The exact cause of brain tumours is not known but factors that have been linked to their development include radiation and chemical exposure and certain genetic conditions. If you have a parent, relative or friend who has had cancer, you may be more likely to develop the disease yourself. This is called secondary cancer.
How tumour are originated and spread?
Cancer can spread throughout your body from the place the original (primary) tumour started. Brain Cancer is the second most common type of solid tumour to affect children, after paediatric leukaemia. Where in your brain a tumour begins is an important factor in whether it is treated with surgery, radiation therapy or chemotherapy, as well as how much time you have left to live with cancer.
