Tobacco use is the leading cause of head and neck cancers in India, including cancers of the mouth, tongue, throat and voice box. Both smoking and smokeless forms, such as gutka, khaini, zarda, paan with tobacco and mawa, damage the lining of the mouth and throat. Areca nut (supari) on its own is also linked to cancer. Quitting at any age lowers the risk over time.
