Brain cancer

Brain cancer's disease overview

What is

brain cancer ? Brain cancer are tumors that develop malignant in the brain, including two main types: primary brain cancer and secondary brain cancer due to metastasis from other places (mainly from the lungs, breasts, ...). Depending on the location and size, brain cancer has symptoms as well as has a dangerous effect on the lives of patients.

Causes of Brain cancer's disease

Causes of brain cancer have not been clearly defined. Brain cancer is not infectious but there are some cases of genetic properties. Some syndrome related to brain cancer:

  • Turcot syndrome: Form many benign polyps in the colon along with primary brain tumors.
  • neurofibromatosis syndrome: called nerve tumors, is a genetic disease associated with neurological disorders that affect the brain, spinal cord, nerves.

    • In addition, patients are exposed to radioactive substances or have a history of radiation therapy in the head of the neck, a history of exposure to toxic chemicals (pesticides, oil and gas, solvent Soluble, rubber chemicals, vinyl plastic ...) also have a higher risk of brain cancer.

    EBV virus infection (Epstein-BARR Virus) and CMV (Cytomegalovirus) increases the risk of brain cancer

    Symptoms of Brain cancer's disease

    The most characteristic brain cancer symptoms are characterized by increased intracranial pressure due to increased tumor volume, increasing volume due to cerebral edema and stagnant of cerebrospinal fluid. There are also symptoms of the tumor.

    Increased intracranial pressure:

  • headache: 80-90% of brain cancer patients have local or whole. Pain caused by tumor pinched the nerves of the brain, the sinuses of the vein causes the cerebral vascular spasm. Pain may be severe or vague of unknown pain. Patients with frequent pain, tendency to increase, take pain relievers. /Li>
  • eaters: edema or atrophy occurs when increased intracranial pressure presses the hinted nerve bundles. The patient appears blurred with a headache and vomiting.
    • brain.

    Symptoms of damage area: Can from mild to severe like a single nerve paralysis, weak limbs, memory loss or vision loss:

  • frontal lobe tumor: Memory decrease or attention is a common symptom in the frontal lobe tumor. Patients may lose smell and atrophy of the optic nerve, which can also lose language if the tumor is behind the frontal lobe
    • Dynamic, reducing sensation, tactile, unable to locate the space position. Can not call the name of the object. If the tumor pinches the common nerve, the patient may collapse the eyelashes and pupils. The intracranial hypertension syndrome often appears early because of compression into the cerebral drain. Li>
  • Pituitary gland: headache, vision loss, sleep disorders. Patients eat a lot, drink a lot, piss a lot. Maybe obese, big toes and fingers or huge status accompanied by genital disability
  • Uye corner cerebellum corner: Tinnitus, dizziness, hearing loss. Patients may numb the face and tongue due to compressed tumor into the wire v.

    • People at risk for Brain cancer's disease

    Brain cancer may appear in all age groups but the lungs most varied in children from 3-12 years old and adult groups from 40-70 years old.

  • People with a history of radioactive exposure or neck radiation therapy
  • People with lung cancer, breast cancer .. have the potential to have metastatic brain cancer < /Li>
  • People with Turcot syndrome, neurofibromatosis syndrome

    • Prevention of Brain cancer's disease

    Currently, there is no specific measures to prevent brain cancer. Patients are recommended to check for checkups when there are signs of suspicion such as headache, vomiting, prolonged nausea or sudden weakness in human being, difficult to speak, visual disorders, hearing ...

    Especially cancer patients should be screened for metastatic brain cancer when symptoms signal.

    Diagnostic measures for Brain cancer's disease

    Diagnosis of brain cancer based on clinical symptoms and the following tests:

  • Computerized tomography: Determine the location, size and level of surrounding invasion, brain edema, increased intracranial pressure. Accurately assess the location and correlation of the tumor with the surrounding groups. The brain takes place
  • PET-CT: Evaluation of brain tumors and other systemic tumors simultaneously. Li>

    Review Stages in brain cancer are not used like other cancer because most of the primary brain cancer is not invasive outside the system. nerve. People use the term I-IV brain cancer to describe the progression of brain cancer:

  • Brain cancer Grade 1: The tumor grows slowly, not spreading can be treated with surgery
  • Brain cancer level 2: Less tumor is likely to grow And spread but more likely to return after treatment. Dead
  • Brain cancer 4: Quickly divided tumor, invasive blood vessels and even dead tissues around the brain. The tumor develops and spreads.

    • Brain cancer's disease treatments

    Treatment of brain cancer includes 3 main methods: surgery, radiation and chemicals.

  • Surgery: The goal is to remove the tumor without causing surrounding organs. However, surgery depends heavily on the location of the shallow or deep tumor, whether the tumor is clear or not, the level of surgeon as well as the equipment. Not all brain tumors can be removed thoroughly. Deep brain tumors, brain, brain body, near large blood vessels, remove very difficult tumors due to near respiratory, cardiovascular and difficult to stop bleeding
    • Cancer remaining after surgery or deep malignant tumors that surgery cannot be performed. Chemicals are acting in cases of fast growing tumors, glioblastoma, Astrocytoma levels and IV. circuit, gene and protein effect (bevacizumab, laborrectinib ..)
