In malignant tumors, is only removal of the tumor sufficient?

In malignant tumors of the otolaryngology, it is the minimum requirement to remove the entire tumor with some healthy tissue around it. However, this alone may not always be sufficient. Ear, nose and throat tumors are tumors characterized by regional spread via lymphatic routes rather than distant metastases, and in most otolaryngological cancers, the lymph nodes in the neck may need to be cleaned together with the tumor.
