Types Of Brain Tumors:-
Tumors can be benign or malignant and can occur in different parts of the brain. It is of two types- primary and metastatic. A primary tumor starts in the brain, whereas a metastatic tumor spreads to the brain from another part of the body. The most common primary brain tumors are:-
- Gliomas (50.4%)
- Meningiomas (20.8%)
- Pituitary adenomas (15%)
- Nerve sheath tumors (8%)
Risk Factors of Brain Tumor
Aside from exposure to vinyl chloride or ionizing Radiation there are no known environmental factors associated with brain tumors.
Mutations and deletions of tumor suppressor can lead to some forms of brain tumors. People with inherited diseases like von hippel-lindau syndrome and neurofibromatosis type 2 are at high risk of developing brain tumors.
Screening Brain Tumor
It Includes Magnetic Resonance Imaging (MRI) And Computed Tomography (CT)-Scans.
Benign brain tumors often show up as hypo dense (darker than brain tissue) mass lesions on cranial CT-scans. On MRI, they appear either hypo- (darker than brain tissue) or isointense (same intensity as brain tissue) on T1-weighted scans, or hyper intense (brighter than brain tissue) on T2-weighted MRI, although the appearance is variable.
Contrast agent uptake can be demonstrated on either CT or MRI-scans in most malignant primary and metastatic brain tumors.
Perifocal edemas, or pressure-areas, or where the brain tissue has been compressed by an invasive process also appears hyper intense on T2-weighted MRI, they might indicate the presence a diffuse neoplasm (unclear outline).
Diagnosis Of Brain Tumor:
Most of the brain is separated from the blood by the blood-brain barrier (BBB) exerting a limiting control for any substance to pass. Hence, most tracers would be able reach brain tumors only with the disruption of the BBB. The disruption of the BBB (blood-brain-barrier) can be detected by a MRI and CT.
Apart from this, the following imaging tests is used to diagnose uterine cancer:
It will followed by clinical and laboratory investigations The use of electroencephalography (EEG) is instrumental in the diagnosis of brain tumors.
Sign and Symptoms of Brain Tumor:-
First headache complaint from person over 50 years old
First migraine attack in person over 40 years old
Headache in person under 6 years old
Severe headaches and very high blood pressure
Headache and fever (with reduced consciousness)
Stiffness of the neck/neurological dysfunction
Headache with signs of elevated intracranial pressure
Focal neurological dysfunction , fits
Loss of consciousness
Early morning vomiting or vomiting unrelated to headache or other illness
Behavioral changes or rapid decline in school results
Brain Tumor Treatment:
When a brain tumor is diagnosed, a specialized team of doctors try to evaluate the treatment options. The treatment options are based on neoplasm type and location.
Surgery
The key intention of surgery is to remove maximum tumor cells possible. However, sometimes the access to the tumor is unfeasible due to which surgery is not allowed.
Radiation Therapy:
The objective of radiation therapy is to kill tumor cells and leave the normal brain tissue undamaged. In external beam radiation therapy, several treatments of standard-dose radiation are applied to the brain.
Stereotactic Radio surgery uses computerized calculations to give radiation at the tumor location while reducing the radiation dose to the nearby brain. Types of radiotherapy for brain cancer are external beam radiation therapy, brachytherapy, and sometimes stereotactic radiosurgery, such as Gamma knife, Cyber-knife or Novalis Tx Radio surgery in more complex cases.
Chemotherapy:
Chemotherapy uses drugs that prevent the growth or division of cancer cells in the body. Patients undergoing chemotherapy are more likely to experience improved survival rates. The decision to undergo chemo is based on the type of tumor, extent of the cancer and the health of the patient.
