The possibility of carrying a tumor means the possibility of surviving with a tumor. Survival with tumor means that patients with malignant tumors in the middle and late stages may not be able to completely remove the cancerous foci, and the patients carry the tumor cells to live and work; in addition, patients with benign tumors may not remove the tumors, and survive with tumors. For patients with malignant tumors in the middle and late stages, the tumor foci in their bodies often have multiple metastases, and it is difficult to completely remove the tumor foci. At this time, the tumor foci can be better controlled by means of radiotherapy, chemotherapy, etc., so that the tumor cells are in the state of quiescence or dormancy, so that the patients are still able to carry on the general life and work, and such a state is called survival with tumors. For some patients with benign tumors, since the tumor will not invade the surrounding tissues or metastasize to other organs or tissues, and will not affect the normal physiological functions of the patients, they can also survive with tumor.
