What is required for diagnosis of brain tumor?
The diagnosis of brain tumor is usually performed after a neurological test, imaging tests and biopsy if necessary. Display tests include magnetic resonance imaging (MRI), computed tomography (CT) and positron emission tomography (PET). Biopsy is often performed as part of the tumor removal operation, but can also be done with a needle. The removed tissue is then analyzed to see if the cancer is cancer or benign. In some cases, the doctor may also order further testing to determine whether the patient has cancer in another area of his body, which is a source of brain tumor.
The initial brain tumor symptoms may vary considerably depending on the size of the tumor and the affected part of the brain. The brain tumor is often suspicious when the patient has headaches that gradually deteriorate, are very serious and always in the same place. These headaches usually cause vomiting and blurred vision. Other characters include gradual loss of movement in the armI or leg, difficulty with balance, and speech problems. Some patients may also experience personality changes, confusion and seizures. The diagnosis of brain tumor is a multi -stage process that begins with a neurological test. It is a physical test that usually controls balance, vision and coordination and reflexes. A patient who has problems in one or more of these areas may have a tumor affecting the related part of the brain.
If the patient shows some signs of brain tumor and has problems during the neurological test, the diagnosis of the tumor brain requires diagnostic testing. Display tests help doctors to see inside the patient's head and determine whether there is matter or mass in the brain. The most common imaging test for the diagnosis of brain tumor is MRI, sometimes administered with contrast or injection dye. MRI is a certificate that uses a magnetic field to create pictures of the body and the energy of the radio wave. It causes pain, althoughSome patients may experience a response to dye or symptoms caused by anxiety.
In addition to MRI, the doctor may order CT or PET scanning when diagnosing the brain tumor. CT scan creates cross -sectional images of soft tissues combinations of X -ray -view series. This type of scan exposes the patient to much greater radiation than a normal X -ray, but many doctors believe that the advantage outweighs any possible risk. PET scanning uses radioactive material to show how organ like the brain works.
If the doctor suspects that the patient's brain tumor is actually the result of cancer somewhere else in the body, further testing can be ordered. Such testing may include imaging tests and blood tests. For example, CT scanning can be ordered to look for cancer in the lungs that could spread to the brain.
Diag brain cancer is usually confirmed after biopsy or when collecting and testing the tissue sample. Operation is usually performed to remove any materialsy found in imaging tests that is later tested to see if it is cancerous or not. The alternative to surgical procedure involves the use of a stereotactic needle inserted by a small hole drilled into the skull. CT and MRI scan controls a doctor when it uses a needle to remove the sample. This method is less invasive than brain surgery.
Once the brain tumor diagnosis is made, treatment depends on many factors, including the size and location of the tumor and the patient's health. If possible, surgery is performed to remove the tumor. Other possibilities include radiation therapy, chemotherapy and radiosurgery. Targeted drug treatment is another option. In some cases, rehabilitation, such as speech and physical therapy, may be an essential part of recovery.
