1. Mammography

   Mammography (also called mastography) is the process of using low-energy X-rays (usually around 30 kVp) to examine the human breast for diagnosis and screening. The goal of mammography is the early detection of breast cancer, typically through detection of characteristic masses or microcalcifications. As with all X-rays, mammograms use doses of ionizing radiation to create images. These images are then analyzed for abnormal findings. It is usual to employ lower-energy X-rays, typically Mo (K-shell X-ray energies of 17.5 and 19.6 keV) and Rh (20.2 and 22.7 keV) than those used for radiography of bones. Mammography may be 2D or 3D (tomosynthesis), depending on the available equipment and/or purpose of the examination. Ultrasound, ductography, positron emission mammography (PEM), and magnetic resonance imaging (MRI) are adjuncts to mammography. Ultrasound is typically used for further evaluation of masses found on mammography or palpable masses that may or may not be seen on mammograms. Ductograms are still used in some institutions for evaluation of bloody nipple discharge when the mammogram is non-diagnostic. MRI can be useful for the screening of high risk patients, for further evaluation of questionable findings or symptoms, as well as for pre-surgical evaluation of patients with known breast cancer, in order to detect additional lesions that might change the surgical approach (for example, from breast-conserving lumpectomy to mastectomy). For the average woman, the U.S. Preventive Services Task Force recommends (2016) mammography every two years between the ages of 50 and 74, concluding that "the benefit of screening mammography outweighs the harms by at least a moderate amount from age 50 to 74 years and is greatest for women in their 60s". The American College of Radiology and American Cancer Society recommend yearly screening mammography starting at age 40. The Canadian Task Force on Preventive Health Care (2012) and the European Cancer Observatory (2011) recommend mammography every 2 to 3 years between ages 50 and 69. These task force reports point out that in addition to unnecessary surgery and anxiety, the risks of more frequent mammograms include a small but significant increase in breast cancer induced by radiation. Additionally, mammograms should not be performed with increased frequency in patients undergoing breast surgery, including breast enlargement, mastopexy, and breast reduction. The Cochrane Collaboration (2013) concluded after ten years that trials with adequate randomization did not find an effect of mammography screening on total cancer mortality, including breast cancer. The authors of this Cochrane review write: "If we assume that screening reduces breast cancer mortality by 15% and that overdiagnosis and over-treatment is at 30%, it means that for every 2,000 women invited for screening throughout 10 years, one will avoid dying of breast cancer and 10 healthy women, who would not have been diagnosed if there had not been screening, will be treated unnecessarily. Furthermore, more than 200 women will experience important psychological distress including anxiety and uncertainty for years because of false positive findings." The authors conclude that the time has come to re-assess whether universal mammography screening should be recommended for any age group. They state that universal screening may not be reasonable. The Nordic Cochrane Collection updated research in 2012 and stated that advances in diagnosis and treatment make mammography screening less effective today, rendering it "no longer effective". They conclude that "it therefore no longer seems reasonable to attend" for breast cancer screening at any age, and warn of misleading information on the internet. On the contrary, a report in the New England Journal of Medicine attributes the poor effectiveness of national mammography screening programs at reducing breast cancer mortality to radiation-induced cancers.Mammography has a false-negative (missed cancer) rate of at least ten percent. This is partly due to dense tissue obscuring the cancer and the appearance of cancer on mammograms having a large overlap with the appearance of normal tissue. A meta-analysis review of programs in countries with organized screening found a 52% over-diagnosis rate.

1. mammography

   Mammography is a type of medical imaging procedure used to screen and detect early signs of breast cancer or other breast diseases. It uses a low-dose X-ray system to create detailed images of the breast tissue, enabling doctors to identify any abnormalities or changes that may suggest a potential health issue. There are two types of mammograms - screening mammograms for routine check-ups and diagnostic mammograms for investigating suspicious breast changes.

1. Mammography

   Mammography is the process of using low-energy X-rays to examine the human breast and is used as a diagnostic and a screening tool. The goal of mammography is the early detection of breast cancer, typically through detection of characteristic masses and/or microcalcifications. Like all X-rays, mammograms use doses of ionizing radiation to create images. Radiologists then analyze the images for any abnormal findings. It is normal to use lower-energy X-rays than those used for radiography of bones. Ultrasound, ductography, positron emission mammography, and magnetic resonance imaging are adjuncts to mammography. Ultrasound is typically used for further evaluation of masses found on mammography or palpable masses not seen on mammograms. Ductograms are still used in some institutions for evaluation of bloody nipple discharge when the mammogram is non-diagnostic. MRI can be useful for further evaluation of questionable findings as well as for screening pre-surgical evaluation in patients with known breast cancer to detect any additional lesions that might change the surgical approach, for instance from breast-conserving lumpectomy to mastectomy. New procedures, including breast tomosynthesis, may offer benefits in years to come.

Examples of mammography in a Sentence

1. Scott Gottlieb:

   Mammography is the best tool in determining if a woman has breast cancer.

2. Otis Brawley:

   The best studies that we have show that mammography reduces risk of death by 30 %.

3. Otis Brawley:

   We need to also focus on the fact that there are some good screening tests that actually clearly save lives, that we are not using enough, i would point out that 55% to 60% of Americans over the age of 50 are up do date on colorectal cancer screening. We could save a lot of lives if we could just get to 80% by 2018. We could help to decrease the cancer death rate that way. I would point out that there is no debate that mammography saves lives -- and if you look at women over the age of 45, about a third to 40% are not up to date on mammography. Many have never actually even had a mammogram, and we need to work on that.

4. Wendie Berg:

   It seemed like a particularly relevant question because in many countries there is no mammography available, there are now low-tech ultrasound devices that produce images of similar quality to devices used in this study.

5. Tatyana Shamliyan:

   We receive invitations for mammography. It should be the same for urinary incontinence. We would ask, do you have the symptoms? If you do, contact your physician.
