Oral cancer in India.

OBJECTIVES

To describe the epidemiological status of oral cancer (OC) in India along with updates on risk factors, advances and gaps in preventive measures, treatment, costs of care and monitoring.

METHODS

Two national estimates of incidence and mortality were cited, one for 2016 by the Global Burden of Disease India Study and one based on projections for 2020 by GLOBOCAN. The National Cancer Registry Project provided local and regional incidence and trends using data from 2012-2016. Scientific literature, reports of the NCRP, the IARC and government press releases were also consulted.

RESULTS

Tobacco and areca nut habits are the major risk factors for OC in India. In the 1980s, intervention studies on oral screening, awareness generation and habit cessation in rural areas reduced tobacco use and oral leukoplakia. Lately, adoption of the tobacco control law and mass media communications have resulted in decreased tobacco use. However, the increasing popularity of highly carcinogenic tobacco products containing areca nut, with evasion of their bans, is increasing OC incidence.

CONCLUSION

Despite advances in care, there is growing incidence of OC, persisting poor awareness about the need to quit tobacco/areca nut/alcohol use and go for screening. Major efforts are needed to implement preventive activities.
