The Brain cancer is a growth in the intracranial tumors, including brain parenchyma occurs in primary brain tumors and by other parts of the body is transferred to the secondary intracranial brain tumor. Primary brain tumours divided according to their biological characteristics of benign and malignant. Benign brain tumors grow slowly, capsule more complete, no infiltration of the surrounding tissue and differentiated; malignant brain tumors grow faster, no capsule, boundary is not clear, infiltrative growth, poorly differentiated. Both benign and malignant, can squeeze, over normal brain tissue, resulting in intracranial pressure, a threat to human life.
In the systemic malignant tumor, malignant brain tumors account for about 1.5%, eleventh in gastric, lung, liver, columns, esophageal, rectal, breast, colon, pancreas, bladder and nasopharyngeal carcinoma after. Male more than female, sex ratio is 1.12~1.52:1, various types of brain tumours in the sex ratio varies with the age increasing, while the increasing trend. Can be any age of onset, but infants below the age of 2and over 60 years of age or older onset less. Brain tumors in children, a larger proportion, about systemic tumor7%, accounted for all20% brain tumor cases.
In recent years, intracranial tumor incidence rate assumes the trend of escalation, according to statistics, intracranial tumors account for about systemic tumor5%, accounted for childhood tumors and other malignant tumor70%, there will be20-30% to intracranial, due to the expansion of infiltrative growth, in intracranial once according to certain space, regardless of its nature is benign or malignant, it is bound to the elevation of the intracranial pressure, compression of brain tissue, leading to central nervous system damage, endanger patient life.
Intracranial tumors can occur at any age, with20-50is the most common. Children with posterior fossa and midline tumors were more common, mainly medulloblastoma, craniopharyngioma and ependymoma. In adult glioma of the cerebral hemisphere was most common, such as astrocytoma, glioblastoma, ependymoma, followed by meningioma, pituitary adenoma and craniopharyngioma, neurofibroma, cavernous hemangioma, cholesteatoma. The incidence of primary intracranial tumors showed no significant gender differences, male more than female.
Brain tumor treated by traditional Chinese medicine at present mainly used before and after operation, radiotherapy and chemotherapy after adjuvant treatment or not operation and chemotherapy in patients with. Brain tumor treated by traditional Chinese medicine is to control the main tumor progression, metastasis, shrinking the tumor remission of disease and reduce radiotherapy, chemotherapy adverse reactions; achieve the purpose of treatment. The quality of life improve, extend the life of.
