age in this patient population.

Family history of breast cancer and mammographic breast density are independent risk factors for breast cancer, but the association of FHBC and mammographic breast density in premenopausal women is not well understood, they wrote. Our primary outcomes were mammographic breast density measured quantitatively as volumetric percent density using Volpara and qualitatively using BI-RADS breast density .

The 14,415 women in the study consisted of a discovery cohort whose data were collected between December 2015 and October 2016 and a validation cohort whose data were collected between June 2010 and December 2015. All data were analyzed from June 2018 through June 2020. Mean ages were similar among these cohorts and between those with and without a FHBC: 47.1 and 47.7 years, respectively, in the discovery set and discovery set and 46.8 and 47.5 years in the validation cohort. A majority of participants were non-Hispanic White .
