The most of the part of the brain is separated from the rest of the body by a barrier among the blood and the brain known as the blood-brain barrier. this barrier exerts a restrictive control as to which substances can pass through. many tracers that reach tumors inside the body very easily would only reach the brain tumors once this barrier gets disrupted. The extent of the disruption of this barrier can be detechted by a magnetic resonance imaging scan or a computed tomography. This extent is hence regarded as the main feature in the direction of the diagnosis of the brain type of cancer to detect the mlignnt gliomas meningiomas and the brain metastases.
Diagnosis of Brain Tumor In Adults
obstruction of the passage of the cerebro-spinal fluid from the brain may occur or swelling may take place as the early sign of intra carnial pressure tht translates clinically into head aches or vomiting and an altered state of consciousness. in the childrens the changes to the diameter of the skull and the bulging of the fortanelles my evenm occur. though any specific type of sign or any sort of clinical symptom for brain tumors is not present but still the presence of a pile of symptoms and a shortage of corelated clinical indications of the infections that occur or the other such causes can prove to be an indicator to diagnose or investigate the possibility of an intracranial neoplasm in this direction to detect the infections or the other causes , if any. The tumors of brain have the similar characteristics and difficulties when the turs comes to diagnose and to perform the therapy with the tumors located in any other part of the body. in some of the cases thy produce tissues specific to the condition that follow closely to the properties of the part or the organ they are located in.
the process of the diagnosis often begins with an interrogation of the individual to get a clear view of his medical antescedents and current signs of his disease. A clinical or a lab investigation may serve to take out the infections if any as the cause of the signs and symptoms in that patient.
The way to examine in this stage may be followed up with otolaryngological or electrophysiological examination of that particular patient. or to examine his or her eyes at this particular stage. the usage of E.C.G. often plays a role in the direction of the diagnosis of the brain tumors.
