Hi, Thanks for writing in. Throat cancer is to be confirmed after doing detailed clinical assessment and investigations. There are cases where the findings can mimic cancer and are actually a chronic disease and this needs to be confirmed. There are also cancers which can be slow growing and do not kill the patient. It can cause discomfort and morbidity but the patient will survive for years. Also there can be those in who aggressive treatment has been provided by surgery, chemotherapy and radiation in various combinations and this has been able to arrest the cancer progression and stabilize the disease. Since the person has survived beyond the clinical expectation of his doctor, it will help to make a detailed assessment and control the disease as much possible.
