Screening for Breast Cancer
The purpose of screening is early diagnosis and treatment. Screening tests are usually administered to people without current symptoms, but who may be at high risk for certain diseases or conditions.
Examination of your own breasts is called
Many women complain that they don’t ever feel anything or their breast is so lumpy that they wouldn’t know what something wrong would feel like. Because you can palpate your breast far more regularly than a doctor, it is very important that you do a BSE.
Focus on anything new or different. You'll be able to feel a particularly lumpy portion of the breast. Sometimes cysts appear and disappear. Masses that come and go are generally not cancerous.
The American Cancer Society has a kit that is available. It is very useful because it has model breasts in it that contain cancer both deep and superficially within the model. Other than new lumps, look for nipple discharge (either clear or bloody), dimpling of the skin, thickening of the skin, redness of the skin, pain, new lumps, or a fullness feeling in the armpit. Lastly, it is important to keep in mind that this kit is not a substitute for a clinical exam.
Clinical Breast Examination
During your routine physical examination, your doctor may do a clinical breast examination (CBE). During a CBE, your doctor will carefully feel your breasts and under your arms to check for lumps or other unusual changes.
The ability of mammography to detect cancer depends on such factors as the size of the tumor, your age, breast density, and the skill of the radiologist.
During ultrasonography, sound waves (called ultrasound) are bounced off tissues and the echoes are converted into a picture (sonogram). Ultrasound is used to evaluate lumps that have been identified by a BSE, CBE, or mammography. Ultrasounds are not used as a screening tool.
Magnetic Resonance Imaging (MRI)
The use of breast MRI has increased lately, but this test is not for all women. You and your doctor can discuss whether an MRI is the right test for you.
Screening guidelines for breast cancer—in particular, mammography—are still being debated by various professional organizations.
Recommended mammography screening guidelines from the American Cancer Society and National Cancer Institute include:
- Women should have their first screening baseline study between ages 35-40.
- Women in their 40s should be screened every 1-2 years with mammography.
- Women aged 50 and older should be screened every year.
- Women who are at higher than average risk of breast cancer should seek expert medical advice about whether they should begin screening before age 40 and the frequency of screening.
