Small cell tumors are not treated.

Small cell tumor is a pathological type of malignant tumor. Small cell tumor can be found in esophagus, lung, cervix and other parts. Small cell tumor is a highly malignant tumor. Most of its cells are primitive cells and are prone to distant metastasis. However, small cell tumor is generally very sensitive to radiotherapy and chemotherapy. After radiotherapy and chemotherapy, the tumor can regress rapidly and the symptoms can be significantly alleviated. Therefore, for small cell tumors, if the stage can be removed early, surgery should be performed as much as possible, followed by radiotherapy and chemotherapy; for patients who cannot be surgically removed, radiotherapy and chemotherapy should be given priority to.
