Whether and how long a tumor will deteriorate is related to factors such as the benignity or malignancy of the tumor, the specific type of pathology, and the clinical stage. If the tumor is only benign and the change is not obvious for a long time, the chance of deterioration in this case is relatively low, and most patients will not deteriorate. Some precancerous lesions, may also be malignant, but the specific how long can not be unified, should be based on the specific condition and the patient’s own high-risk factors to analyze. The deterioration of malignant tumors is also related to the type of pathology, clinical staging and other factors. Some cancers with relatively low malignant degree, such as papillary thyroid cancer, can also achieve lifelong non-deterioration after receiving standardized surgery and drug treatment. On the other hand, pancreatic cancer has a higher degree of malignancy, and the 5-year survival rate after diagnosis is only about 3%. For the same kind of cancer, the earlier it is detected and treated, the lower the chance of deterioration of its condition and the longer the survival period. It is recommended that patients go to regular hospitals as soon as possible to get a clear diagnosis and receive standardized treatment, so as not to delay the condition.
