Mammogram

Also called: Breast Cancer Screening - Mammography, Screening Mammography, Diagnostic Mammography

A mammogram is a low-dose x-ray picture of the breast. A mammogram is used to look for early signs of breast cancer. Regular mammograms are the best tests doctors have to find breast cancer early, sometimes up to three years before it can be felt.

- Screening mammograms are done for women who have no symptoms of breast cancer. It usually involves two x-rays of each breast. Screening mammograms can detect lumps or tumors that cannot be felt. They can also find microcalcifications or tiny deposits of calcium in the breast, which sometimes mean that breast cancer is present.
- Diagnostic mammograms are used to check for breast cancer after a lump or other symptom or sign of breast cancer has been found. Signs of breast cancer may include pain, thickened skin on the breast, nipple discharge, or a change in breast size or shape. This type of mammogram also can be used to find out more about breast changes found on a screening mammogram, or to view breast tissue that is hard to see on a screening mammogram. A diagnostic mammogram takes longer than a screening mammogram because it involves more x-rays in order to obtain views of the breast from several angles. The technician can magnify a problem area to make a more detailed picture, which helps the doctor make a correct diagnosis.
A digital mammogram also uses x-rays to produce an image of the breast, but instead of storing the image directly on film, the image is stored directly on a computer. This allows the recorded image to be magnified for the doctor to take a closer look. Current research has not shown that digital images are better at showing cancer than x-ray film images in general. But, women with dense breasts who are pre- or perimenopausal, or who are younger than age 50, may benefit from having a digital rather than a film mammogram. Digital mammography may offer these benefits:
- Long-distance consultations with other doctors may be easier because the images can be shared by computer.
- Slight differences between normal and abnormal tissues may be more easily noted.
- The number of follow-up tests needed may be fewer.
- Fewer repeat images may be needed, reducing exposure to radiation.
A mammogram is a low-dose x-ray exam of the breasts to look for changes that are not normal. A mammogram allows the doctor to have a closer look for changes in breast tissue that cannot be felt during a breast exam. Women ages 50 to 74 years should get a mammogram every 2 years. Women younger than age 50 should talk to a doctor about when to start and how often to have a mammogram.
Mammograms can not find all problems. So, every woman should work with her doctor to check her breasts. Call your doctor or clinic if you notice any change in your breasts like:
- a lump
- thickening
- liquid leaking from the nipple or changes in how the nipple looks
First, check with the place you are having the mammogram for any special instructions you may need to follow before you go. Here are some general guidelines to follow:
- If you are still having menstrual periods, try to avoid making your mammogram appointment during the week before your period. Your breasts will be less tender and swollen. The mammogram will hurt less and the picture will be better.
- If you have breast implants, be sure to tell your mammography facility that you have them when you make your appointment.
- Wear a shirt with shorts, pants, or a skirt. This way, you can undress from the waist up and leave your shorts, pants, or skirt on when you get your mammogram.
- Don't wear any deodorant, perfume, lotion, or powder under your arms or on your breasts on the day of your mammogram appointment. These things can make shadows show up on your mammogram.
- If you have had mammograms at another facility, have those x-ray films sent to the new facility so that they can be compared to the new films.
- Tell the clinic if you have physical disabilities that may make it hard for you to sit up, lift your arms, or hold your breath.
- Talk with the staff about how they will handle issues of modesty that you may have due to your religion.

Breast tissue that shows no signs of a mass or calcifications is considered normal. Most abnormal findings on a screening mammogram turn out to be benign (not cancer) or nothing to worry about. New findings or changes must be further evaluated.

What can mammograms show?

The radiologist will look at your x-rays for breast changes that do not look normal and for differences in each breast. He or she will compare your past mammograms with your most recent one to check for changes. The doctor will also look for lumps and calcifications.

Possible mammogram findings include:

Lumps (mass or tumor). Lumps come in different sizes and shapes. Fluid-filled cysts are usually smooth and rounded, with clear, defined edges and are not cancer. Lumps that have a jagged outline and an irregular shape are of more concern.
Calcifications. There are two types of breast calcifications, or calcium deposits:
- Macrocalcifications, which look like small white dots on a mammogram. They are often caused by aging, an old injury, or inflammation and are usually benign.
- Microcalcifications, which look like white specks on a mammogram. If found in an area of rapidly dividing cells or grouped together in a certain way, they may be a sign of DCIS or breast cancer.
Dense breast tissue: A dense breast has relatively less fat and more glandular and connective tissue. This mammogram finding is both common and normal, especially among younger women and women who use menopausal hormone therapy. Dense breast tissue can make a mammogram more difficult to interpret because both dense breast tissue and breast tumors appear as solid white areas in the image.

What happens if my mammogram is normal?

Continue to get mammograms according to recommended time intervals. Mammograms work best when they can be compared with previous ones. This allows the radiologist to compare them to look for changes in your breasts.

What happens if my mammogram is abnormal?

An abnormal mammogram does not always mean that there is cancer. But you will need to have additional mammograms, tests, or exams before the doctor can tell for sure. You may also be referred to a breast specialist or a surgeon. It does not necessarily mean you have cancer or need surgery. These doctors are experts in diagnosing breast problems. Doctors may order some of these tests:

Diagnostic mammogram, to focus on a specific area of the breast
Ultrasound, an imaging test that uses sound waves to create a picture of your breast. The pictures may show whether a lump is solid or filled with fluid. A cyst is a fluid-filled sac. Cysts are not cancer. But a solid mass may be cancer. After the test, your doctor can store the pictures on video or print them out. This exam may be used along with a mammogram.
Magnetic resonance imaging (MRI), which uses a powerful magnet linked to a computer. MRI makes detailed pictures of breast tissue. Your doctor can view these pictures on a monitor or print them on film. MRI may be used along with a mammogram.
Biopsy, a test in which fluid or tissue is removed from your breast to help find out if there is cancer. Your doctor may refer you to a surgeon or to a doctor who is an expert in breast disease for a biopsy.

What is the Breast Imaging Reporting and Database System (BI-RADS®)?

The American College of Radiology (ACR) has established a uniform way for radiologists to describe mammogram findings. The system, called BI-RADS, includes seven standardized categories, or levels. Each BI-RADS category has a follow-up plan associated with it to help radiologists and other physicians appropriately manage a patient’s care.

Breast Imaging Reporting and Database System (BI-RADS)

Category	Assessment	Follow-up
0	Need additional imaging evaluation	Additional imaging needed before a category can be assigned
1	Negative	Continue regular screening mammograms
2	Benign (noncancerous) finding	Continue regular screening mammograms
3	Probably benign	Receive a 6-month follow-up mammogram
4	Suspicious abnormality	May require biopsy
5	Highly suggestive of malignancy (cancer)	Requires biopsy
6	Known biopsy-proven malignancy (cancer)	Biopsy confirms presence of cancer before treatment begins

BI-RADS also includes four categories of breast density that may be reported. 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:

The breasts are almost entirely fatty
There are scattered areas of dense glandular tissue and fibrous connective tissue (together known as fibroglandular density)
The breasts are heterogeneously dense, which means they have more of these areas of fibroglandular density. This may make it hard to see small masses in the breast tissue on a mammogram.
The breasts are extremely dense, which makes it hard to see tumors in the breast tissue on a mammogram.

Many states in the U.S. have enacted laws requiring mammography providers to tell women if they have dense breasts (i.e., breasts that are heterogeneously or extremely dense on a mammogram) and to inform them of risks associated with having dense breasts. In addition to making mammograms harder to read, dense breasts are a risk factor for breast cancer.

Although they are not perfect, mammograms are the best method to find breast changes that cannot be felt. If your mammogram shows a breast change, sometimes other tests are needed to better understand it. Even if the doctor sees something on the mammogram, it does not mean it is cancer.
As with any medical test, mammograms have limits. These limits include:
- They are only part of a complete breast exam. Your doctor also should do a clinical breast exam. If your mammogram finds something abnormal, your doctor will order other tests.
- Finding cancer does not always mean saving lives. Even though mammography can detect tumors that cannot be felt, finding a small tumor does not always mean that a woman's life will be saved. Mammography may not help a woman with a fast growing cancer that has already spread to other parts of her body before being found.
- False negatives can happen. This means everything may look normal, but cancer is actually present. False negatives don't happen often. Younger women are more likely to have a false negative mammogram than are older women. The dense breasts of younger women make breast cancers harder to find in mammograms.
- False positives can happen. This is when the mammogram results look like cancer is present, even though it is not. False positives are more common in younger women, women who have had breast biopsies, women with a family history of breast cancer, and women who are taking estrogen, such as menopausal hormone therapy.
- Mammograms (as well as dental x-rays and other routine x-rays) use very small doses of radiation. The risk of any harm is very slight, but repeated x-rays could cause cancer. The benefits nearly always outweigh the risk. Talk to your doctor about the need for each x-ray. Ask about shielding to protect parts of the body that are not in the picture. You should always let your doctor and the technician know if there is any chance that you are pregnant.

Top Four Mammogram Myths

Knowing the truth about mammograms could help save your life, or the life of someone you love. Over 60% of breast cancer cases are diagnosed before they spread. Nearly 90% of women who find and treat their breast cancer are cancer-free at five years. Mammograms can help reduce the number of deaths from breast cancer among women ages 40 to 70.

Breast Cancer Screening & Diagnosis

Breast cancer is one of the most common cancers among women in the U.S., with about 1 in 8 women developing the disease within her lifetime. Breast cancer is an uncontrolled growth of breast cells that has the potential to spread into the breast and possibly to other parts of the body. Early detection through screening saves the lives of thousands of women every year. If there is a history of breast cancer in the family, women should consider the BReast CAncer susceptibility test (or BRCA) to identify a gene that may indicate an increased risk of developing the disease. Women forty and over should be screened for abnormalities yearly to detect and evaluate changes in breast tissue. If an abnormality is found, a biopsy and pathological exam are necessary for a definitive diagnosis and prognosis. After diagnosis, your doctor may want to learn more about your specific cancer through immunohistochemistry (IHC) and HER2 protein tests. IHC testing can help determine if a specific abnormality is present in the cancer cells. HER2 tests can tell your physician if the breast cancer is turned on by the HER2 gene, and can help determine the best course of treatment. Knowing what type of breast cancer is involved, what stage the cancer is, and the characteristics of that specific cancer, allows a woman's physician to determine best possible therapy for her individual case.

Use the slider below to see how your results affect your health.
Your result is Normal.
A normal biopsy means that no cancer or abnormal cells were found.
Related conditions
You may need a breast biopsy if:
- You or your health care provider felt a lump, thickening, or other change in your breast.
- A mammogram, ultrasound, or MRI test shows a lump, calcium deposits, or other signs that might mean cancer.
- The skin on your breast or nipple is red, scaly, or swollen, or your nipple is pulled inward.
- You have a discharge of abnormal fluid coming from your nipple.
If your provider suggests that you have a breast biopsy, it doesn't mean you have breast cancer. Most breast lumps and other changes that are checked with biopsies turn out to be benign, which means they are not cancer.
There are three main types of breast biopsy procedures. They are usually done on an outpatient basis, which means you go home the same day:
- Fine needle aspiration biopsy uses a very thin needle to remove a sample of breast cells or fluid. The biopsy takes about 15 minutes.
- Core needle biopsy uses a wide needle to remove one or more small tissue samples about the size of a grain of rice. Sometimes a small vacuum probe is used instead of a needle. The device gently suctions some tissue and removes it with a small rotating blade. A core needle biopsy takes between 15 minutes and an hour, depending on how it's done.
- Surgical biopsy (or open biopsy) is surgery to remove all or part of a lump. The biopsy usually takes about an hour.
Biopsies are often done using mammography, ultrasound, MRI, or x-rays to help see exactly where to take the tissue sample. Your procedure will vary depending on which method is used to guide the biopsy, but the general steps are usually the same.
For a fine needle aspiration biopsy or a core needle biopsy:
- Your provider will clean the skin on your breast and give you a shot of medicine to numb the area, so you won't feel any pain. The shot may sting briefly.
- You may be sitting or lying down. If images are used to guide the biopsy, you may lie on your side, back, or belly with your breast over an opening on the table.
- For a fine needle aspiration biopsy, your provider will insert the needle into the biopsy site and remove a sample of cells or fluid. For a core biopsy, a tiny cut may be made to insert a wide needle or a vacuum device. You may feel a little pressure when the sample or samples are removed.
- Pressure will be applied to area until the bleeding stops.
- Your provider will cover the biopsy site with a sterile bandage. If you had a small incision, small strips of medical tape may be used to close the wound.
For a surgical biopsy:
- You'll lie on an operating table. You may have an IV (intravenous line) in your arm or hand that may be used to give you medicine to relax. The skin over the biopsy area will be cleaned.
- To prevent pain, you'll have either:
  A shot of medicine to numb your breast. The shot may sting briefly.
  General anesthesia, which is medicine given through an IV to make you sleep.
- When you are numb or asleep, the surgeon will make a small cut in your breast tissue to remove part or all of the lump. In certain cases, tissue around the lump may also be removed. This may help avoid the need for more surgery if cancer cells are found in the lump.
- The cut in your skin will be closed with small strips of medical tape or stitches and covered with a sterile bandage.
The type of biopsy you have will depend on:
- The size and location of the suspicious tissue in your breast
- How many areas of your breast are involved
- How abnormal the tissue looks on a mammogram or other image
- Your general health and preferences
Ask your provider about why you need a biopsy and which type is right for you.
It's common to have some bruising and temporary discomfort after a breast biopsy. Possible risks include:
- Infection, which can be treated with antibiotics
- Bleeding
Your provider will give you instructions for how to care for biopsy area and manage any discomfort. If you're having general anesthesia, talk with your provider about how it may affect you. General anesthesia is very safe even for most people with other health conditions.
It may take several days to a week to get your biopsy results. The results are called a pathology report. The report is written for your provider and will include a lot of medical terms. Your provider can explain what your report means.
The most important part of your report will be the diagnosis. In general, your results will be one of these categories:
- Normal. No cancer or abnormal cells were found.
- Abnormal breast changes that aren't cancer and don't increase your risk for breast cancer. Some of these conditions often get better on their own and others may need treatment.
- Abnormal breast changes that increase your risk for breast cancer. These cells are not cancer, but if you have them, you are more likely to develop cancer.
  If you had a needle biopsy that diagnosed a condition that increases your breast cancer risk, you may need a surgical biopsy to remove all the abnormal tissue. To find out what you can do to reduce your breast cancer risk, you will likely see a doctor who specializes in breast cancer.
- Breast cancer. If your biopsy finds cancer cells, your report will include details about how fast the cancer cells are growing, how much they look like normal cells, and other information to help plan the most effective treatment for your type of cancer. Usually, a doctor who specializes in breast cancer will provide your care.

Ultrasound Guided Breast Biopsy 1

Ultrasound image of possible breast tumor before biopsy. The procedure is performed by a radiologist and sonographer. A local anesthetic is injected into the breast. The transducer is pressed to the breast and the suspicious area is located. The biopsy needle is inserted in the breast and guided in realtime by watching its movement through the breast on a computer monitor. The tissue sample is taken and the needle is removed.

Breast Cancer Biopsy

If a woman has symptoms of breast cancer (such as a lump), or if a suspicious area is found in an imaging exam, the next step is to physically examine the breasts by noting any changes in their appearance and palpating the breast and the underarm region. A complete physical exam may be done as well. If symptoms or results of these exams suggest cancer might be present, then further tests will be done. (Note: The following diagnostic procedures are common to the US; procedures may vary in other countries.)

Your result is Normal.
A normal result means that no abnormalities or masses were found in your breast tissue.
Related conditions
Your doctor may want to order this test in the following situations:
- As the first test to examine young women (usually less than 35-year-old) who have breast symptoms, such as pain, lumps, or abnormal nipple discharge
- As a follow-up test if a clinical breast exam or mammogram has revealed an abnormality
- To evaluate breast tissue that is obscured by breast implants
- To evaluate breast tissue in pregnant women
- To guide the placement of a needle during breast biopsies
It is important to point out that a breast ultrasound is not usually done to screen for breast cancer because some early signs of cancer can be easily missed with this test.
A normal result means that no abnormalities or masses were found in your breast tissue.
An abnormal result indicates that a problem was detected, including but not limited to:
- Cysts, which are fluid-filled sacs
- Solid tumors, which can be cancerous or non-cancerous
- Fibroadenomas (non-cancerous solid growths)
- Lipomas (non-cancerous fatty tumors)
