The precancerous cells of throat cancer are produced by a thin layer called squamous cells. The cancer in the epithelium of these cells is called squamous cell cancer and the precancerous condition is called dysplasia. The dysplasia usually does not develop in to actual cancer and goes away on itself if the causative factors (smoking) are removed. So if you smoke, use tobacco or drink alcohol then stop all these and keep in touch with your oncologist. For more details, visit Throat cancer.
