Description

A brain tumour is an abnormal cell growth or mass in the brain. There are many distinct types of brain tumours. Some brain tumours are benign, while others are cancerous. Brain cancers can start in the brain, or they can start elsewhere in the body and spread to the brain. The rate at which a brain tumour grows varies substantially. The rate of growth of a brain tumour, as well as its location, defines how it will influence the function of your neurological system.

An intracranial tumour, also known as a brain tumour, is an abnormal mass of tissue in which cells proliferate and reproduce rapidly, appearing unaffected by the processes that normally control normal cells. There are more than 150 different types of brain tumours, but the two most common types are primary and metastatic. Tumors that arise from the brain's tissues or the brain's immediate surrounds are known as primary brain tumours. Glial and non-glial primary tumours are classified as benign or malignant.

Tumors that start elsewhere in the body such as the breast or lungs and spread to the brain through the circulation are known as metastatic brain tumours. Cancerous tumours that have spread to other parts of the body are known as metastatic tumours. Craniopharyngiomas are often benign tumours that are difficult to remove due to their proximity to important brain regions. They almost always require hormone replacement therapy since they develop from a part of the pituitary gland the organ that regulates numerous hormones in the body.

Schwannomas are benign brain tumours that are common in adults. They form along nerves and are made of of cells that ordinarily supply the nerve cells with electrical insulation. Schwannomas frequently displace the remaining normal nerve rather than invading it. The most frequent schwannoma is an acoustic neuroma, which arises from the eighth cranial nerve, also known as the vestibularcochlear nerve, which runs from the brain to the ear. Although these tumours are benign, if they expand and exert pressure on nerves and eventually the brain, they can cause major difficulties and even death. Other possible sites include the spine and, in rare cases, nerves leading to the limbs. The most prevalent glioma is astrocytoma, which accounts for nearly half of all primary brain and spinal cord malignancies.

Conclusion

Astrocytomas arise from astrocytes, which are star-shaped glial cells that make up the brain's supporting tissue. They can form in any section of the brain, although the cerebrum is the most prevalent. Astrocytomas can affect people of any age, but they are more common in adults, particularly middleaged males. The majority of children's brain tumours are astrocytomas in the base of the brain, which are more common in youngsters or younger people. The majority of these tumours in children are low-grade, but the majority in adults are high-grade [1-5].
