Using the Florida Cancer Data System, trends were examined in female breast cancer incidence and stage of diagnosis over the period 1981-1989. The crude incidence rate increased 20% due to diagnosis at local stage or in situ. Incidence rates of disease with regional or distant spread have declined. Similar trends appear in all age groups statewide and in both Hispanic and non-Hispanic whites. The shift to earlier stage at diagnosis is not seen for nonwhite women who are less likely to be diagnosed at a local stage than white women, even after controlling for the younger age distribution of nonwhite cases. For non-Hispanic whites, the percent local at diagnosis is lowest in women in urban counties. Careful breast examination and mammographic screening for asymptomatic women lead to earlier diagnosis, longer survival and even cure. While considerable progress has been made in early detection, nonwhites and some urban residents in Florida have not received the full benefit of these changes.
利用佛罗里达癌症数据系统，对1981年至1989年期间女性乳腺癌发病率及诊断分期的趋势进行了研究。由于局部阶段或原位癌的诊断，粗发病率上升了20%。区域或远处转移疾病的发病率有所下降。全州所有年龄组以及西班牙裔和非西班牙裔白人中均出现了类似趋势。非白人女性在诊断时向更早阶段的转变并不明显，即使在控制了非白人病例较年轻的年龄分布后，她们在局部阶段被诊断出的可能性仍低于白人女性。对于非西班牙裔白人，城市县女性在诊断时的局部比例最低。对无症状女性进行仔细的乳房检查和乳房X光筛查可实现更早诊断、延长生存期甚至治愈。虽然在早期检测方面取得了相当大的进展，但佛罗里达州的非白人和一些城市居民并未充分受益于这些变化。
