The reason why cancer is called incurable is that if cancer is not detected in time, it is easy to develop distant metastasis. If distant metastasis occurs, it is definitely not curable, but can only try to control the tumor and prolong the patient’s life, but eventually the patient will still die because of the development of the tumor, so it is called incurable disease. However, with the development of medical technology and the popularity of medical checkups, some tumors are found to be relatively early, so it is still possible to cure them through surgical resection. Some of them also need adjuvant radiotherapy and chemotherapy after surgery, which can further improve the cure rate of tumor through comprehensive treatment. Therefore, if the tumor is found early, it is not considered incurable and can be treated.
