Reverse smoking of chuttas seems to have no significance for the development of cancer of the hypopharynx, esophagus, larynx and nasopharynx. The conventional chutta smoker runs a slight risk of developing hypopharyngeal cancer. Other smoking and chewing habits do not seem to play any role in our area as these habits are very uncommon.
反向吸chuttas似乎对下咽癌、食管癌、喉癌和鼻咽癌的发生没有影响。传统的chutta吸烟者患下咽癌的风险较小。其他吸烟和咀嚼习惯在我们地区似乎不起任何作用，因为这些习惯非常罕见。 （注：“chutta”可能是某种特定的烟草制品或方言词汇，这里保留原文未翻译）
