Breast Cancer Screening (PDQ®): Screening - Health Professional Information [NCI] - Mammography—Variables Associated with Accuracy
Patient CharacteristicsSeveral characteristics of women being screened that are associated with the accuracy of mammography include age, breast density, whether it is the first or subsequent exam, and time since last mammogram. Younger women have lower sensitivity and higher false-positive rates on screening mammography than do older women (refer to the Breast Cancer Surveillance Consortium performance measures by age for more information).For women of all ages, high breast density is associated with 10% to 29% lower sensitivity. High breast density is an inherent trait, which can be familial [2,3] but also may be affected by age, endogenous  and exogenous [5,6] hormones, selective estrogen receptor modulators such as tamoxifen, and diet. Hormone therapy is associated with increased breast density and is associated not only with lower sensitivity but also with an increased rate of interval cancers.The Million Women Study in the United Kingdom revealed

Breast Cancer, Metastatic or Recurrent - Other Considerations for Pregnancy and Breast Cancer
LactationSuppression of lactation does not improve prognosis. If surgery is planned, however, lactation should be suppressed to decrease the size and vascularity of the breasts. If chemotherapy is to be given, lactation should also be suppressed because many antineoplastics (i.e., cyclophosphamide and methotrexate), when given systemically, may occur in high levels in breast milk and would affect the nursing baby. In general, women receiving chemotherapy should not breastfeed.Fetal Consequences of Maternal Breast CancerNo damaging effects on the fetus from maternal breast cancer have been demonstrated, and there are no reported cases of maternal-fetal transfer of breast cancer cells. Consequences of Pregnancy in Patients with a History of Breast CancerBased on limited retrospective data, pregnancy does not appear to compromise the survival of women with a previous history of breast cancer, and no deleterious effects have been demonstrated in the fetus.[1,2,3,4,5,6,7,8,9] Some

Genetics of Breast and Ovarian Cancer (PDQ®): Genetics - Health Professional Information [NCI] - About This PDQ Summary
Purpose of This SummaryThis PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about the genetics of breast and ovarian cancer. It is intended as a resource to inform and assist clinicians who care for cancer patients. It does not provide formal guidelines or recommendations for making health care decisions.Reviewers and UpdatesThis summary is reviewed regularly and updated as necessary by the PDQ Cancer Genetics Editorial Board, which is editorially independent of the National Cancer Institute (NCI). The summary reflects an independent review of the literature and does not represent a policy statement of NCI or the National Institutes of Health (NIH). Board members review recently published articles each month to determine whether an article should:be discussed at a meeting,be cited with text, orreplace or update an existing article that is already cited.Changes to the summaries are made through a consensus
Genetics of Breast and Ovarian Cancer (PDQ®): Genetics - Health Professional Information [NCI] - Psychosocial Issues in Inherited Breast and Ovarian Cancer Syndromes
IntroductionPsychosocial research in the context of cancer genetic testing helps to define psychological outcomes, interpersonal and familial effects, and cultural and community responses. It also identifies behavioral factors that encourage or impede screening and other health behaviors. It can enhance decision-making about risk-reduction interventions, evaluate psychosocial interventions to reduce distress and/or other negative sequelae related to risk notification and genetic testing, provide data to help resolve ethical concerns, and predict the interest in testing of various groups. Research in these areas is limited by few randomized controlled trials, and many reports are based on uncontrolled studies of selected high-risk populations. Research is likely to expand considerably with access to larger populations of at-risk individuals. There have been a number of descriptions of cancer
