The advanced stage of cancer disease is mainly diagnosed according to clinical symptoms, clinical instruments to judge the stage of tumor development, pathological biopsy and other examination methods to judge the size of tumor and pathological staging.
1. Clinical symptoms: for example, patients with lung cancer can have metastasis in liver, bone and stomach, and patients can have bone pain, discomfort in liver area, etc. If stomach metastasis occurs, patients can have vomiting of blood, nausea and vomiting, blood in stool and other symptoms.
2. Clinical instrument examination: through different diagnostic methods such as CT, ultrasound, pathological biopsy, etc., we can judge the pathological stage of the tumor, the size of the tumor and whether there is any metastasis, etc. If the tumor has vascular infiltration and metastasis to other organs, we can judge that the tumor has already progressed to the advanced stage.
3. Pathological biopsy: Pathological biopsy is the gold standard for cancer diagnosis, which can determine the infiltration of tumor.
Different diseases should be judged specifically, and the most reliable tests are CT, ultrasound and pathological biopsy to confirm the diagnosis. Patients should maintain a positive attitude and choose the appropriate way to judge the progress of the disease and choose the appropriate treatment under the guidance of the doctor.
