At present, there is no clinical data indicating how long the oropharyngeal cancer with lymph node metastasis can live. Generally speaking, patients can live from half a year to five years, but due to the different conditions of individuals, it is impossible to make a generalization. Oropharyngeal cancer is a cancer that occurs in the mucosa of oropharynx, which can occur in the root of tongue, tonsils, ventral side of soft palate, posterior wall of pharynx and other parts. The overall prognosis of oropharyngeal cancer is poor, and it is prone to lymph node metastasis or distant metastasis, mainly through the pharyngeal or submandibular lymph nodes to the deep upper cervical lymph nodes, and the larger the lesion, the higher the metastasis. If oropharyngeal cancer with lymph node metastasis has a large metastatic area, the condition is relatively serious and the survival time is short, which may be only about half a year. However, if oropharyngeal cancer with lymph node metastasis is less and the condition is relatively mild, the survival time is relatively long, and after standardized treatment, the patient can live for about five years, and some patients with better therapeutic effect can even live for a longer period of time, so it is not possible to make a generalization. Some patients have better curative effect and can even live longer, so it is impossible to generalize. Once diagnosed, patients with oropharyngeal cancer with lymph node metastasis need to actively cooperate with doctors to take relevant treatment measures, so as to avoid delaying their condition.
