Cancer Burden in India: A Statistical Analysis on Incidence Rates

Abstract

Background: Cancer incidence rates are rising at an alarming rate in India and are expected to rise by 12% in the next 5 years. Hence, a thorough knowledge of the existing scope of the cancer problem is required to provide an approach for analyzing and regulating the impact of cancer across the country. Objectives: This study aimed to determine whether the cancer incidence rates of all the states and union territories across the six geographical regions of India are statistically different from each other or not and also to identify the highly cancer-affected states. Materials and Methods: The data have been obtained from the website www.indiastat.com from 2009 to 2020. The one-way analysis of variance, followed by Tukey’s test and t-test, is used for the statistical evaluation. Results: The multiple comparison tests revealed that the difference between the cancer incidence rates is significant in all the states and union territories in every region of India. The highly affected states in the six geographical regions of India are Uttar Pradesh (UP), Tamil Nadu, Bihar, Maharashtra, Assam, and Madhya Pradesh. The most highly affected state among them is UP. These states contributed to nearly half of India’s cancer burden in 2020. Conclusion: This study offers significant information on the current status of cancer incidence rates in India for 12 years. As India is observing an increase in cancer incidence, therefore, additional efforts are required to strengthen cancer prevention and control strategies, particularly in India’s most cancer-affected states.
