It is generally difficult to determine how many years squamous carcinoma can live in the late stage, and the specific survival time is related to the site, stage and treatment of squamous carcinoma. Squamous carcinoma is a kind of malignant tumor of squamous epithelial origin, and the common sites are nasopharynx, lung, esophagus and cervix, etc. Different sites show different symptoms. Squamous carcinoma of nasopharynx may have symptoms such as nasal bleeding, headache, tinnitus, etc. Early radiotherapy is the main treatment, which has a good prognosis, and some patients can be cured and survive for a long time. Squamous carcinoma of lung may have symptoms such as dyspnea, fever, hemoptysis, etc. Due to the slow growth of squamous carcinoma of lung, the prognosis is generally better. Squamous carcinoma of the cervix often has symptoms such as vaginal bleeding, vaginal fluid, leukorrhea and malodor, etc. Most of them can be cured and achieve long-term survival after surgery or radiotherapy in early stage. Late stage squamous carcinoma is mainly treated with chemotherapy and radiotherapy, and the treatment effect is poor, and the survival period usually ranges from half a year to several years. Commonly used treatment options for squamous carcinoma include radiotherapy, chemotherapy and surgery, etc. Different treatment options should be adopted according to different sites and conditions. It is suggested that patients with advanced squamous carcinoma should actively cooperate with doctors for treatment, take appropriate activities and pay attention to rest to prolong the survival period and improve the quality of survival.
