Data on incidence, prevalence, and disease specific mortality are frequently incomplete, not very reliable or are lacking in many countries particularly in Asia and Africa. In the absence of dependable data from the Civil Registration System (CRS), many countries have developed their own Sample Registration System (SRS). Due to several socio-economic constraints cause is not adequately noted in the death certificates. Sample registration system practice in India helps in this but for correlating with cancer registry data this is not the optimal. When cancer morbidity figures from SRS system and cancer registry are compared the SRS figures are low. Reasons for fewer cancer deaths in Municipal Corporation reports may be due to that they only look at primary cause of death and overlook the secondary or underlying causes. There are also a number of reasons for under-registration of cancer deaths in cancer registries but they nevertheless give a more accurate picture. Many registries collect follow-up information for survival studies, which is also helpful to improve cancer mortality data. Tumour registries also represent important resources for rapid identification of cancer survivors for research studies.
关于发病率、患病率和疾病特异性死亡率的数据在许多国家，尤其是亚洲和非洲，常常不完整、不太可靠或根本没有。由于缺乏民事登记系统（CRS）的可靠数据，许多国家建立了自己的抽样登记系统（SRS）。由于一些社会经济限制因素，死亡证明中未充分注明死因。印度的抽样登记系统实践对此有所帮助，但要与癌症登记数据相关联，这并非最佳选择。当比较SRS系统的癌症发病率数据和癌症登记数据时，SRS的数据较低。市政公司报告中癌症死亡人数较少的原因可能是他们只关注主要死因，而忽略了次要或潜在死因。癌症登记中癌症死亡登记不足也有多种原因，但它们仍能提供更准确的情况。许多登记处收集用于生存研究的随访信息，这也有助于改善癌症死亡率数据。肿瘤登记处也是快速识别癌症幸存者以进行研究的重要资源。
