The Texas Breast Screening Project: Part I. Mammographic and clinical results.
The 1987 Texas Breast Screening Project was designed to educate women about the benefits and safety of mammographic screening. During the 2-week promotion, 109,339 women called toll-free telephone numbers to inquire about the program, and 64,459 (65%) of 99,650 eligible callers had $50 mammograms at 306 participating community radiology centers. Biopsies were obtained for 1,122 women (1.7% of those screened), and the ratio of benign to malignant biopsy results was 4.2:1. Among the women having biopsies, 214 cancers were found (3.3 cancers per 1,000 women screened). Forty-seven percent of the tumors were not palpable, 80% were smaller than 2 cm, and 72% were clinicopathologic stage 0 or I. These results show that women will respond to an invitation to attend mammographic screening, and that community radiology centers can detect large numbers of early, curable breast cancers.
