Time Trends in Breast Cancer Among Indian Women Population: An Analysis of Population Based Cancer Registry Data

Meesha Chaturvedi et al. Indian J Surg Oncol. 2015 Dec.

Abstract

Background: The trends observed in cancer breast among Indian women are an indication of effect of changing lifestyle in population. To draw an appropriate inference regarding the trends of a particular type of cancer in a country, it is imperative to glance at the reliable data collected by Population Based Cancer Registries over a period of time.

Objective: To give an insight of changing trends of breast cancer which have taken place over a period of time among women in Cancer Registries of India. Breast Cancer trends for invasive breast cancer in women in Indian Registries have varied during the selected period. Occurrence of breast cancers has also shown geographical variation in India.

Materials and methods: This data was collected by means of a 'Standard Core Proforma' designed by NCRP conforming to the data fields as suggested by International norms. The Proforma was filled by trained Registry workers based on interview/ hospital medical records/ supplementing data by inputs from treating surgeons/radiation oncologists/involved physicians/pathologists. The contents of the Proforma are entered into specifically created software and transmitted electronically to the coordinating center at Bangalore. The registries contributing to more number of years of data are called as older registries, while other recently established registries are called newer registries.

Results: While there has been an increase recorded in breast cancer in most of the registries, some of them have recorded an insignificant increase. Comparison of Age Adjusted Rates (AARs) among Indian Registries has been carried out after which trends observed in populations covered by Indian Registries are depicted. A variation in broad age groups of females and the proneness of females developing breast cancer over the period 1982 to 2010 has been shown. Comparisons of Indian registries with International counterparts have also been carried out.

Conclusions: There are marked changes in incidence rates of cancer breast which have occurred in respective registries in a developing country like India. A steady increase in AARs in most of the registries of India including the newly established registries is indicative of the fact that cancer breast poses a threat to women in India.
