A brain tumor refers to an abnormal growth of cells within the brain. It is characterized by the formation of an intricate mass of cells that may either originate from the brain itself or spread from other parts of the body, known as primary and secondary brain tumors respectively. Tumors may be benign (non-cancerous) or malignant (cancerous).
When a brain tumor grows, it can exert pressure on vital areas of the brain, causing various neurological symptoms including headaches, seizures, changes in behavior, cognitive impairments, and problems with coordination or balance. However, the manifestation of symptoms depends on the location, size, and type of tumor.
Primary brain tumors, which originate within the brain itself, can arise from different types of cells including glial cells, neurons, or meninges. Meningiomas, gliomas, and pituitary adenomas are some common types of primary brain tumors.
Secondary brain tumors, also referred to as metastatic brain tumors, are cancers that have extended to the brain from other parts of the body, usually through the bloodstream or lymphatic system. These tumors frequently occur in individuals with a history of cancer, such as lung, breast, or skin cancer.
Diagnosis of brain tumors may involve imaging techniques like magnetic resonance imaging (MRI) or computed tomography (CT) scans, followed by a biopsy for accurate identification of the tumor type. Treatment options for brain tumors encompass surgical removal, radiation therapy, chemotherapy, targeted drug therapy, or a combination of these methods, depending on the tumor's characteristics, location, and the patient's overall health.
Brain tumors can have a significant impact on a person's quality of life and may necessitate ongoing medical care, support from a multidisciplinary team, and rehabilitation services in order to manage symptoms and facilitate recovery
