There is no standard answer as to how many years a malignant tumor without proliferation can live at most. There is no fixed figure for how long a malignant tumor without proliferation can live, some patients may live two to three years, some four to five years, and some ten years or even longer. How long a patient can live is decided according to various factors such as the type of cancer, degree of malignancy, physical quality of the patient, and the adoption of treatment plan, and so on. When the malignant tumor does not spread, patients should actively treat it. While the cancer cells have not spread, adopting standardized, suitable and symptomatic treatment plan can achieve better treatment effect and prolong patients’ life. It is recommended that patients whose malignant tumors have not spread go to regular hospitals in time and cooperate with doctors for treatment.
