Pathological staging of tumor is based on the histological examination and imaging examination of the lesions obtained from surgical resection or biopsy, which can guide the treatment plan and judge the prognosis.
After surgery or biopsy, the patient can obtain the lesion tissue, and the histological examination of the lesion tissue can make a more detailed judgment on the infiltration depth of the primary tumor, the invasion range of the surrounding tissues, and the metastasis of the regional lymph nodes, and the tumor staging made by this is the pathological staging, which is more detailed and accurate compared with the clinical staging.
Patients who cannot tolerate surgery or are not suitable for biopsy mostly adopt clinical staging, i.e., the staging made by imaging examination and clinical examination.
Pathological staging of tumors needs to be made by specialists, and patients are advised to communicate with the competent doctors to understand the staging situation according to their actual situation, and not to make guesses or judgments on their own.
