Study Reveals 73% of Mouth Cancers in Indian Women Linked to Smokeless Tobacco
A recent study highlights the alarming prevalence of smokeless tobacco in mouth cancers among Indian women, with significant implications for public health.
73.4% of mouth cancers in women are linked to tobacco use, primarily smokeless forms.
Smokeless tobacco accounts for 57.3% of mouth cancers in men, with significant regional variations.
The study calls for enhanced tobacco cessation services to combat rising cancer rates.
A comprehensive study published in the Indian Journal of Medical Research has revealed that smokeless tobacco is responsible for approximately 73.4% of mouth cancers among women in India. This alarming statistic underscores the urgent need for public health interventions targeting tobacco use, particularly in regions where smokeless products are prevalent.
The research, titled 'Head and Neck Cancer Burden Attributable to Tobacco Use in India: National and Region-wise Estimates,' analyzed data from 11,285 patients diagnosed with head and neck cancers and 7,154 individuals with non-cancerous conditions at the Regional Cancer Centre in Thiruvananthapuram, Kerala, between 2019 and 2024. The findings indicate a stark gender disparity in tobacco-related cancer risks, with men showing a 57.3% association of mouth cancers with smokeless tobacco.
Among the male population, smokeless tobacco contributed to 61.8% of lip cancers and 30.7% of tongue cancers. Conversely, smoking was linked to 40.2% of cancers at the base of the tongue and 45.7% of hypopharyngeal cancers. The study's authors noted that smokeless tobacco poses a direct risk to oral tissues, leading to prolonged exposure to carcinogens, which may explain the higher incidence rates observed in users.
The implications of these findings are significant for public health in India, particularly in states with high rates of smokeless tobacco use. For instance, in Chhattisgarh and Odisha, the proportion of mouth cancers attributed to smokeless tobacco exceeds 80%. The study emphasizes the need for improved access to tobacco cessation services, especially in high-risk regions, to mitigate the rising burden of tobacco-related cancers.
Looking ahead, the researchers advocate for targeted prevention strategies and enhanced support for tobacco cessation programs. They stress that addressing tobacco use is crucial for reducing cancer rates and improving health outcomes across the country, especially among vulnerable populations. The study serves as a call to action for health authorities to prioritize tobacco control measures and raise awareness about the dangers of smokeless tobacco.
