Regular exposure to smokeless tobacco, such as snuffs, may induce the formation of cancerous cells and tumors in the head and neck region of the body.
This meta-analysis investigated the smokeless tobacco-head and neck cancer (HNC) connection hypothesis. Data from 11 studies were included in this meta-analysis.
Researchers found out that imbibing the habit of chewing tobacco and using snuff heightened the risk of developing head and neck cancer, particularly oral cancer, in men and women. This study offered additional insight into the contribution of smokeless tobacco to the development of head and neck cancer.
