Not all malignant tumors are incurable, some of them can be cured. In fact, as long as malignant tumors are diagnosed in time, most of them can be cured in the early stage of malignant tumors. There are also some malignant tumors, even if they are not necessarily early, such as hematological diseases and lymphomas, which may be found in multiple areas at the same time, such tumors can be cured through chemotherapy and molecular targeted therapy. However, some malignant tumors can be cured very poorly when they reach advanced stages. It is not necessarily that malignant tumors cannot be cured, first of all, we have to distinguish which stage they are in, early stage patients have a chance to be cured.
