A recent study published in BMJ Global Health highlights a significant correlation between alcohol consumption and an increased risk of mouth cancer in India. The research indicates that even low levels of alcohol intake—specifically, 9 grams per day, equivalent to one standard drink—can elevate the risk of buccal mucosa cancer by approximately 50%. The study found that the risk escalates further for individuals who consume locally brewed alcoholic beverages.
Mouth cancer is a growing health concern in India, ranking as the second most prevalent cancer with around 143,759 new cases and 79,979 deaths reported annually. The incidence of this cancer form has been on the rise, particularly affecting the soft tissues of the mouth. The survival rate post-diagnosis remains low, with only 43% of patients surviving five years.
The interplay between alcohol and tobacco use complicates the assessment of individual contributions to cancer risk. The study indicates that the combination of alcohol and chewing tobacco may account for 62% of mouth cancer cases in India. Researchers analyzed data from 1,803 cancer patients and 1,903 controls, gathering information on drinking and tobacco habits.
Findings revealed that those with buccal mucosa cancer tended to consume alcohol in larger quantities and had longer histories of tobacco use compared to the control group. Notably, even minimal alcohol consumption, such as less than 2 grams per day, was associated with increased cancer risk.
The study underscores the potential dangers of unregulated local alcohol production, which may contain harmful substances. Researchers advocate for public health initiatives to address alcohol and tobacco use in order to mitigate the risk of mouth cancer in India.
