The incidences of breast cancer (BC) and cervico-uterine cancer (CC) vary widely from country to country. In Mexico, BC mortality has doubled in the last 20 years to become the second leading cause of death for women aged 30 to 54 years. CC is the most common cause of death from neoplasia in women over 25 years old. In 2006, the state of Nayarit had one of the highest mortality rates for these types of cancers in Mexico.
To analyze and characterize the current demographics and morbidities associated with BC and CC in the state of Nayarit.
In this retrospective study, the clinical histories of patients who were diagnosed with BC or CC at the State Cancer Center from January 2006 to December 2010 were analyzed.
A total of 406 patients with BC and 328 patients with CC were registered. The most common clinical stage for both cancer types was IIB. The municipalities of San Pedro Lagunillas and El Nayar presented the highest prevalences of BC and CC, respectively.
Our results suggest that women living in poorer and more marginalized regions have a higher possibility of developing BC and CC. Because BC and CC are preventable and treatable in their early stages, demographic information from population records for these cancers is helpful in determining the incidence rates and patterns and improving decision-making processes.
乳腺癌（BC）和宫颈癌（CC）的发病率在不同国家之间差异很大。在墨西哥，乳腺癌死亡率在过去20年中翻了一番，成为30至54岁女性的第二大死因。宫颈癌是25岁以上女性肿瘤死亡的最常见原因。2006年，纳亚里特州是墨西哥这类癌症死亡率最高的地区之一。
分析和描述纳亚里特州与乳腺癌和宫颈癌相关的当前人口统计学和发病率。
在这项回顾性研究中，分析了2006年1月至2010年12月期间在州癌症中心被诊断为乳腺癌或宫颈癌的患者的临床病史。
共登记了406例乳腺癌患者和328例宫颈癌患者。两种癌症最常见的临床分期均为IIB期。圣佩德罗拉古尼利亚斯市和埃尔纳亚尔市分别是乳腺癌和宫颈癌患病率最高的地区。
我们的结果表明，生活在较贫困和边缘化地区的女性患乳腺癌和宫颈癌 的可能性更高。由于乳腺癌和宫颈癌在早期是可预防和可治疗的，这些癌症的人口记录中的人口统计信息有助于确定发病率和模式，并改善决策过程。
