Brain Tumour : A brain tumor is an abnormal growth of cells within the brain or the central nervous system. Tumors can be either benign (non-cancerous) or malignant (cancerous), and they vary widely in their rate of growth and potential impact on brain function. Symptoms of a brain tumor depend on the tumor's size, location, and rate of growth and may include headaches, seizures, cognitive changes, balance problems, and sensory or motor deficits. Diagnosis typically involves imaging techniques like MRI or CT scans, followed by a biopsy if necessary. Treatment options may include surgery, radiation therapy, chemotherapy, or targeted therapy, depending on the type, location, and stage of the tumor. Early detection and treatment are crucial in managing the condition and improving the patient's prognosis.
