what does a mammogram detect


The doctor reading your mammogram will be looking for different types of breast changes, such as small white spots called calcifications, larger abnormal areas called masses, and other suspicious areas that could be signs of cancer. Mammograms can be used to check for breast cancer in women who have no signs or symptoms of the disease. This type of mammogram 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.

A mammogram A low dose x-ray picture of the breast what is the difference between aspheric and spherical lenses allows a doctor to view glandular tissue and determine the presence of cancer.

The breast is carefully positioned on a film cassette and gently compressed with a special paddle so that the maximum amount of tissue will appear in the image.

This flattening also helps spread the tissue in dense parts of the breast more evenly so that a clearer picture of these areas can be obtained. It also helps doctors determine which changes are noncancerous benign Not harmful; not cancerous referring to a cell or mass. Unlike mzmmogram standard mammography, the digital mammography captures the images electronically and allows them to be viewed on a computer screen.

Women should begin their first mammogram how to fill out a self evaluation for work age 35 first mammogram is a baseline x-ray.

If the results of this screening are normal, then begin yearly mammograms A low dose x-ray picture of the breast that allows a doctor to view glandular tissue and determine the presence of cancer. For all women regardless of age, The Maurer Foundation recommends a monthly breast self-examination and a yearly clinical breast exam ma,mogram a doctor. There has mammoggram much confusion about whether the importance of cancer screenings have been overstated. It is our firm position and that of our founder breast surgeon Dr.

Virginia Maurer that screenings can only give you knowledge and knowledge saves lives. See our official statement. Had these same women waited until age 50, their survival rate would certainly be lower as a result of their more ,ammogram stage of breast cancer.

Until there is a cure for breast cancer, early detection must play a vital role in safe-guarding lives; mammograms are a significant part of a breast cancer early detection strategy. Screening mammograms are the routine basic mammograms that most women receive annually. dles mammograms take longer, are usually performed to receive a proper diagnosis and involve more pictures from different angles mammogran even the magnification of suspicious areas.

Nov 19, †Ј Calcifications: Calcifications are tiny flecks of calcium Ч like grains of salt Ч in the soft tissue of the breast that can sometimes indicate the presence of an early breast cancer. Calcifications usually can't be felt, but they appear on a mammogram. Dec 26, †Ј A mammogram, also known as a digital mammography, is a low dose x-ray which captures a picture of the breast tissue. The breast is carefully positioned on a film cassette and gently compressed with a special paddle so that the maximum amount of tissue will appear in the tiktoklovehere.com: April Zubko. Mammograms are done as part of a regular physical exam to provide a baseline reference or to check any unusual changes in the breast. ItТs the best screening test for lowering the risk of dying.

Mammograms can be used to check for breast cancer in women who have no signs or symptoms of the disease. This type of mammogram 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.

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. 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 before age False-positive results.

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. Overdiagnosis and overtreatment. 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.

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

False-negative results. 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. 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.

Fatty tissue appears dark on a mammogram, whereas fibroglandular tissue appears as white areas. Because fibroglandular tissue and tumors have similar density, tumors can be harder to detect in women with denser breasts. False-negative results occur more often among younger women than among older women because younger women are more likely to have dense breasts.

As a woman ages, her breasts usually become more fatty, and false-negative results become less likely. Some breast cancers grow so quickly that they appear within months of a normal negative screening mammogram.

This situation does not represent a false-negative result, because the negative result of the screening was correct. But it means that a negative result can give a false sense of security.

Some of the cancers missed by screening mammograms can be detected by clinical breast exams physical exams of the breast done by a health care provider.

Even though mammograms can detect malignant tumors that cannot be felt, treating a small tumor does not always mean that the woman will not die from the cancer. A fast-growing or aggressive cancer may have already spread to other parts of the body before it is detected.

Instead, women with such tumors live a longer period of time knowing that they likely have a potentially fatal disease. 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. Radiation exposure.

Mammograms require very small doses of radiation. The risk of harm from this radiation exposure is low, but repeated x-rays have the potential to cause cancer. Although the potential benefits of mammography nearly always outweigh the potential harm from the radiation exposure, women should talk with their health care providers about the need for each x-ray.

In addition, they should always let their health care provider and the x-ray technologist know if there is any possibility that they are pregnant, because radiation can harm a growing fetus.

Many organizations and professional societies, including the United States Preventive Services Task Force which is convened by the Agency for Healthcare Research and Quality, a federal agency , have developed guidelines for mammography screening. 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. Regular high-quality screening mammograms and clinical breast exams are the most sensitive ways to screen for breast cancer.

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. The radiologist who reads the mammogram chooses the category that best describes the level of breast density seen on the mammogram film. The categories, from the least amount of breast density to the highest, are as follows:. Many states in the U. In addition to making mammograms harder to read, dense breasts are a risk factor for breast cancer.

Insurance plans governed by the federal Affordable Care Act must cover screening mammography as a preventive benefit every 1Ч2 years for women age 40 and over without requiring copayments, coinsurance, or deductibles. In addition, many states require that Medicaid and public employee health plans cover screening mammography.

Women should contact their mammography facility or health insurance company for confirmation of the cost and coverage. Medicare pays for annual screening mammograms for all female Medicare beneficiaries who are age 40 or older. Medicare will also pay for one baseline mammogram for female beneficiaries between the ages of 35 and There is no deductible requirement for this benefit. For the hearing impaired, the telephone number is 1ЧЧЧ Women who need a diagnostic mammogram should check with their health insurance provider about coverage.

Some state and local health programs and employers provide mammograms free or at low cost. This program provides screening services, including clinical breast exams and mammograms, to low-income, uninsured women throughout the United States and in several U.

Under the law, all mammography facilities must: 1 be accredited by an FDA-approved accreditation body; 2 be certified by the FDA, or an agency of a state that has been approved by the FDA, as meeting the standards; 3 undergo an annual MQSA inspection; and 4 prominently display the certificate issued by the agency.

Women can ask their doctors or staff at a local mammography facility about FDA certification before making an appointment. Women should look for the MQSA certificate at the mammography facility and check its expiration date. MQSA regulations also require that mammography facilities give patients an easy-to-read report of their mammogram results. Also, a searchable list of these facilities can be found on the FDA website. Women with breast implants should continue to have mammograms.

A woman who had an implant following a mastectomy should ask her doctor whether a mammogram of the reconstructed breast is necessary.

Implants can hide some breast tissue, making it more difficult for the radiologist to detect an abnormality on the mammogram. It is important to let the mammography facility know about breast implants when scheduling a mammogram. The technologist and radiologist must be experienced in performing mammography on women who have breast implants.

If the technologist performing the procedure is aware that a woman has breast implants, steps can be taken to make sure that as much breast tissue as possible can be seen on the mammogram. A special technique called implant displacement views may be used. In the United States, digital mammography has replaced conventional mammography. Digital and conventional mammography both use x-rays to produce an image of the breast; however, in conventional mammography, the image is stored directly on film, whereas, in digital mammography, an electronic image of the breast is stored as a computer file.

This digital information can be enhanced, magnified, or manipulated for further evaluation more easily than information stored on film. Digital images can also be shared electronically, making virtual remote consultations between radiologists and breast surgeons easier. Digital mammography can be done only in facilities that are certified to practice conventional mammography and have received FDA approval to offer digital mammography.

The procedure for having a mammogram with a digital system is the same as with conventional mammography. Three-dimensional 3-D mammography, also known as digital breast tomosynthesis DBT , is a type of digital mammography in which x-ray machines are used to take pictures of thin "slices" of the breast from different angles and computer software is used to reconstruct an image.

This process is similar to how a computed tomography CT scanner produces images of structures inside of the body. Newer tomosynthesis strategies allow DBT to be done alone, potentially reducing the radiation dose to a level closer to that of standard mammography.

Although many women are offered DBT, it has not yet been determined conclusively whether it is superior to 2-D mammography at identifying early cancers and avoiding false-positive results. A large-scale randomized breast screening trial is comparing 3-D mammography with 2-D mammography. NCI is supporting the development of several new technologies to detect breast tumors.

This research ranges from methods being developed in research labs to those that are being studied in clinical trials. Efforts to improve conventional mammography include digital mammography , magnetic resonance imaging MRI , positron emission tomography PET scanning, and diffuse optical tomography, which uses light instead of x-rays to create pictures of the breast.
