JAPAN 2 Lecture Notes - Lecture 4: Radiation Therapy, Neuroglia, Diplopia
Document Summary
A mass of cells growing independently of the body: they are either malignant-cancerous or benign- harmless. Infiltrating: no clear cut-border, difficult to remove fully, any tissue cell left after surgery will continue to grow. Infiltrating tumour: developed from glial cells, grow rapidly. Metastatic tumours grow from infiltrating cells somewhere in the body and are then carried to the brain via blood streams: metastasis: transfer of disease from one organ to another. Benign-harmless border between tumour cells and surrounding tissue: origins may be lung cancer small survival rate, tumour grows within own membrane. Encapsulated: can be easily cut out, easy to see on ct scan. Treatment: mostly benign and encapsulated, headache and vomiting, slowing of heart rate, functional impairment, double vision, radiation therapy: Some tumours are sensitive/ effective to radiation. Most successful when early diagnosed: chemotherapy: Involves intake of a drug that causes the cells to rapidly divide and die. They target all dividing cells side effects: hair- loss.
