Abstract 1085


The objectives of this study of time trends in Breast Cancer are to apply for Cancer Control Strategies and to identify any change in risk factors.


The National Cancer Registry Programme was established by the Indian Council of Medical Research in 1982. Since then systematic data have been collected. The data checks as per international standards and measures to ensure complete coverage of data as far as possible are in place. Data of six older cancer registries have been examined for trends in incidence rates.


Cancer of the breast is rapidly replacing cancer cervix as the number one cancer in women. Approximately 100,000 new cases of cancer breast occur in India as of the year 2015. The incidence rates on breast cancer in India have been increasing in the past three decades. Data from the Population Based Cancer Registries (PBCRs) for the past three decades show as statistically significant increase in incidence rates in Bangalore (Annual Percentage Change (APC) = 3.3%), Bhopal (APC = 1.7%), Chennai (APC = 2.4%), Delhi (APC= 1.1%) and Mumbai (APC = 1.3%). Post menopausal women (above 45 years of age) showed a greater increase in the PBCRs rate in Bangalore and Chennai. Late age at marriage, obesity less number of children and changing life style among women could be hypothetical factors that are contributing to the increasing incidence rates. Even the rural cancer registry in Barshi has shown a non-significant increase in breast cancer incidence rates.


The assessment of cancer trends based on the cancer incidence rates over a selected time period is the only way to distinguish the impacts of changing population and changing risks. There by changing country cancer control strategies in both prevention and treatment.
