PURPOSE
The systematic collection of data on cancer is being performed by various population-based cancer registries (PBCRs) and hospital-based cancer registries (HBCRs) across India under the ...National Cancer Registry Programme–National Centre for Disease Informatics and Research of Indian Council of Medical Research since 1982.
METHODS
This study examined the cancer incidence, patterns, trends, projections, and mortality from 28 PBCRs and also the stage at presentation and type of treatment of patients with cancer from 58 HBCRs (N = 667,666) from the pooled analysis for the composite period 2012-2016. Time trends in cancer incidence rate were generated as annual percent change from 16 PBCRs (those with a minimum of 10 years of continuous good data available) using Joinpoint regression.
RESULTS
Aizawl district (269.4) and Papumpare district (219.8) had the highest age-adjusted incidence rates among males and females, respectively. The projected number of patients with cancer in India is 1,392,179 for the year 2020, and the common 5 leading sites are breast, lung, mouth, cervix uteri, and tongue. Trends in cancer incidence rate showed an increase in all sites of cancer in both sexes and were high in Kamrup urban (annual percent change, 3.8%; P < .05). The majority of the patients with cancer were diagnosed at the locally advanced stage for breast (57.0%), cervix uteri (60.0%), head and neck (66.6%), and stomach (50.8%) cancer, whereas in lung cancer, distant metastasis was predominant among males (44.0%) and females (47.6%).
CONCLUSION
This study provides a framework for assessing the status and trends of cancer in India. It shall guide appropriate support for action to strengthen efforts to improve cancer prevention and control to achieve the national noncommunicable disease targets and the sustainable development goals.
Objective: A comprehensive coordinated effort was undertaken by National Cancer Registry Programme (NCRP) and its coordinating unit in an Indian State – Haryana, to map cancer incidence, to provide ...regional overview of geographical patterns of Cancer within state of Haryana to serve as basis for informing public and policy makers. Methods: Information on new cases, residents of Haryana state, and diagnosed with cancer during years 2016 -17 was collected from several medical set-ups in 21 districts across Haryana and its neighboring states. Data received from Hospitals registered under NCRP was also included. Age-Adjusted incidence Rates (AARs) were calculated by gender and site for each district in State. All districts were used for comparison of AARs with rates to those from established population based cancer registries. Cumulative risk of developing cancer was calculated.Results: Data from 36736 cases was collated. Comparison of AARs revealed that there are high incidence rates of head and neck cancers in males, whereas cancer breast was leading site in females. Relative proportions of cancers of sites associated with use of tobacco, were found high in some semi-urban districts of state. Project has recognized and substantiated need of setting up of screening programmes and Population Based Cancer Registry in Haryana. The study was done using an electronic data-capture methodology which is remarkably cost-effective and provides a model for health informatics in setting of developing country.Conclusion: Contiguous areas of high incidence of cancer recorded in state have shown higher rates of tobacco related cancers (Head & Neck, Lung) necessitating rigorous control on tobacco usage. Higher incidence of certain cancers associated with reproductive system of both men (prostate) and women (cervix and breast) implicates factors such as lifestyle changes due to urbanization. Overall, the project is a step towards good cancer statistics availability in the country.
Background & objectives: Information on recent cancer statistics is important for planning, monitoring and evaluating cancer control activities. This article aims to provide an update on the cancer ...incidence estimates in India by sex, age groups and anatomical sites for the year 2022.
Methods: The National Cancer Registry Programme Report 2020, reported the cancer incidence from 28 Population-Based Cancer Registries (PBCRs) for the years 2012-2016. This was used as the basis to calculate cancer estimates in India. Information pertaining to the population at risk was extracted from the Census of India (2001 and 2011) for the estimation of age-sex stratified population. PBCRs were categorised into the respective State and regions of the country to understand the epidemiology of cancer. The age-specific incidence rate for each specific anatomical site of cancer was applied to the estimated population to derive the number of cancer cases in India for 2022.
Results: The estimated number of incident cases of cancer in India for the year 2022 was found to be 14,61,427 (crude rate:100.4 per 100,000). In India, one in nine people are likely to develop cancer in his/her lifetime. Lung and breast cancers were the leading sites of cancer in males and females, respectively. Among the childhood (0-14 yr) cancers, lymphoid leukaemia (boys: 29.2% and girls: 24.2%) was the leading site. The incidence of cancer cases is estimated to increase by 12.8 per cent in 2025 as compared to 2020.
Interpretation & conclusions: The cancer incidence is continuing to increase in India. The new estimates will be helpful in planning cancer prevention and control activities through the intervention of early detection, risk reduction and management.

Ewing sarcoma is a malignant tumour found mainly in childhood and adolescence. The present study aims at analyzing the data on Ewing sarcoma cases of bone from the National Cancer Registry Programme, ...India to provide incidence, patterns, and trends in the Indian population.
The data of five Population Based Cancer Registries (PBCR) of Bangalore, Mumbai, Chennai, Bhopal and Delhi over 30 years period (1982– 2011) were used to calculate the Age Specific and Age Standardized Incidence Rates (ASpR and ASIR), and trends in incidence was analyzed by linear and Joinpoint Regression.
Ewing sarcoma comprised around 15 % of all bone malignancies. Sixty-eight percent were 0–19 years, with 1.6 times risk of tumour in bones of limbs as compared to other bones. The highest incidence rate (per million) was in the 10–14 years age group (male −4.4, female −2.9) with significantly increasing trend in ASpR observed in both sexes. Pooled ASIR per million for all ages was higher in male (1.6) than female (1.0) with an increasing rate ratio of ASIR with increase in age. Trend of pooled ASIR for all ages was significantly increased in both sexes. Twelve percent cases were reported in ≥30 years of age.
This paper has described population based measurements on burden and trends in incidence of skeletal Ewing in India. These may steer further research questions on the clinical and molecular epidemiology to explain factors associated with the increasing incidence of Ewing sarcoma bone observed in India.
Previous efforts to report estimates of cancer incidence and mortality in India and its different parts include the National Cancer Registry Programme Reports, Sample Registration System cause of ...death findings, Cancer Incidence in Five Continents Series, and GLOBOCAN. We present a comprehensive picture of the patterns and time trends of the burden of total cancer and specific cancer types in each state of India estimated as part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 because such a systematic compilation is not readily available.
We used all accessible data from multiple sources, including 42 population-based cancer registries and the nationwide Sample Registration System of India, to estimate the incidence of 28 types of cancer in every state of India from 1990 to 2016 and the deaths and disability-adjusted life-years (DALYs) caused by them, as part of GBD 2016. We present incidence, DALYs, and death rates for all cancers together, and the trends of all types of cancers, highlighting the heterogeneity in the burden of specific types of cancers across the states of India. We also present the contribution of major risk factors to cancer DALYs in India.
8·3% (95% uncertainty interval UI 7·9–8·6) of the total deaths and 5·0% (4·6–5·5) of the total DALYs in India in 2016 were due to cancer, which was double the contribution of cancer in 1990. However, the age-standardised incidence rate of cancer did not change substantially during this period. The age-standardised cancer DALY rate had a 2·6 times variation across the states of India in 2016. The ten cancers responsible for the highest proportion of cancer DALYs in India in 2016 were stomach (9·0% of the total cancer DALYs), breast (8·2%), lung (7·5%), lip and oral cavity (7·2%), pharynx other than nasopharynx (6·8%), colon and rectum (5·8%), leukaemia (5·2%), cervical (5·2%), oesophageal (4·3%), and brain and nervous system (3·5%) cancer. Among these cancers, the age-standardised incidence rate of breast cancer increased significantly by 40·7% (95% UI 7·0–85·6) from 1990 to 2016, whereas it decreased for stomach (39·7%; 34·3–44·0), lip and oral cavity (6·4%; 0·4–18·6), cervical (39·7%; 26·5–57·3), and oesophageal cancer (31·2%; 27·9–34·9), and leukaemia (16·1%; 4·3–24·2). We found substantial inter-state heterogeneity in the age-standardised incidence rate of the different types of cancers in 2016, with a 3·3 times to 11·6 times variation for the four most frequent cancers (lip and oral, breast, lung, and stomach). Tobacco use was the leading risk factor for cancers in India to which the highest proportion (10·9%) of cancer DALYs could be attributed in 2016.
The substantial heterogeneity in the state-level incidence rate and health loss trends of the different types of cancer in India over this 26-year period should be taken into account to strengthen infrastructure and human resources for cancer prevention and control at both the national and state levels. These efforts should focus on the ten cancers contributing the highest DALYs in India, including cancers of the stomach, lung, pharynx other than nasopharynx, colon and rectum, leukaemia, oesophageal, and brain and nervous system, in addition to breast, lip and oral cavity, and cervical cancer, which are currently the focus of screening and early detection programmes.

BackgroundTo provide a comprehensive assessment of women cancer in India utilizing the systematically collected data on all cancers by the National Cancer Registry Programme (NCRP).MethodsThe study ...examined 10,2287 cancer cases among women cancers providing cancer burden for major anatomical sites. Aggregated data of 28 PBCRs and 58 HBCRs under NCRP for 2012–16 was analysed for incidence rates, trends, cumulative risk of developing cancer, stage at detection and treatments offered.ResultsStudy results have found region –wide variation of women cancers by indicating highest proportions in western followed by southern region of India. North-Eastern region had lowest proportion. It was observed that breast is highest ranking cancer in most registry areas of urban agglomerations of country while cancer cervix was leading site in registries of rural areas like Barshi (15.3) and Osmanabad &Beed (13.1). States of Mizoram (23.2) and Tripura (9.5) along with Pasighat, Cachar and Nagaland. Median age of occurrence for women for these anatomical sites ranged from 45 to 60 years of age. For cancer breast, cervix and ovary –most cases were detected with regional spread. These findings were different for cancer corpus uteri where registries have reported higher proportions (49.3 %) of localized stage at detection. Loco regional cancers had higher proportions of multimodality treatments.ConclusionStudy provides a foundation for assessing the status of women cancers in the country. Variations between geographies would guide appropriate support for action to strengthen efforts to improve cancer prevention and control in underserved areas of the country. This would facilitate advocacy for better investments and research on women cancers.
Background
Population‐based cancer survival is a key indicator for assessing the effectiveness of cancer control by a health care system in a specific geographic area. Breast cancer is the most ...common cancer among women in India, accounting for over one quarter of all female cancers. The objective of this study was to estimate the 5‐year survival of female patients who were diagnosed with breast cancer between 2012 and 2015 from the existing Population‐Based Cancer Registries (PBCRs) in India.
Methods
In total, 17,331 patients who had breast cancer diagnosed between 2012 and 2015 from 11 PBCRs were followed until June 30, 2021. Active methods were used to track the vital status of registered breast cancer cases. The study conducted survival analysis by calculating the difference between the date of first diagnosis and the date of death or censoring to estimate observed survival and relative survival using the actuarial survival approach and the Ederer‐II approach, respectively.
Results
The 5‐year age‐standardized relative survival (95% confidence interval CI) of patients with breast cancer was 66.4% (95% CI, 65.5%–67.3%). Mizoram (74.9%; 95% CI, 68.1%–80.8%), Ahmedabad urban (72.7%; 95% CI, 70.3%–74.9%), Kollam (71.5%; 95% CI, 69.2%–73.6%), and Thiruvananthapuram (69.1%; 95% CI, 67.0%–71.2%) had higher survival rates than the national average. Conversely, Pasighat had the lowest survival rate (41.9%; 95% CI, 14.7%–68.6%). The 5‐year observed survival rates for localized, regional, and distant metastasis in the pooled PBCRs were 81.0%, 65.5%, and 18.3%, respectively.
Conclusions
The overall disparity in survival rates was observed across 11 PBCRs, with lower survival rates reported in Manipur, Tripura, and Pasighat. Therefore, it is imperative to implement comprehensive cancer control strategies widely throughout the country.
In the largest analysis of population‐based cancer survival to date covering 17,331 female breast cancers from 11 cancer registries in India, disparities in survival indicate that comprehensive breast cancer control strategies should be implemented across the country.
Background & objectives: The North-Eastern (NE) region has the highest incidence of cancer in India, and is also burdened by higher prevalence of risk factors and inadequate cancer treatment ...facilities. The aim of this study was to describe the cancer profile of the NE region, focussing on the cancer sites that have high incidence and to identify research priorities.
Methods: Incidence data from population-based cancer registries (PBCRs) in the North-East region (8 States) were utilized and relevant literature was reviewed to identify risk factors.
Results: Aizawl district in Mizoram had the highest incidence of cancer in men age-adjusted rate (AAR) of 269.4 per 100,000. Among women, Papumpare district of Arunachal Pradesh had the highest incidence (AAR of 219.8) in India. East Khasi Hills district in Meghalaya had the highest incidence of oesophageal cancer (AAR of 75.4 in men and 33.6 in women). Aizawl district in Mizoram had the highest incidence of stomach (AAR-44.2 in men) and Papumpare district had highest incidence of stomach (AAR 27.1 in women), liver (AAR- 35.2 in men and 14.4 in women) and cervical cancers (AAR- 27.7). Lung cancer (AAR- 38.8 in men and 37.9 in women) and gall bladder cancer incidence (AAR- 7.9 in men and 16.2 in women) were highest in Aizawl and Assam (Kamrup urban) PBCRs, respectively. Nagaland had the highest incidence of nasopharyngeal cancer (AAR of 14.4 in men and 6.5 in women), a relatively rare cancer in other regions of India. Four States (Arunachal Pradesh, Manipur, Sikkim and Tripura) in NE had only one cancer treating facility.
Interpretation & conclusions: Further research on specific aetiological factors in the region and multi-disciplinary research for development of tools, techniques and guidelines for cancer control are the need of the hour.

The Indian Council of Medical Research initiated a network of cancer registries under the National Cancer Registry Programme (NCRP) in 1981 and data collection commenced in these registries from ...January 1982. The results on incidence rates provided by the Population Based Cancer Registries (PBCRs) have shown the variation in patterns of cancer in general and that of cancer cervix in particular. Cancer of the cervix has been the most important cancer in women in India, over past two decades. All the urban Population Based Cancer Registries at Bangalore, Bhopal, Chennai, Delhi and Mumbai have shown a statistically significant decrease in incidence rates of this site of cancer. Since over 70 per cent of the Indian population resides in the rural areas, cancer cervix still constitutes the number one cancer in either sex. Based on the data of the PBCRs, the estimated number of new cancers during 2007 in India was 90.708. The relative five year survival reported some time earlier averaged 48.7 per cent.
