Brain cancer can be defined as a tumour or cancerous growth in the brain. It is an uncontrolled increase in cells. There are two main types of tumour. The first one can be defined as a collection of cells that have a prolonged reproduction rate and they often remain separated from the brain. On the other hand, the other one grows vigorously and often spread to other parts of the brain as well.
The exact reason for the brain cancer is still unknown. If cancer originates in a tumour which is inside the brain, then it is known as primary brain cancer. It can spread to other nearby body parts and cause damage to them as well. The other type metastatic brain cancer also known as secondary brain cancer reaches to brain from another body parts, for example: breast cancer, skin cancer, lung cancer or blood cancer cells can form such brain cancer.
Brain cancer symptoms may include:
If the doctor notices one or more symptoms in the patient, he might recommend MRI scans, biopsy to check if the tissue is cancerous or not. Sometimes, lumbar puncture is also done as a diagnostic procedure.
Prevention of brain cancer is not possible as the causes are still widely unknown but regular health checkups can definitely help in determining the presence of cancer at an early stage, thus you will be saving a lot of treatment cost and associated pain and stress in the long run.
