Tumor confirmed the basis for

Pathological examination is the most accurate diagnosis of the tumor the most reliable methods. It is made of the sick organ secretions smear or remove the lesions directly into slices or small organizations, Indian films, placed under a microscope to observe the cell morphology, structure, etc., to determine the nature of the tumor.
Histopathological pathology is usually divided into two major parts and cell pathology. Pathological diagnosis can not only determine the tumor's benign or malignant prognosis, but more importantly to provide a reliable basis for treatment.

However, pathological diagnosis, also have limitations. Their biopsy specimens, giant body biopsy material, and random checks are ultimately in the light microscope to see only a very small portion of lesions, and sometimes can not replace the entire lesion. In addition the reliability of pathological diagnosis and pathological specimens are also selected. In particular the reliability of cytopathology and histopathology is still a gap compared to, and sometimes there are false-negative results. Clinical diagnosis and pathological diagnosis does not match, the pathological diagnosis should be reviewed, if the pathological diagnosis of the exact accurate, may wish to consider whether the selection of pathology specimens properly. If necessary, to be based on many occasions, so once again pathological diagnosis. In order to avoid misdiagnosis, delaying medical treatment time.

Tumor biochemical, immunological and diagnostic imaging although a great deal of development, but to determine the nature of the tumor is still rely largely on the pathological diagnosis.

A lot of patients that do, such as advanced inspection ct, pet or mri, such as cancer can be confirmed, which is not accurate
