In cancer screening, a negative result means no abnormality is present. False-negative results occur when mammograms appear normal even though breast cancer is present. Overall, screening mammograms miss about 20 of breast cancers that are present at the time of screening. False-negative results can lead to delays in treatment and a false sense of security for affected women. One cause of false-negative results is high breast density. Breasts contain both dense tissue (i.e., glandular tissue and connective tissue, together known as fibroglandular tissue) and fatty tissue.
Digital breast tomosynthesis will replace mammography
False-positive results occur when radiologists see write an abnormality (that is, a potential positive) on a mammogram but no cancer is actually present. All abnormal mammograms should be followed up with additional testing (diagnostic mammograms, ultrasound, and/or biopsy ) 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. False-positive results are more common for younger women, women with dense breasts, women who have had previous breast biopsies, women with a family history of breast cancer, and women who are taking estrogen (for example, menopausal hormone therapy ). The chance of having a false-positive result increases with the number of mammograms a woman has. More than 50 of women screened annually for 10 years in the United States will experience a false-positive result, and many of these women will have a biopsy. Screening mammograms can find cancers and cases of ductal carcinoma in situ (dcis, a noninvasive tumor in which abnormal cells that may become cancerous build up in the lining of breast ducts) that need to be treated. However, they can also find cases of dcis and small cancers that would never cause symptoms or threaten a womans life. This phenomenon is called "overdiagnosis." Treatment of overdiagnosed manager cancers and overdiagnosed cases of dcis is not needed and results in "overtreatment.". Because doctors cannot easily distinguish cancers and cases of dcis that need to be treated from those that do not, they are all treated.
How are screening and diagnostic mammograms different? The same machines are used for both types of mammograms. However, diagnostic mammography takes longer to perform than screening mammography and the total dose of radiation is higher because more x-ray images are needed to obtain views of the breast from several angles. The technologist may magnify a suspicious area to produce a detailed picture that can help the doctor make an accurate diagnosis. What are the benefits and potential harms of screening mammograms? 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. Results from randomized clinical trials and other studies show that screening mammography can help reduce the number of deaths from breast cancer among women ages 40 to 74, especially for those over age 50 ( 1 ). However, studies to date have not shown a benefit from regular screening mammography in women under age 40 or from baseline screening mammograms (mammograms used for comparison) taken best before age. The benefits of screening mammography need to be balanced against its harms, which include: False-positive results.
Mammograms can be used to check for breast cancer in women who have no signs or symptoms of the disease. This type of mammogram reviews is called a screening mammogram. Screening mammograms usually involve two or more x-ray pictures, or images, of each breast. The x-ray images often make it possible to detect tumors that cannot be felt. Screening mammograms can also find microcalcifications (tiny deposits of calcium ) that sometimes indicate the presence of breast cancer. Mammograms can also be used to check for breast cancer after a lump or other sign or symptom of the disease has been found. This type of mammogram is called a diagnostic mammogram. Besides a lump, signs of breast cancer can include breast pain, thickening of the skin of the breast, nipple discharge, or a change in breast size or shape; however, these signs may also be signs of benign conditions. A diagnostic mammogram can also be used to evaluate changes found during a screening mammogram or to view breast tissue when it is difficult to obtain a screening mammogram because of special circumstances, such as the presence of breast implants.

What is Breast Tomosynthesis? Tomosynthesis is a revolutionary technology that gives radiologists the ability to identify and characterize individual breast structures without the confusion of essay overlapping tissue. During a tomosynthesis scan, multiple images of the breast are taken at various angles. These images produce a three dimensional reconstruction of the breast that the radiologist can scroll through in one-millimeter thick slices. Reviewing breast tissue slice by slice removes the confusion of superimposed tissue found in traditional two dimensional mammography, allowing for more accurate diagnosis. There are risks and benefits to each technology and a womans personal screening plan should always be developed in partnership with her healthcare provider.

Journal of the American Medical Association (June 2014) showed a positive benefit to the use of tomosynthesis in detecting cancers and excluding false positives. The effect on outcomes is yet to be determined, but as a diagnostic tool it cannot be underestimated since in provides a more holistic view of the breast and can even provide imaging on thicker tissues or be more effective in the case where implants. Notes and Special Information, special responsibilities note: over the past couple of years advances in imagery, big data, and cloud storage have made it possible to bring more advances and medical knowledge to the forefront in this field. Machine vision and computer algorithms also help identify suspect structures and eliminate many artifacts and false positives that had led to anxiety in the past. See your doctor for availability. Also, ask how effective it would be for your body type since in some cases 3d mammography has the same effectiveness as standard mammograms, which are cheaper and covered by insurance. Also note the warning that tomosynthesis has twice the raditation as a traditional mammogram, and radiation can cause cancer by itself. Copyright 2016 by Informational Sites Collective.

examine in a virtual environment, so suspected tumors and masses in the breast can be detected with a higher degree of accuracy. Compared to two dimensional mammograms, 3D mammography through tomosynthesis offers less radiation exposure, and the digital nature of the process allows imaging to be sent to specialists worldwide. . There are also advantages to the patient, since the procedure allows for less painful methods of "locking down" the breast for the scan, and in some women breast tissue is denser, which makes traditional mammograms harder to read. Technically, tomosynthesis utilizes a digital imaging algorithm to re-create x-ray data in a three dimensional way. Hologic, general Electric, and siemens are all developing tomosynthesis-based breast imaging equipment. There is also a growing interest in the new devices, since they promise a more comfortable experience for the patient and more accurate mammography for medical professionals. Machines are reported to cost upwards of three hundred thousand dollars each, but in many cases doctors are already seeing a high volume of inquiries. A recent study published in the.
