mammography
[mah-mog´rah-fe]The American Cancer Society recommends that a baseline mammogram be done between the ages of 35 and 40 for later comparisons if needed. A yearly mammogram is recommended for women over the age of 50 to screen for breast cancer that may not be discovered during other types of breast examination.
mammography
The radiologic examination of the breast using a dedicated device designed specifically for imaging the breast. Mammography is the single best noninvasive screening procedure for detecting breast cancer: it yields a false negative rate of 5–15% and a false positive of 10%. 24% of biopsies of non-palpable breast masses with calcification (> 15 calcifications or calcifications in a linear or branching fashion) have ductal or lobular carcinoma.Guidelines for mammography
National Cancer Advisory Board (US)
• High risk women—annual mammogram (MG) breast self-examination (BSE), < age 40.
• Average risk women—annual MG & BSE, age 40–49.
• Low risk women—annual MG & BSE, > age 50.
American Cancer Society and the National Cancer Institute (US)
BSE after age 20, a baseline MG between ages 35–45, and annual or biennial MG thereafter.
Frequency of mammography is a function of the person’s risk factors for BC:
• First-degree relative with BC;
• Caucasian;
• Later pregnancy.
Mammography categories (American College of Radiologists)
0—Incomplete, additional imaging evaluation needed.
1—Negative.
2—Benign finding.
3—Probably benign, short follow-up interval suggested.
4—Suspicious abnormality, biopsy should be considered.
5—Highly suggestive of malignancy, appropriate action warranted.
