Throat cancer generally is not contagious. Currently, the most accurate and fundamental etiology of throat cancer is not particularly clear. It may be related to genetic factors or issues with genes, or it could be due to long-term lifestyle habits, such as smoking, drinking alcohol, or exposure to irritating radioactive substances. Overall, from existing medical treatments and research, there is no evidence found of definite contagiousness. Thus, it is not considered an infectious disease, and excessive isolation is not necessary. Regarding treatment, it is primarily surgical-based at the moment, with some patients requiring a combination of radiotherapy or chemotherapy as comprehensive treatment methods. Also, long-term regular follow-ups are needed to monitor the recovery process.
