The stage at which the cancer presents itself affects the type of definitive treatment, chance of cure, recurrence of cancer and survival rate of the patient. Generally the patient presents very late due to the lack of definitive symptoms in the early stages of the disease. Nearly three fourths of the patients present in Stage III or later. [22]
