Nervous system tumors, also known as brain tumors or central nervous system tumors, refer to abnormal and uncontrolled growths of cells within the brain or spinal cord. These tumors can be either benign (non-cancerous) or malignant (cancerous).
The nervous system is a complex network of nerve cells and tissues that carry and coordinate signals between different parts of the body. Tumors that develop within this system can disrupt the normal functioning of the nerves, leading to various neurological symptoms depending on their size, location, and aggressiveness.
Benign nervous system tumors tend to grow slowly and do not invade surrounding tissues or spread to other parts of the body. However, they can still cause problems by compressing nearby structures and creating pressure within the skull, leading to symptoms such as headaches, seizures, changes in cognitive function, changes in behavior, or loss of coordination.
Malignant nervous system tumors, on the other hand, are cancerous growths that have the potential to invade nearby tissues and spread throughout the central nervous system or to other parts of the body through the bloodstream. These tumors often grow rapidly, exerting pressure on surrounding structures and causing more severe symptoms such as progressive neurological deficits, severe headaches, nausea, vomiting, seizures, and cognitive impairments.
Treatment options for nervous system tumors may include surgical removal, radiation therapy, chemotherapy, targeted drug therapy, or a combination of these approaches. The choice of treatment depends on factors such as tumor type, size, location, and the overall health of the patient. Regular monitoring and follow-up care are often necessary to assess the tumor's response to treatment and manage any potential complications or recurrence.
