Brain Tumor – Types, Symptoms, and Causes

Our brains are the seat of all we are. Brain cancer may be a rare but devastating sort of cancer accounting for two of all cancer cases worldwide. Brain cancer refers to the abnormal growth and division of cells within the brain. Brain tumors are often either benign or cancerous and cancerous brain tumors are further split into primary brain tumors that start within the brain and secondary tumors that start elsewhere within the body and spread (metastasize) to the brain.
Whether benign or a malignant tumor can increase the quantity of the brain which creates pressure within the tight skull space. The bony skull is extremely hard and rigid.

Types Of Brain Tumors
The first major classification of sorts of brain tumors is benign and malignant tumors. Benign brain tumors are the smallest amount aggressive and slowest growing tumors. they are doing not have cancerous cells and have an honest prognosis after treatment.
Malignant or cancerous brain tumors arise from brain cells, supportive cells, and other tissue found in and round the brain. These are high-grade tumors. Grading for tumors involves rating a growth on a scale of 1 to 4 with low-grade scores being 1 and a couple of , and three and 4 are high grade. On the opposite hand, malignant or cancerous tumors are high grade which suggests they’re fast growing, spread to surrounding tissues, and are more likely to return after removal.

Primary cancerous tumors originate within the brain itself while secondary tumors are a results of metastasis from tumors in other organ systems, commonly from the lungs.
Primary tumors are rarer and therefore the commonest sorts of primary brain tumors are gliomas and meningiomas. Gliomas affect the glial cells which are supportive cells within the brain that provide nourishment and structural support to neurons. Gliomas account for 50% of all primary brain tumors.
Symptoms Of Brain Tumors
The brain may be a large and sophisticated organ. Symptoms of brain tumors depend upon the dimensions , type, and site of a tumor. Some common signs and symptoms are:
Headaches, typically worse within the morning and progressively worsening over time.
Persistent nausea
Persistent vomiting
Dizziness
Progressive body weakness
Fatigue
Unexplained weight loss
Behavioral or mood changes
Vision problems
Confusion and memory impairment
Specific symptoms depend upon the dimensions of a tumor and its location. supported this, a number of the signs and symptoms which will be noticed are:
Personality changes, less inhibition, poor judgement, etc. in lobe tumors
Language difficulties, poor memory, and hearing problems in lobe tumors
Sensory disturbances, progressive muscle weakness, etc. In lobe tumors
Visual disturbances or loss of vision in lobe tumors.
Loss of balance and coordination in cerebellar tumors.
Changes in respiration, vital sign , and heartbeat in brain stem tumors
This is a brief summary of tumors within the major regions of the brain. together goes more thorough a spread of symptoms are often found starting from loss of language comprehension to hallucinations.
Cause Of Brain Tumors

The two major factors implicated within the development of brain tumors is genetics and exposure to radiation. Gene mutations, sequence deletions, and loss of tumor suppressor genes are thought to contribute to the explanation for brain tumors. A case history of tumors also increases the danger of developing the conditions. Certain genetic disorders like neurofibromatosis, tuberous sclerosis, and Turner’s syndrome are related to a better risk of developing brain tumors.
Exposure to ionizing radiation has been linked to brain cancer especially in children. Exposure to Vinyl chloride, an industrial chemical want to manufacture PVC, has also been linked to brain cancer.
Other risk factors for brain cancer are:
Age- risk increases with age, apart from some sorts of brain cancer that are more common in children
Previous cancer diagnosis- an individual who has had cancer elsewhere within the body is more in danger of developing brain cancer, especially childhood cancer and blood cancers like leukemia and non-Hodgkin’s lymphoma.

Treatment Of Brain Tumors
The plan of treatment for brain cancer depends on the dimensions , grade, and site of a tumor also as overall patient health. Malignant brain tumors are usually surgically removed. However, surgical resection of a whole tumor might not always be feasible thanks to location or other factors like simple access.
Radiation therapy is another treatment option that’s commonly want to treat brain tumors. Chemotherapy or anti-cancer drugs aren’t always used since the barrier prevents the transport of the many of those drugs into the brain from the bloodstream.
