Time Trend in Breast and Cervix Cancer of Women in India, (1990-2003)

Abstract

The Indian Council of Medical Research (ICMR) started a National Cancer Registry Programme (NCRP)in the year 1982 with the main objective of generating reliable data on the magnitude and pattern of cancer inIndia. There are about 20 Population Based Cancer Registries (PBCR) which are currently functioning underthe network of NCRP. The present paper aims to provide the time trends in the incidence of breast and cervixcancer among females of India. The incidence data collected by Bangalore, Barshi, Bhopal, Chennai, Delhi andMumbai over the period 1990 to 2003 formed the sources of data. In the year 1990, cervix was the leading site ofcancer followed by breast cancer in the registries of Bangalore (23.0% vs. 15.9%), Bhopal (23.2% vs. 21.4%),Chennai (28.9% vs. 17.7%) and Delhi (21.6% vs. 20.3%), while in Mumbai breast was the leading site of cancer(24.1% vs. 16.0%). By the years 2000-3, the scenario had changed and breast had overtaken as the leading siteof cancer in all the registries except in Barshi (16.9% vs. 36.8%). The time trend analysis for these sites suggesteda significant decreasing trend in the case of cervix in Bangalore and Delhi registries, while the registries ofBhopal, Chennai and Mumbai did not show any significant changes. However, in the case of breast cancer, asignificant increasing trend was observed in Bhopal, Chennai and Delhi registries with Bangalore and Mumbairegistries demonstrating no such significant changes. Histopathologic confirmation for both malignancies wasfound to be more than 80% in these registries. It is concluded that in India the cervix cancer rates are decreasingwhile breast cancer is on the increase.
