Half of breast cancers occur in patients older than 65 and 25% in patients aged 75 or older. Prevention and early diagnosis are a societal but also an individual issue in this population. Good guidelines for screening and prevention are available for patients up to 70, but few data are available for older patients. The present article reviews these data in an effort to provide some guidance to geriatricians and primary physicians about screening and prevention of breast cancer in their older patients. Age alone should not be used to determine when to screen; rather, life expectancy estimates can help decision-making. Patients with a life expectancy of 10 years or more are likely to benefit from mammography screening. Very few data are available for tamoxifen prevention in women older than 70. There is a need for further randomized controlled trials to clarify a host of outstanding issues in improving the prevention and the care of breast cancer in older people.
Key words: older women, breast cancer, mammography, prevention.

In the past ten years, public campaigning on behalf of breast cancer has raised awareness to new heights. Despite an increase in the incidence of breast cancer over the past twenty years (most likely due to better detection of disease), we have seen a plateau and even more recently a decline in the mortality rates in both Canada and the United States. This is likely due to our ability to diagnose disease earlier through breast screening and our improvements in treatment.

Breast Screening is indeed a major player in our fight against breast cancer. It is estimated that a significant reduction in breast cancer mortality can be achieved in Ontario if 70% of women between the ages of 50-69 were to participate in a program of early detection.

Breast cancer screening involves participation in biennial mammograms, monthly self-examination and regular breast examination by a trained professional; a regimen that should be followed during the years that the woman is most likely to be affected.
