What is a tumor?

If the tumor is benign, the treatment method should be determined according to the size of the tumor, combined with the patient's age and constitution. If the tumor is malignant, the appropriate treatment plan should be selected according to the comprehensive evaluation of the tumor stage and the patient's physical condition. If the tumor is in the early stage, elective surgery should be selected. If the tumor is too large to be removed immediately, neoadjuvant chemotherapy can be performed. When the tumor shrinks, surgery can be performed again; if it is advanced and the opportunity for surgery is lost, chemotherapy can be selected for treatment.
