The value of screening mammograms was questioned in November when the U. Preventive Services Task Force recommended that routine screening mammograms for women with an average risk of breast cancer should start at age 50 instead of age The recommended changes were very controversial and were not universally adopted. Since that time, the American Medical Association, the American Congress of Obstetricians and Gynecologists, the American College of Radiology, the American Cancer Society, the National Cancer Institute, and the National Comprehensive Cancer Network all have issued guidelines saying that all women should be eligible for screening mammograms starting at age Finding breast cancers early with mammography has also meant that many more women being treated for breast cancer are able to keep their breasts.

Screening mammography is a specific type of breast imaging that uses low-dose x-rays to detect cancer early — before women experience symptoms — when it is most treatable.
- Your technologist will ask you to stand facing the mammography machine, and then place one breast at a time on a flat surface.
- A mammogram is an X-ray picture of the breast.
- A mammogram is an x-ray picture of the breast.
There are two techniques for creating a mammogram. Film-screen mammography creates a photographic film, while digital mammography creates digital images. Both methods use the same procedure for taking the image.
The person having the mammogram will place their breast between two clear plates, which will squeeze it between them to hold it in place. This flattens the breast for a better image and stops the image from blurring. The machine takes a picture of the breast from two angles. A specialist then checks the mammogram for anything unusual that could be a sign of cancer. The image of the breast is known as a mammogram. The background of the image will be black, and the breast will show up in grays and whites.
Some people have more dense tissue in their breasts. This can make it harder to detect abnormalities on a mammogram as a tumor is made up of dense tissue and will also appear white. The breasts tend to become less dense with age. Less dense tissue, such as fat, shows up gray on a mammogram. A standard mammogram will usually be mostly gray, with some white areas showing healthy dense tissue.
More white on the image does not always indicate a health problem. Everyone's breasts are different, so no two mammogram images will be the same. Healthy mammograms can still vary in appearance. A medical professional who checks imaging tests, such as X-rays or MRI scans , is called a radiologist.
They will look carefully at the mammogram to interpret the results. Expert, evidence-based advice delivered straight to your inbox to help you take control of your health.
Any area that does not look like normal tissue is a possible cause for concern. The radiologist will look for areas of white, high-density tissue and note its size, shape, and edges. A lump or tumor will show up as a focused white area on a mammogram.
Tumors can be cancerous or benign. If a tumor is benign, it is not a health risk and is unlikely to grow or change shape. Most tumors found in the breasts are non-cancerous. Small white specks are usually harmless. The radiologist will check their shape and pattern, as they can sometimes be a sign of cancer. As well as dense breast tissue and possible tumors, a radiologist will look for anything unusual on a mammogram.
A mammogram can also give a person information about their breast density. People with dense breasts have a slightly higher risk of breast cancer. Dense breasts can make it more difficult to find abnormalities on a mammogram.
Mammograms are still possible if a person has had breast cancer surgery or implants. However, it may be necessary to take more images of each breast, and it might take longer to check the images. A radiologist will often compare a mammogram against previous images. This can help them to spot any changes and decide whether an unusual area could be a sign of cancer. By being aware of how their breasts usually look and feel, they are more likely to notice any changes.
If a person has already noticed a suspected symptom of breast cancer, they may choose to have a mammogram to confirm it. This is called a diagnostic mammogram. Guidelines from the American College of Physicians recommend talking to a doctor about regular screening from the age of 40 years. The guidelines recommend that women with an average risk of breast cancer attend routine screening as follows:. The American Cancer Society have a different set of recommendations.
The most important thing is for a person to ask their doctor for the best course of action for them. This is to make sure that doctors across the United States are using the same terms.
A medical professional should explain the results clearly. They may recommend further tests to check anything that looks suspicious. It is common to need further tests after a mammogram, as doctors will want to look more closely at any abnormalities on the images. A call-back does not necessarily mean that cancer is present. Mammograms are currently the best method available for detecting breast cancer or checking to see how breast cancer is responding to treatment. However, mammograms are not perfect, and it can be difficult to see any abnormalities in people with dense breasts.
A mammogram will look different for every individual, and there is no standard normal or abnormal image. Areas that appear white on a mammogram may need follow-up tests but are not often the result of breast cancer.

Do Mammograms Save Lives - Mammography Debate | Susan G. Komen®
Mammography is a screening test for breast cancer. It's used to find breast cancer early before it causes any warning signs or symptoms , when the chances of survival are highest. Regular mammography along with follow-up tests and treatment if diagnosed can reduce the chance of dying from breast cancer.
However, the risks and benefits are not the same for all women. The benefits of screening mammography vary by age. Women ages get the most overall benefit for a number of reasons [ 23 ]. For example, breast cancer in women younger than 50 is much less common than breast cancer in women 50 and older [ 47 ].
Risk of dying from breast cancer for women who got mammograms on a regular basis compared to women who did not. Number of breast cancer deaths avoided per 10, women screened for 10 years.
Adapted from U. Preventive Services Task Force, [ 23 ]. Although the benefits of mammography are real, a woman who gets regular mammograms may still be diagnosed with breast cancer and unfortunately, may still die from the disease.
Over-diagnosis occurs when a mammogram finds ductal carcinoma in situ DCIS or small, invasive breast cancers that would have never caused symptoms or problems if left untreated. These breast cancers may never grow and some may even shrink on their own. Or, a person may die from another cause before breast cancer becomes a problem.
Studies suggest percent of DCIS and small, invasive breast cancers found with mammography may be over-diagnosed [ , ]. A meta-analysis of 3 randomized controlled trials found over-diagnosis from mammography was 19 percent [ 51 ]. Even without treatment, these over-diagnosed breast cancers would never progress to invasive breast cancer and would never cause problems in a woman's lifetime.
Over-treatment occurs when a cancer that would have never caused symptoms or problems if left untreated is found over-diagnosis and treated. Even without treatment, the breast cancer would never have caused a problem. Over-treatment is a concern for those with ductal carcinoma in situ DCIS and some very early invasive cancers.
Although DCIS is non-invasive, without treatment, the abnormal cells can progress to invasive breast cancer over time. Left untreated, findings from older studies before mammography was used estimate percent of DCIS cases may progress to invasive breast cancer [ 52 ].
Since the introduction of mammography in the s, the number of women diagnosed with DCIS has greatly increased. For now, women with DCIS or a small, invasive breast cancer are treated with a lumpectomy plus radiation therapy or a mastectomy. With either surgery, hormone therapy may also be needed. Some women with small, invasive breast cancer may also get chemotherapy.
Since not all cases of DCIS and small, invasive breast cancer will progress, some women may be over-treated. Researchers are studying ways to identify which cases of DCIS and small, invasive breast cancer are most likely to progress.
Researchers are also studying whether some cases with lower risk profiles can be treated less aggressively than they are treated now. Learn more about DCIS. Sometimes a mammogram shows something abnormal that might be cancer, but turns out not to be cancer. This is called a false positive result. If your mammogram shows something abnormal, you will need follow-up tests to check whether or not the finding is breast cancer.
These tests may include a follow-up mammogram diagnostic mammogram , breast ultrasound or breast MRI. Sometimes, a biopsy is needed.
A biopsy removes a small amount of tissue in the breast to check for cancer. If you have an abnormal finding on a mammogram, try not to panic or worry. Among older women, there are fewer false positive results [ 23 ]. Risks of screening mammography per 10, women estimates for a single screening.
The benefits and risks of mammography for the population can differ from those for an individual woman. At the population level, we can say mammography saves lives by lowering the risk of dying from breast cancer. However, it doesn't save the life of every woman who gets screened. Not all women get the same benefit from mammography. For example, say a large group of women get regular mammograms. Some of the women in the group will have a breast cancer that's found early.
They will get treatment and will not die from breast cancer. However, for an individual woman who never develops breast cancer there may be no benefit from regular mammogram screening, only risks.
For any one woman, this biopsy may not be a big problem as the results were negative for breast cancer. In making screening guidelines, organizations look at the benefits and risks for a population of women rather than the benefits and risks for any one woman. They try to give recommendations that give the most benefit with the least amount of risk to the population.
These benefits and risks may be different for an individual woman though. Some women will get more benefits than the population as a whole and some will get more risks. While any health decision is a personal one that involves weighing benefits and risks, most health organizations recommend women get mammograms on a regular basis.
Figure 3. Learn about breast cancer screening recommendations for women at higher than average risk. Mammography in women ages may save lives, but the benefit is less than for older women. Individual study findings vary [ 8,23 ]. Some health organizations have concluded the modest potential benefits of mammography for women in their 40s outweigh the risks of false positive results , over-diagnosis and over-treatment [ ].
Learn more about breast cancer screening recommendations for women ages Health organizations agree women ages and at least some women 70 and older should get mammograms. Some health organizations recommend mammography every year for women and for women 70 and older who are in good health [ 4 ].
Other organizations recommend mammography every other year every 2 years [ ]. For example, the U. Preventive Services Task Force recommends mammography every 2 years starting at age 50 [ 2 ].
And, the American Cancer Society recommends mammography every 2 years starting at age 55 [ 3 ]. The Task Force reviewed the scientific evidence and concluded mammography every 2 years gives almost as much benefit as mammography every year while reducing risks [ 2 ].

Over-diagnosis and over-treatment Over-diagnosis and over-treatment are the main risks of mammography screening. Over-diagnosis Over-diagnosis occurs when a mammogram finds ductal carcinoma in situ DCIS or small, invasive breast cancers that would have never caused symptoms or problems if left untreated. Over-treatment Over-treatment occurs when a cancer that would have never caused symptoms or problems if left untreated is found over-diagnosis and treated. In the same way, small, invasive breast cancers may grow over time.
