Not true. While smokeless tobacco use, such as chewing tobacco, is a significant risk factor for oral cancer, it is not the only cause. Oral cancer can also occur in individuals who do not use tobacco products. Other risk factors for oral cancer include heavy alcohol consumption, human papillomavirus (HPV) infection, sun exposure (which can increase the risk of lip cancer), poor oral hygiene, and a history of oral diseases or infections. Therefore, while smokeless tobacco use greatly increases the risk, it is not the sole cause of oral cancer.
Only people who chew smokeless tobacco can get oral cancer. true or not true?
