Throat cancer is a relatively common ENT disease. Some throat cancer patients may experience weight loss, mainly in the middle and late stages of the disease. This is because these patients generally have a more severe condition, possibly leading to insufficient nutrition. Additionally, throat cancer might affect normal swallowing, thus further accentuating weight loss. Early stage throat cancer, generally, does not lead to significant weight loss. For middle and late-stage patients, comprehensive treatment plans including surgery, radiation therapy, and chemotherapy need to be considered. After treatment, long-term and regular follow-up exams are necessary to monitor the treatment effects. Overall, the earlier the detection and the more timely the treatment, the better the outcomes.
