Cerebral tumor: Symptoms, Cause, Diagnosis, Risk factors

Introduction

The cerebral tumor is a mass or neoplasm, develop of unnecessary abnormal cells in the cerebrum. 

Various kinds of cerebral tumors exist. Some brain tumors are noncancerous (favorable or benign), and some cerebrum tumors are harmful (threatening or malignant). Cerebrum tumors can start in your brain (essential mind tumors), or malignancy can start in different pieces of your body and spread to your cerebrum. 

How quickly it will grow, depends on the nervous system in the body.

Cerebral tumor

Etiology / Causation

Causes are not dependent on age, any age group can be affected by this kind of tumor. Also, sex is no bar.
The main thing is, some uncommon risk factors are responsible to grow this disease. Causation is mainly unknown.



Classification
  1. Tumor of the brain substance such as glioblastomas, astrocytoma, neuroblastoma.
  2. Tumor arising from the meninges meningioma, Fibro blastoma, Reticulum cell sarcoma.
  3. Tumor arising from the nerve neurofibroma.
  4. Secondary carcinoma and sarcoma.
  5. Tumors arising from blood vessels like Angioma.
  6. Tumor arising from hypophysis or its stalk.
  7. Infective granuloma.
  8. Parasitic and other cysts e.g. Cysticercosis cerebral.


Symptoms / Signs
The onset is usually gradual.
Symptoms due to local involvement of cerebral structures.


If the frontal lobe is involved
  1. Progressive dementia
  2. Loss of social sense
  3. Generalized convulsion
  4. Grasp reflex, anosmia

If the parietal lobe is involved
  1. Partial disorientation
  2. Apraxia, agnosia
  3. Sensory inattention or perpetual rivalry
  4. Receptive aphasia
  5. Sensory type of Jacksonian epilepsy

If the temporal lobe is involved
  1. Visual hallucinations and disturbances
  2. Dreamy states
  3. Automatic behavior
  4. Temporary upsets of memory
  5. Aphonia

If the occipital lobe is involved
  1. Crude visual hallucinations (flashing of light etc.)
  2. Contralateral homonymous hemianopia
  3. Symptoms of increased intracranial tension
  4. Headache: Appearing in the early morning or during stooping etc. may be continuous or intermittent
  5. Vomiting: Projectile, occurring at the height of headache not preceded by nausea
  6. Papilledema: Most constant feature and depends upon the degree of intracranial pressure. The whole margin of the optic disc becomes blurred, it becomes pinkish and venous engorgement is also seen, it causes secondary optic atrophy
  7. Mental drowsiness: Insomnia is usually rare
  8. Diplopia: May develop
  9. Pulse and respiration: Bradycardia, Respiration slow and shallow (here may be Cheyne stokes respiration)
  10. Symptomatic epilepsy: Generalized convulsions- May be seen in some cases due to raised intracranial pressure.


Pathophysiology

Age: Embryonal tumors of the cerebrum and different organs (cerebellar medulloblastoma, adrenal neuroblastoma, happen overwhelmingly in kids. Neurogenesis and neuronal movement in the frontal cortex are generally finished by mid-gestation, yet in the cerebellum, they proceed for the primary year of life. The creation of glial cells is extremely dynamic in adolescence. The energetic cell division that is related to these cycles allows the opportunity for new quality imperfections to arise and for acquired ones to be exposed. The cerebellum is the most cell part of the CNS (granular neurons dwarf any remaining neurons in the mind together) and takes the longest to create. It is no incident that it is the most continuous site of BT in youngsters. 

Radiation: An expanded occurrence of BT, particularly meningioma, has been accounted for in patients who have gotten radiation to the head (even low-portion radiation) for an assortment of reasons. Youngsters with ALL who have been treated with craniospinal radiation are at high danger for creating meningioma and gliomas. These tumors arise numerous years after radiation has been given and have all the earmarks of being on the ascent. 

Synthetic Carcinogens: An assortment of substances can incite mesenchymal and glial CNS tumors in creatures by direct intracerebral vaccination and by the oral and parenteral organization. The strongest neuro-carcinogens in exploratory creatures are nitroso compounds (NOCs). NOCs are available in food varieties (restored meats, fish, and vegetables), beautifying agents, elastic items, even in lager and water, and are likewise blended in the mouth, stomach, and bladder by nitration of amines and amides in the eating routine. Given their universal nature, almost certainly, they are likewise engaged with human BT. 

Immunosuppression: Cerebral lymphoma, for the most part, B-cell, is incessant in patients with AIDS, renal transfers, innate immunodeficiency conditions, and other immunosuppressed states. The finding of EBV DNA proposes that a portion of these tumors emerge from EBV-contaminated B-cells.



Risk factors

In the vast majority with essential cerebral tumors, the reason for the tumor isn't clear. However, specialists have recognized a few factors that may expand your danger of a cerebrum tumor. 
Some risk factors are:

Openness to radiation. Individuals who have been presented with a sort of radiation called ionizing radiation have an expanded danger of cerebral tumor. Instances of ionizing radiation incorporate radiation treatment used to treat disease and radiation openness brought about by nuclear bombs. 
Family background of cerebral tumors. A little segment of cerebrum tumors happens in individuals with a family background of cerebral tumors or a family background of hereditary disorder that expansion the danger of cerebrum tumors.



Diagnosis / Investigation

Despite the fact that there is no particular or solitary manifestation or sign, the presence of a blend of side effects and the absence of comparing signs of different causes can be a marker for examination towards the chance of a cerebrum tumor. Cerebral tumors have comparative attributes and snags with regards to analysis and treatment with tumors found somewhere else in the body.
Medical case history is very important and case-taking should be done before treating this condition.
Case-taking should help in diagnosis because a cerebral tumor gives many symptoms as the basis of position. And Patients often go to physicians with those symptoms which shows the causal thinking of patients.

X-ray skull: Erosion or thickening of skull bones. Erosion of glenoid processes, internal auditory meatus, or apex of the petrous part of the temporal lobe.
There may be a shift of the pineal body and sometimes intracerebral calcification.

X-ray chest: Any primary lesion may be seen

Cerebral angiography, carotid or vertebral, may sometimes help in diagnosis.

EEG: May help in the diagnosis

Pneumo-encephalography

Fundoscopy

Brain scanning

CSF study.



Treatment

The patient may be subjected or surgery
If the patient is inoperable following medicines can be tried for symptomatic treatment.

Homeopathic medicines

Baryta carb: When tumors in the brain cause symptoms corresponding to this remedy, this should be prescribed. There are sclerotic conditions of the brain with excessive irritation of all the nerves and premature loss of memory.

Belladonna: This is the prime remedy in all cerebral affections. The child bores its head into the pillow with convulsions and stupor, from which he can hardly be aroused.

Calcarea Carb: It is the medicine for encysted tumors.

Conium: Irritability is the characteristic symptom. Tumors are inclined to be hard, the chief remedy for carcinoma.

Hydrastis: Malignant tumors have disappeared with the continued use of this medicine. The symptoms are a jaded look and sallow complexion, low spirits, loss of appetite, constipation
Carcinosis200: should be given once a week.
