Brain tumors are not always cancerous
A brain tumour is a tumour inside the human brain, which is created by an abnormal and uncontrolled cell division. So, if a tumour develops in the brain or spread to other parts of the body, many vital abilities like speech, memory, and movement, might be affected.
Any brain tumour is inherently serious and life-threating because of its offensive and infiltrative character. But, it is not always cancerous or malignant.
Is it Benign or Malignant?
Benign, a brain tumour does not contain any cancer cells. On the other hand, this type of tumour can be dangerous because when it enlarges, it can put pressure on the delicate tissues of the brain. Usually, the benign tumour can be taken out with surgery and in most cases doesn’t grow back.
Malignant type of brain tumour contains cancer cells. These cancer cells might grow slowly or rapidly. Malignant tumours are often life-threatening but only sometimes because this kind of tumour spreads to other parts of the body, in a process called metastasis.
Brain tumours can be primary or metastatic also. Primary brain tumours arise within the brain and there are 100 of its kind, whereas metastatic also known as secondary brain tumours spread from other parts of the body through the bloodstream and enter the brain. The most common cancers that spread to the brain are lung, breast, melanoma, and colon.
The signs and symptoms of a brain tumour vary greatly and depend on the brain tumour's location, size, and rate of growth.
Other general symptoms may include:
- New onset or change in pattern of headaches
- Seizures and headaches that gradually become more frequent and more severe
- Nausea or vomiting
- Blurred vision, double vision or loss of peripheral vision
- Continuing loss of sensation or movement in an arm or a leg
- Speech difficulties
- Personality or behaviour changes
- Hearing problems
Difference between child’s and adult’s brain tumour
There is a difference between child’s brain tumour and an adult’s, as they are found in different places, have different symptoms, and have different tendencies to spread to other parts.
Tumours develop in the cerebral cortex in most adults. The cerebral cortex is the upper area of the brain that has a role in memory, thought, and more, whereas children frequently develop tumours in the brain stem and cerebellum, which is located near the brain stem and affects movement and coordination.
