A new study published in the International Journal of Cancer has revealed a significant link between the use of smokeless tobacco and hypopharyngeal cancer. The research highlights that products such as chewing tobacco, snuff, and other forms of smokeless tobacco can increase the risk of this type of cancer, which affects the area at the base of the throat.
Dr. Amir Sapkota from the Indian Cancer Center led a comprehensive investigation involving 1,024 patients diagnosed with various head and neck cancers, along with 718 healthy individuals who served as controls. The findings showed a clear association between smokeless tobacco use and hypopharyngeal cancer, but not with laryngeal cancer.
Specifically, the study found that users of nasal inhalers had a 2.85 times higher risk of developing hypopharyngeal cancer, while those using pan, zarda, and gutka had significantly higher risks—3.34, 3.58, and 4.59 times, respectively. These results emphasize the dangers of these products, which are often mistakenly considered safer alternatives to smoking.
The researchers also noted a growing concern about the rising rates of upper respiratory tract cancers in India. This trend is partly attributed to the widespread misconception that smokeless tobacco is less harmful than cigarettes. Additionally, the increasing popularity of these products among young people in North America is influenced by social trends and cultural acceptance.
This study serves as a critical reminder that even without combustion, tobacco use still carries serious health risks. Public awareness and education on the dangers of smokeless tobacco are essential in preventing future health crises.
