Cancers are major contributors to mortality among women in developing countries, with patterns changing over time. This study was done to ascertain the changes in trends and patterns of breast, cervical and ovarian cancers in women over two periods of one decade each, thirty-five years apart. Data on breast, cervical and ovarian cancers in Nigerian women over the two ten-year periods were obtained from the Ibadan Cancer Registry, using a well-structured proforma with extraction of information such as age, cancer sites and year of presentation. The extracted data were analyzed and related to information provided by the International Agency for Research on Cancer (IARC). There were about 400 cases of breast, cervical and ovarian cancers from 1960 to 1969 with cervical cancer having the highest relative frequency, while about 3000 cases of these cancers were reported from 2004 to 2013, with breast cancer having the highest ratio frequency. The age group with the highest frequencies for the three cancer types from 2004 to 2013 was 40 - 49 years, while it was 60 - 69 years from 1960 to 1969. Mean ages at presentation were 48.96 ± 13.32, 54.40 ± 13.41 and 44.42 ± 16.99 years for breast, cervical and ovarian cancers respectively. Breast and cervical cancers are the two commonest cancers in Nigerian women over the five-decade period, with breast cancer overtaking cervical cancer as the most frequently diagnosed. The number of cancer cases recorded increased seven-fold and the peak age group at diagnosis of breast cancer dropped by about twenty years over the period.
癌症是发展中国家女性死亡的主要原因，且模式随时间变化。本研究旨在确定相隔35年的两个十年期间，女性乳腺癌、宫颈癌和卵巢癌的趋势和模式变化。通过使用结构良好的表格，从伊巴丹癌症登记处获取尼日利亚女性在这两个十年期间乳腺癌、宫颈癌和卵巢癌的数据，提取年龄、癌症部位和就诊年份等信息。对提取的数据进行分析，并与国际癌症研究机构（IARC）提供的信息相关联。1960年至1969年约有400例乳腺癌、宫颈癌和卵巢癌病例，其中宫颈癌相对频率最高；而2004年至2013年报告了约3000例这些癌症病例，其中乳腺癌比例频率最高。2004年至2013年这三种癌症类型频率最高的年龄组为40 - 49岁，而1960年至1969年为60 - 69岁。乳腺癌、宫颈癌和卵巢癌的就诊平均年龄分别为48.96 ± 13.32岁、54.40 ± 13.41岁和44.42 ± 16.99岁。在这五十年期间，乳腺癌和宫颈癌是尼日利亚女性中最常见的两种癌症，乳腺癌已超过宫颈癌成为最常诊断出的癌症。在此期间，记录的癌症病例数增加了七倍，乳腺癌诊断的高峰年龄组下降了约20岁。
