Objectives. This study examined times to diagnosis and treatment for medically underserved women screened for breast cancer. Methods. Intervals from first positive screening test to diagnosis to: initiation of treatment were determined for 1659 women 40 years and older diagnosed with breast cancer. Results. Women with abnormal mammograms had shorter diagnostic intervals than women with abnormal clinical breast examinations and normal mammograms. U'onlen with selfreport breast symptoms bad shorter diagnostic intervals than asymptomatic women. Diagnostic intervals were less than 60 days in 78% of cases. Treatment intervals were generally 2 weeks or less. Conclusions. Most omen diagnosed with breast cancer were followed up in a timely manner after screening. Further investigation is needed to identify and then address factors associated with longer diagnostic and treatment intervals to maximize the benefits of early detection.
