HPV, H. pylori, Hepatitis Viruses Among Key Infection-Linked Cancer Causes in India

New Delhi: Nearly 1.9 lakh cancer cases in India are linked to viral and bacterial infections, according to a study published in The Lancet. The findings highlight the significant role of preventable infections in the country’s cancer burden.
The study identifies human papillomavirus (HPV), Helicobacter pylori (H. pylori) and hepatitis viruses among the important infectious agents associated with cancer.
HPV is strongly linked to cervical cancer and can also contribute to cancers affecting other parts of the body. H. pylori, a bacterial infection that affects the stomach, is associated with gastric cancer, while chronic infections with hepatitis B and C viruses can increase the risk of liver cancer.
Experts say that a proportion of these cancers could potentially be prevented or detected early through a combination of vaccination, screening, diagnosis and timely treatment.
HPV vaccination is an important preventive measure against HPV-related cancers, while screening programmes can help identify precancerous changes or cancers at an earlier stage. Similarly, identifying and treating H. pylori infection can help reduce the risk of certain stomach cancers.
The findings underline the importance of integrating infection prevention and cancer-control strategies into India's public-health programmes. Improving vaccination coverage, expanding screening services and ensuring timely access to treatment could help reduce the burden of cancers associated with infectious diseases.
The study also reinforces the broader message that cancer prevention is not limited to lifestyle factors. Preventing or treating certain infections can also play an important role in reducing cancer risk.
