Cancer is the cancer-causing factors in the role of cells, genes are changed, lost control on the growth of normal, leading to abnormal monoclonal proliferation and the formation of a new life. This new form of biological constant local mass, hence the name. According to the tumor's biological characteristics and different dangers on the body, benign and malignant tumors can be divided into two categories. The former slow growth, and the surrounding tissue boundaries clear, the transfer does not occur, there is little risk to human health.

Cancer diagnostic methods 3. Endoscopic examination including bronchoscopy, gastroscopy, colonoscopy, laparoscopy, endoscopy and other projects bladder.
Tumors Mode 4. Pathologic examination of tumor cells including pathological diagnosis, diagnostic pathology, immunohistochemistry and molecular biology inspection technology.
