The survival rate for throat cancer depends on its stage. When diagnosed and treated in its early stage, the 5-year survival rate can be between 80 and 90 percent, states the Oral Cancer Foundation. When throat cancer is in its advanced stages, the 5-year survival rates are 25 to 50 percent, notes the Comprehensive Cancer Center - University of Michigan Health System.
The different stages of throat cancer are from I through IV. The early stages are Stage I and Stage II. In Stage I, the cancer has not spread to lymph nodes and is curable through different treatment options that include surgery and radiation. In Stage II or the intermediate stage, the cancer tumor is larger and may have spread to some lymph nodes. At this stage, treatment can involve surgical removal of cancerous tissues and neck lymph nodes. The removal of the voice box may be necessary.
Stages III and IV are the more advanced stages in which laryngeal cancer has spread to other body organs. At this stage, the disease is incurable, states the National Institutes of Health's MedlinePlus.
