What is a brain tumor?
A brain tumor is termed as the mass or collection of abnormal cells present in the brain. The skull is a hard and fixed part. Any type of unwanted growth in such a restricted space will result in problems. Brain tumors are:
- Noncancerous (benign)
- Cancerous (malignant)
The growth of these tumors can pressurize the skull to increase in size. The problem can damage the brain and it is life-threatening also. Brain tumors are categorized by:
In another term, it is called a metastatic brain tumor. Their growth is triggered when cancer cells spread from one part of the brain to another organ like the breast or lung.
These tumors trigger from the brain and their growth is benign.
What are the types of brain tumors?
Primary Brain Tumors
Their growth begins from the brain and developed from the following:
- Nerve cells
- Brain cells
- Meninges (a membrane that surrounds the brain)
Gliomas are tumors that develop from glial cells and the cells are helpful in:
- Clear out the cellular waste
- Dead neurons are broken down
- The central nervous system gets the nutrition
- The central nervous system is supported
Gliomas will develop from glial cells in different types and these begin from:
- Astrocytic Tumors : Begin from the cerebrum
- Oligodendroglial Tumors : Located in the frontal part of the temporal lobes
- Glioblastomas : Begins from the brain tissues which are supported and it is referred to as the most aggressive type
Secondary Brain Tumors
Most brain cancer is made by secondary brain tumors. They begin from one part of the body and then spread to another body part. Some of them are:
- Lung Cancer
- Breast Cancer
- Kidney Cancer
- Skin Cancer
What are the risk factors for a brain tumor?
- Family History
- Chemical Exposure
Signs and symptoms of brain tumor
Symptoms are dependent on the size and location of the tumor. In some cases, the brain tissue is impacted and surrounding tissue will be pressurized. The symptoms are noticeable in this condition. Due to a brain tumor, you are likely to have a headache. It is experienced as:

- Tumor Size
- Tumor Type
- Tumor Location
- General Health
The most commonly performed treatment is surgery. The neuro doctor will aim to remove cancer as much as possible but make sure that the healthy part of the brain is not damaged. It is possible that along with surgery you are suggested to get chemotherapy and radiation therapy. Following neurosurgery, you will be suggested to get speech therapy, physical therapy, and occupational therapy.
