It is known as the abnormal brain tumor growth in a group of brain cells. This abnormal growth causes disruption in brain function of the specific area in which it develops and inflames the brain around.
When a brain tumor appears, it is because a group of cells undergoes some changes in their genes that produce an excessive and atypical growth, leading to occupy a new space in the brain, moving, destroying or occupying any part of it that does not It corresponds.
Types of brain tumor
There are different types of brain tumor, but are among the main glioma and astrocytoma. These tumors, according to experts in neurosurgery , stem from structural brain cells and, based on their ability to destroy cells or atypical blood vessels grow, they are given a greater or lesser degree of malignancy.
There are other types of tumors, including meningiomas, non-cerebral type, are their covers or other brain structures but not growing in the cranial cavity, damaging the brain by compression, irritation or blockage of the flow of cerebrospinal fluid. Most of these tumors are benign origin, but the fact that they grow in a closed cavity and thereby increasing intracranial pressure, makes them potentially malignant tumors.
Another type of brain tumor metastasis occurs when malignant tumors elsewhere in the body is developed and implanted in the brain, with rapid growth and aggressive behavior.
Most types of brain tumors have no known cause. There are few clear risk factors, except in very specific cases such prior radiotherapy, hormone treatments and metastasis, among others. There are also very specific subtypes of genetic or embryonic origin.
Brain Tumor Diagnosis
The basic diagnosis of a brain tumor can be done with a CT scan. However, in order to choose the appropriate treatment it is essential to have an MRI of good quality.
Later we must subtipificarlo with taking a biopsy sample or, if possible, their surgical removal and examination of specific pathology.
