In November 1998, the Task Force clarified the wording
of the recommendation on screening mammography and clinical breast examination
for women aged 50-69. The best available evidence regarding screening
interval is limited and does not provide conclusive direction regarding
screening annually versus every two years. The revised wording for
the recommendation reflects the inconclusive nature of the available evidence.
| MANEUVER | EFFECTIVENESS | LEVEL OF EVIDENCE <REF> | RECOMMENDATION |
| Clinical examination and mammography, women aged 50-69 years. | Routine clinical examination and mammography reduces mortality from breast cancer. Optimum frequency of screening has not been determined. | Randomized controlled trials <1> (I) | There is
good evidence for screening women aged 50-69 years by clinical examination
and mammography (A). The best available data support screening every 1-2
years.
