Cancer Trends in Different Zones of India

Abstract Introduction: The incidence of cancer has doubled between 1990-2016 and the crude DALY has also increased by 25.3%. Neoplasms are the seventh leading cause of death in the country. Women are largely affected by cancer of the breast, cervix uteri and men are commonly affected by cancer of the lungs, lip-oral, stomach, colorectal and esophagus. Cancer trends helps to identify patterns and progress of disease which will further aid research, policy decisions and clinical practice/ services. The aim of this paper is to identify the cancer trends in different zones of India. Methodology: A secondary review was conducted by reviewing published literature/ articles using search engines- google scholar and PubMed. National and international reports like Medically Certified Cause Disease, National Cancer Registry Program Report, GLOBOCAN cancer statistics report. Results: Northeastern zone of India has the highest cancer incidences with some of the highest Crude rates (per 1 lakh population) reported across the country. Among males' crude rates was observed to be- in Aizawl district (206.2), followed by Kamrup urban (190.5) and Mizoram state (146.1) and among females Aizawl district (174.6). The second highest incidences and crude rates were reported from the Southern Zone of India- for males- Thiruvananthapuram district (170.4), Kollam district (159.4) and for females- Thiruvananthapuram district (164.8), Chennai (141.4) and Kollam district (139.1). Conclusion: Incidences of cancer are rising in India with most cases occurring from the northeast and southern zones of India.
