Male Breast Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - General Information About Male Breast Cancer
Incidence and Mortality Estimated new cases and deaths from breast cancer (men only) in the United States in 2011:[ 1 ] New cases: 2,140. Deaths: 450. Male breast cancer is rare.[ 2 ] Less than 1% of all breast carcinomas occur in men.[ 3,4 ] The mean age at diagnosis is between 60 and 70 years,though men of all ages can be affected with the disease. Predisposing risk factors [ 5 ] appear ...
Breast Cancer Treatment and Pregnancy (PDQ®): Treatment - Patient Information [NCI] - General Information about Breast Cancer and Pregnancy
Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast. The breast is made up of lobes and ducts. Each breast has 15 to 20 sections called lobes,which have many smaller sections called lobules. The lobes and lobules are connected by thin tubes called ducts. Anatomy of the breast,showing lymph nodes and lymph vessels. Each breast also contains blood ...
Breast Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Stage IIIB, Inoperable IIIC, IV, Recurrent, and Metastatic Breast Cancer
Inoperable Stage IIIB or IIIC or Inflammatory Breast CancerMultimodality therapy delivered with curative intent is the standard of care for patients with clinical stage IIIB disease. In a retrospective series, approximately 32% of patients with ipsilateral supraclavicular node involvement and no evidence of distant metastases (pN3c) had prolonged disease-free survival (DFS) at 10 years with combined modality therapy. Although these results have not been replicated in another series, this result suggests such patients should be treated with the same intent. Initial surgery is generally limited to biopsy to permit the determination of histology, estrogen-receptor (ER) and progesterone-receptor (PR) levels, and human epidermal growth factor receptor 2 (HER2/neu) overexpression. Initial treatment with anthracycline-based chemotherapy and/or taxane-based therapy is standard.[2,3] In one series of 178 patients with inflammatory breast cancer, DFS

Breast Cancer Screening (PDQ®): Screening - Health Professional Information [NCI] - Overview
Note: Separate PDQ summaries on Breast Cancer Prevention, Breast Cancer Treatment, Male Breast Cancer Treatment, and Breast Cancer Treatment and Pregnancy are also available.This summary covers the topic of breast cancer screening and includes information about breast cancer incidence and mortality, risk factors for breast cancer, the process of breast cancer diagnosis, and the benefits and harms of various breast cancer screening modalities. This summary also includes information about screening among special populations.Mammography is the most widely used screening modality, with solid evidence of benefit for women aged 40 to 74 years. Clinical breast examination and breast self-exam have also been evaluated but are of uncertain benefit. Technologies such as ultrasound, magnetic resonance imaging, tomosynthesis, and molecular breast imaging are being evaluated, usually as adjuncts to mammography.Screening With MammographyBenefitsBased on solid evidence, screening mammography may

Breast Cancer Screening (PDQ®): Screening - Health Professional Information [NCI] - Breast Cancer Screening Concepts
BiasNumerous uncontrolled trials and retrospective series have documented the ability of mammography to diagnose small, early-stage breast cancers, which have a favorable clinical course. Although several trials also show better cancer-related survival in screened versus nonscreened women, a number of important biases may explain that finding:Lead-time bias: Survival time for a cancer found mammographically includes the time between detection and the time when the cancer would have been detected because of clinical symptoms, but this time is not included in the survival time of cancers found because of symptoms.Length bias: Mammography detects a cancer while it is preclinical, and preclinical durations vary. Cancers with longer preclinical durations are, by definition, present during more opportunities for discovery and therefore are more likely to be detected by screening; these cancers tend to be slow growing and to have better prognoses, irrespective of screening.Overdiagnosis
