1.Determine personal information When you get the pathological diagnosis report at the first time, please confirm whether the basic information is consistent, including the patient’s name, age, disease site and so on, in order to confirm that the report is the patient’s own report. 2.Understand the nature of the lesion by naming the tumor The nature of the lesion is the most concerned benign or malignant. Generally, according to the biological characteristics of the tumor and its harmfulness to the body, it can be divided into benign, junctional, malignant and cannot be clearly meaningful. Usually, we can distinguish the nature of lesions according to the naming of tumors. Malignant tumors are mostly named as “cancer” or “sarcoma”, such as liver cancer, stomach cancer, bone sarcoma, etc.; while benign tumors are generally named as “tumor”, such as breast fibroadenoma, etc.; a few of them are junctional tumors. A few of them are junctional tumors, which are between benign and malignant in nature, with slow growth or late recurrence, but can metastasize and have low metastasis rate, such as: ovarian junctional plasmacytic cystadenoma; there are also some tumors that we are not clear about benign and malignant, and can only be described with unclear meaning. (Note: Few tumors are named in a special form, such as: leukemia, lymphoma, etc. are also malignant tumors. Therefore, the benignity and malignancy of tumors cannot be distinguished by naming alone, but need to be analyzed with specific clinical conditions). The higher the differentiation, the closer the tumor cells are to normal tissue, and the lower the malignancy (highly differentiated is better than low differentiated). And the grade of tumor can be understood as the difference with normal tissue, the higher the grade, the higher the malignancy (grade III malignancy is greater than grade I).
