Even low levels of alcohol consumption, combined with factors such as chewing tobacco, can lead to a 50% increase in alcohol intake. oral cancer riskscientists warn in a new study.
Oral cancer is the eleventh most common cancer in the world, with a very high incidence rate high prevalence South Asia, especially India.
However, how to combine the main risk factors Whether it increases a person’s chance of developing cancer remains unclear.
Now, researchers have found that the combined effects of drinking alcohol (even one drink a day) and chewing tobacco (a common practice in South Asia) are particularly severe.
This pairing may be responsible for nearly two-thirds of oral cancer cases in India, scientists found in research published in the journal BMJ Global Health.
The researchers said the strongest link was among those who drank local alcoholic beverages, such as grandson, Bengali, Chuliand Mahua.
For the study, scientists compared data from 1,803 people aged 35 to 54 who were diagnosed with buccal mucosal cancer with data from 1,903 randomly selected people who did not have the disease.
Participants provided information about when they drank, how often they drank, and the types of drinks they drank.
These include 11 international drinks including beer, whiskey, vodka, rum and Breeze beer, as well as 30 locally brewed drinks.
Participants were also asked about their tobacco use, including duration and type.
Among those diagnosed with cancer, 781 reported drinking alcohol, while 1,019 reported not drinking.
In comparison, 481 people in the control group drank alcohol and 1,420 did not.
Researchers found that regular alcohol consumption was strongly linked to an increased risk of cancer, with locally brewed drinks showing the best results.
Scientists have found that drinking even very small amounts of alcohol, such as 2 grams of beer per day, still increases the risk of buccal mucosal cancer.
Research shows that consuming 1 standard drink per day (approximately 9 grams of alcohol per day) is associated with an approximately 50% increased risk of oral cancer.
Researchers warn that exposure to both alcohol and tobacco results in a more than four-fold increase in risk.
They suspect alcohol may change the fat content of the lining of the mouth, making it more permeable and susceptible to cancer-causing chemicals in chewing tobacco products.
Scientists say locally brewed alcohol may pose a greater risk, in part because of its alcohol content and contamination with toxic substances such as methanol and acetaldehyde.
“The market for locally brewed alcohol is unregulated, and some drinks used by participants contain alcohol content as high as 90 percent,” the researchers wrote.
“Overall, our research shows that there is no safe limit to the amount of alcohol you can drink. [buccal mucosa cancer] risk,” they concluded.
