Clinically, when you get an imaging report, especially a CT examination, it is often written that MT may be considered. MT is an abbreviation for malignant tumor in medicine, and considering MT is actually considering malignant tumor. The diagnosis of malignancy depends on pathological biopsy, so if MT is considered, pathological biopsy must be done next. If MT is diagnosed by pathological biopsy, the treatment will depend on the condition of each patient and the stage of the tumor, as well as the tumor in different locations, such as malignant tumor of the thyroid, which may have a better prognosis and a longer survival time. In contrast, pancreatic head cancer is often called the king of malignant tumors, which means that the death rate of pancreatic head cancer is very high, and death will occur within a short period of time after discovery. Regarding the treatment of malignant tumors, if the tumor has reached advanced stage with distant metastasis, it may not be suitable for surgical treatment. For patients with early stage tumors, surgery may be more effective. Other tumors are more sensitive to radiotherapy and radiotherapy is preferred.
