Brain Cancer

Overview
Overview

Brain cancer is a result of cancerous cell growth in the brain. The cancer cells form tumours that can be slow or fast growing depending on the type of the tumours. Primary brain cancer is an overgrowth of cells in the brain that form masses called tumours. This cancer is different from cancers which start in another part of the body and spread to the brain. When this happens, it is called secondary or metastasized brain cancer.

Types of Brain Cancer
Types of Brain Cancer

Brain tumours are named based on where they are located in your brain or upper spine. Tumours are also given a grade, which tells you how fast it is expected to grow. The grades go from 1 to 4, with grade 1 growing the slowest and grade 4 growing the fastest.

Some of the most common types of brain tumours include:

Symptoms of Brain Cancer
Symptoms of Brain Cancer

The symptoms of brain cancer largely depend on the size and location of the tumour. The most common symptoms of brain cancer include the following:

The prognosis for brain cancer is greatly improved by early detection. If you notice any of the above-mentioned symptoms with regularity or think the symptoms might be more significant, consult a doctor immediately for an evaluation.

Causes & Risk Factors of Brain Cancer
Causes & Risk Factors of Brain Cancer

The exact cause of primary brain cancer is not clear. However, studies have shown a link between exposure to high doses of ionizing radiation and an increased risk of brain cancer. 

Medical imaging tests such as CT scans, X-rays, and radiation therapy treatments are the most common sources of ionizing radiation. Other risk factors that might be associated with brain cancer, are:

Secondary brain cancer is more likely to be caused by some types of cancer than others. Cancers that commonly spread or metastasize to the brain include:

Treatment of Brain Cancer
Treatment of Brain Cancer

There are several treatment options for brain cancer. Treatment for primary brain cancer will be different from treatment for cancers that have been metastasized from other sites. The doctor may use one or more treatments depending on the type, size and location of the brain tumour. 

The treatments for brain cancer include:

During the treatment of brain cancer, the doctor removes the tumour and then destroys any remaining cancer cells. Advancements in the treatments are improving brain cancer survival rates, especially in slow-growing tumours.
