Brain cancer occurs when the cells in the brain start dividing without any control. Cancer may start in the brain (primary cancer) or spread to the brain from another organ (secondary or metastatic cancer). Symptoms of brain cancer include nausea and vomiting, difficulty speaking, poor balance and coordination, memory problems, and headache.
The techniques for diagnosing brain and nervous system tumors include neurological evaluation, head CT scan, brain MRI, biopsy (image-guided), and PET scan.
The patients may progressively restore brain function after tumor removal. However, during this process, they may need help speaking, thinking, seeing, and moving. Therefore, they are recommended to undergo speech, physical, and occupational therapy after brain tumor treatment.
