Some specific types of cancer still pose a severe threat to the health of Taiwanese women. This study focuses on determining the geographical locations of hot spots and causal factors related to the major categories of cancers in Taiwanese women. Cancer mortality data from 1972 to 2001 of 346 townships in Taiwan were obtained from the Atlas of Cancer Mortality. Principal component analysis was conducted to determine the primary categories of female cancers. The spatial patterns of hot spots and cold spots for each major cancer category were identified using the local indicator of spatial association. Finally, the regional differences between the hot spots and cold spots were compared to confirm the possible factors causing cancer throughout Taiwan. A total of 21 cancer types in women were divided into seven major categories, which accounted for 68.0% of the total variance. The results from the spatial autocorrelation analysis showed significant spatial clusters of the cancer categories. Based on the overall consistency of results between this study and those of previous research, this study further identified the high-risk locations and some specific risk factors for major cancer types among Taiwanese women.
某些特定类型的癌症仍然对台湾女性的健康构成严重威胁。本研究着重于确定台湾女性主要癌症类型的高发地区地理位置及相关致病因素。台湾346个乡镇1972年至2001年的癌症死亡率数据取自《癌症死亡率地图集》。进行主成分分析以确定女性癌症的主要类型。使用空间关联局部指标识别每种主要癌症类型的热点和冷点空间模式。最后，比较热点和冷点之间的区域差异，以确定全台湾可能导致癌症的因素。女性的21种癌症类型共分为七大类，占总方差的68.0%。空间自相关分析结果显示癌症类别存在显著的空间聚集。基于本研究与以往研究结果的总体一致性，本研究进一步确定了台湾女性主要癌症类型的高危地区及一些特定风险因素。
