Regular Screening
- All screening tests have false positive results and false
negative results, meaning that you could have a cancer that is missed, or a benign lump could be misdiagnosed as a cancer..
- Breast self-exam (BSE) is an important part of
screening for breast lumps. Studies have shown that self-exams do not reduce breast cancer death rates, but at least 40% of breast cancers are identified by women doing self-exams. A recent spate of inaccurate media reporting about BSE has been in the news.
- Mammograms have about a 90% accuracy. If you
have a breast lump that persists despite a normal mammogram, further studies, often including a biopsy, should be done. Baseline mammograms should be obtained between 35 and 40, then every 1- 2 years until 50, then every year. If you have a mother or sister with breast cancer, begin annual mammograms 10 years before their diagnosis was made.
- Digital mammograms represent a new technology
that may be helpful in identifying breast cancers in younger women with dense breasts. Computer Aided Detection is being used more frequently in an attempt to improve the accuracy of mammograms.
- MRI or magnetic resonance imagery is a sensitive
tool but is extremely expensive and has a high number of false positives. MRIs in conjunction with mammograms are recommended only for women at the highest risk, meaning with a genetic mutation or a strong family history of breast or ovarian cancer.
- Ultrasound is used to determine whether a lump is a
cyst (sac containing fluid) or a solid mass. If it is found to be a cyst, fluid may be withdrawn from it using a needle and syringe (a process called aspiration). If clear fluid is removed and the mass completely disappears, no further treatment or evaluation is needed. Ultrasound can also be used to locate the position of a lump to guide a biopsy or aspiration.Ultrasound helps confirm correct needle placement. By itself, current ultrasound technology does not replace mammograms in the detection of breast cancer.
- Breast-specific gamma camera is sometimes
recommended in case of newly diagnosed breast cancer, indeterminate breast cancer, very dense breasts, in women at high risk or in women in whom the previous cancer was missed by mammography.
