A brain tumor is a type of cancer that affects the brain. An intracranial tumour, also called a brain tumour, is an abnormal mass of tissue where cells grow and reproduce out of control, appearing unaffected by the systems that regulate normal cells. Malignant (cancerous) or noncancerous (benign) brain tumours are the two types of cancer. The pressure inside your skull may rise as benign or cancerous tumours enlarge. This has the potential to be fatal and can result in brain damage.
The cause of damaged and dysfunctional genes on a cell's chromosomes, which leads to the development of brain tumours, remains unknown to researchers.
Your brain cells receive new instructions when the DNA in brain cells changes. Your body creates abnormal brain cells that may live longer than average and expand and replicate more quickly than average. If that occurs, the aberrant cell population in your brain quickly outgrows its available area. A person might occasionally be born with changes to one or more of these genes. Environmental factors like exposure to radiation can also bring on brain tumors.
Brain tumour diagnosis can be a challenging process that involves multiple specialists. But occasionally, doctors performing imaging tests for another illness could find a brain tumour as well.
During the primary stage of diagnosis, your healthcare provider might ask you about your symptoms, current medications, family medical history, surgeries, etc. To confirm your condition, they might also conduct a neurological exam to check abnormalities in your balance, mental status, hearing, vision, reflexes, etc.
Brain MRI or CT scan, Biopsy, spinal tap, and other specialized tests are used to diagnose a brain tumour.
Your doctor will design a treatment plan according to your tumor's location and size, age, overall health, etc. The main treatments for a brain tumour are brain surgery, radiation therapy, radiosurgery, brachytherapy, chemotherapy, immunotherapy, targeted therapy, etc.
