BRAIN TUMOR
PATHOPHYSIOLOGY
- As radiation exposure continues, changes become irreversible causing DNA gene mutation
- inactivation of tumour suppressor genes and activation of oncogenes
- As adaptive mechanism, changes in cell morphology occur
- Uncontrolled cell division and decreased apoptosis
- Irritation and damage to cell structure
- Hyperplasia of brain cell giving rise to a brain tumour.
- Due to causes like chemicals and radiation exposure
NURSING MANAGEMENT
- Suggest smaller more frequent meals
- Provide pain relief measures
- Suggest foods that are well tolerated by the patient
