Brain Tumor – Types, Symptoms, and Causes

Our own brains are the seat of all we have been. Every thought and action we all perform is an output of our brain. So understandably the thought of an disorder striking the brain can be terrifying.

Brain cancer is a rare but destructive form of cancer accounting for 2% of all cancer cases worldwide. Mind cancer refers to the abnormal development and division of cells inside the brain. Brain tumours can be either benign or cancerous and cancer brain tumours are further split up into primary brain tumours that start in the brain and secondary tumours that will start elsewhere in the body and spread (metastasize) to the brain.

Whether harmless or a malignant tumour can boost the volume of the brain which creates pressure in the tight skull space. The particular bony skull is extremely hard and rigid. Any encroachment in this limited space increases intracranial pressure which could lead to brain damage, coma, and even death.

Types Of Brain Tumours

The very first major classification of types of human brain tumours is benign and cancerous tumours. Benign brain tumours are the least aggressive and slowest developing tumours. They do not have cancerous cells and have a good prognosis after treatment.

Malignant or cancerous brain tumours arise from brain cells, supportive cells, and other tissue found in and round the brain. These are high-grade tumours. Grading for tumours involves rating a rise on a scale of 1 to 4 with low-grade scores being one and 2, and 3 plus 4 are high grade. Benign tumours are low grade which is slow growing, contained, less likely to distribute, and unlikely to return after elimination. On the other hand, malignant or cancerous tumours are high grade which means they are fast growing, spread to surrounding tissues, and are more likely to return after removal.

Cancerous tumours are further divided into primary and secondary tumours.

Primary cancerous tumours originate inside the brain itself while secondary tumours are a result of metastasis from tumours in other organ systems, commonly from the lungs.

Primary tumours are rarer and the most common types of primary human brain tumours are gliomas and meningiomas. Gliomas affect the glial cells which are supportive cells in the brain that offer nourishment and structural support to neurons. Gliomas account for 50% of primary brain tumours.

Symptoms Of Brain Tumours

The brain is a large and complicated organ. Symptoms of brain tumours depend on the size, type, and location of a tumour. Some common signs and symptoms are:

Headaches, typically worse each morning and progressively worsening over time.
Chronic nausea
Persistent vomiting
Modern body weakness
Unexplained weight reduction
Behavioural or mood changes
Eyesight problems
Confusion and memory impairment
Specific symptoms depend on the size of the tumour and its location. Based on this particular, some of the signs and symptoms that may be noticed are usually:
Personality changes, less inhibition, poor judgement, etc . in frontal lobe tumours
Language difficulties, poor memory space, and hearing problems in temporary lobe tumours
Sensory disturbances, modern muscle weakness, etc . In parietal lobe tumours
Visual disturbances or even loss of vision in occipital lobe tumours.
Loss of balance and dexterity in cerebellar tumours.
Changes within respiration, blood pressure, and heartbeat in brain stem tumours
