Surgery for cancer is one of the most extensive and mutilating surgeries invented for any patient. It basically follows the principles of removal regardless of cost to patient.
Extensive nutilation is the hallmark of nearly all surgeries in Head and neck Cancer.
Does it sort the issue out? Not really
It only helps in stage 1 and 2 That is localised cancer.In all other cases it will lead to opening of tumour and spread locally.
Is there anything that can be done after that ? Not really .The oncosurgeon will refer you for chemotherapy and Radiotherapy .But it will not help in any case(more than 90%).
