What is a screening test?
A screening test is used to find diseases, such as cancer, in people who do not have signs or symptoms. This allows early treatment. The earlier cancer is treated, the greater the chance of survival.
What screening tests are used to screen for breast problems?
Screening for breast problems includes mammography, clinical breast exams, and breast self-awareness.
What is mammography?
Mammography is an X-ray technique used to study the breasts. No dyes have to be injected or swallowed, and no instru-ments will be put in your body.
Why is mammography done?
Mammography is done for two reasons: 1) as a screening test to regularly check for breast cancer in women who do not have signs or symptoms of the disease, and 2) as a diagnostic test to check lumps or other symptoms that you have found yourself or that have been found by a health care provider.
When should I start having annual mammograms?
Age 40 years is recommended as the starting point in order to find cancer at an early and more treatable stage.
What if the result of my mammography reveals a lump?
Mammography by itself cannot tell whether a lump or other finding is benign (not cancer) or malignant (cancer). If a mammography finding is suspicious for cancer, a biopsy is needed to confirm that cancer is present. In a biopsy, the lump or a small sample of cells from the lump is removed and looked at under a microscope.
How do I prepare for a mammogram?
The day you have a mammogram, do not wear powders, lotions, or deodorants. Most of these products have substances that can be seen on the X-ray and make it hard to read.
What happens during mammography?
To get ready for the test, you will need to completely undress from the waist up and put on a gown. You will be asked to stand or sit in front of the X-ray machine. One of your breasts will be placed between two smooth, flat plastic or glass plates. You will briefly feel firm pressure on your breast. The plates will flatten your breast as much as possible so that the most tissue can be viewed with the least amount of radiation. After the first X-ray, the plates may be removed so that another X-ray can be obtained from one or more other positions. The test then is done on the other breast.
What are the risks of mammography?
You may be concerned about the risk of cancer from the radiation used in mammography. Mammography uses a low level of radiation. The risk of harm from the level of radiation used in mammography is low. Having a yearly screening mammogram does not increase cancer risk.
What is digital mammography?
Digital mammography is a type of mammography technique. It differs from standard mammography only in the way the image is stored. Instead of using film, the image in digital mammography is stored as a digital file on a computer. A computer program allows the image to be enlarged or enhanced or specific areas to be magnified.
What is a clinical breast exam?
Your health care provider will examine your breasts during routine checkups. This is called a clinical breast exam. Women aged 29–39 years should have a clinical breast exam every 1–3 years. Women aged 40 years and older should have one every year.
How is a clinical breast exam done?
The exam may be done while you are lying down, sitting up, or both. You may be asked to raise your arms over your head. The breasts are first checked for any changes in size or shape. Your health care provider also looks for puckers, dimples, or redness of the skin. He or she then feels for changes in each breast and under each arm. The nipple may be gently squeezed to check for discharge.
What is breast self-awareness?
Breast self-awareness is an understanding of how your breasts normally look and feel.
How is breast self-awareness different from the traditional breast self-exam?
In the traditional breast self-exam, you use a precise method to examine your breasts on a regular basis, such as once a month. Breast self-awareness does not require you to examine your breasts once a month or with a precise method. Instead, it focuses on having a sense of what is normal for your breasts so that you can tell if there are changes—even small changes—and report them to your health care provider.
