Early diagnosis of cancer is often crucial in its treatment, especially with respect to brain tumors.It is therefore important to know the basic symptoms of the early development of a malignant brain tumor in adults and children.
Symptoms of this disease are divided into focal and cerebral.In this tumor in children symptoms appear later than in adults.It is believed that cancer is less common in children than in adults, however, the disease is the second leading cause of child mortality from injuries.Diagnosing brain cancer in a child at an early stage of its development, when it is most successfully treatable, manages only 10% of children.
Symptoms of the disease appear, depending on what part of the brain is subjected to compression of the tumor.Along with the growth in the brain neoplasm blood circulation and increased intracranial pressure, these symptoms are already obshchemozgovye.
first symptoms of a brain tumor
brain cancer at an early stage of its development manifests itself by symptoms s
These symptoms do not always say that a person has brain cancer, since all of these symptoms can also indicate the presence and other diseases.However, you must be wary if you notice a set of two or more of the symptoms.In this case, time is very important to consult a doctor to undergo examination and diagnosis.
focal symptoms of brain tumor
focal symptoms of brain tumors are directly dependent on the human part of the brain, which accounts for the pressure of the growing tumors.For example, if the pressure falls below a department responsible for the patient's vision, the symptoms are manifested as disturbances visual abilities.
to alopecia Symptoms include deterioration in the ability to touch.Patients may lose the ability to sense the location of his body or limbs in space, as well as losing the ability to feel pain, heat, cold or touch.
Another focal symptom is a violation of the motor abilities, such as paresis, consisting in partial violation of motor abilities, or paralysis, in which there is a complete violation of the motor abilities or the entire human body, or of some of its authority.
Just a focal symptoms include seizures caused by irritation of the cerebral cortex.In that case, if the tumor has a compression to the auditory nerve, patients are no longer heard, and if struck by cerebral cortex responsible for speech recognition, the patients perceive environmental sounds as having meaning noise.
addition, depending on the affected area of the brain to focal symptoms include loss of the ability to recognize written text, different subjects, impaired ability to writing and speech, problems with coordination.
brain tumor often accompanied by various autonomic disorders, expressed in fatigue and general weakness of the patients, as well as hormonal disorders and psychomotor impairment, when patients lose their ability to remember information and become more irritable and distracted.
cerebral symptoms of a brain tumor
must say that the cerebral symptoms are caused for the most part the increase in intracranial pressure, as well as the pinching action of the tumor.Moreover, almost all of these symptoms may be characteristic of some other diseases.
most eloquent cerebral symptoms of a brain tumor, which is present in 90% of patients is headache, which usually comes suddenly.Sometimes it is accompanied by vomiting, which may indicate that the tumor is located in the posterior fossa.After vomiting patients usually becomes easier.
Just visible on X-ray changes in the bones of the skull, expanding fontanelles and cranial sutures diverge.In that case, if the tumor has a compressive action on the brain stem, tonic seizures occur.In case of defeat vestibular patients dizziness occurs, which is the result of compression of the cerebellum.
Violation of blood flow or lack of flow in the brain often cause weakness and fatigue patients.
