Patients with nasopharyngeal carcinoma should not smoke, as tobacco is a very certain carcinogenic factor. There is a significant correlation between the high incidence of nasopharyngeal carcinoma and long-term smoking. Therefore, if patients do not eliminate carcinogenic factors, nasopharyngeal carcinoma is likely to recur or metastasize after curative surgery or radiotherapy. Additionally, patients with nasopharyngeal carcinoma need to undergo treatment strategies such as surgery, radiotherapy, and chemotherapy. Continuous smoking can affect the effectiveness of these anti-tumor treatments and is detrimental to the patient's recovery. Furthermore, smoking can also lead to other types of malignant tumors. Therefore, it is not advisable for patients with nasopharyngeal carcinoma to smoke. It is also recommended that patients improve other unhealthy lifestyle habits, such as long-term alcohol consumption, a high-fat diet, and the consumption of pickled or fried foods, as these are also causes of high nasopharyngeal carcinoma incidence and should be avoided.
