tests
	Take your child to the doctor. The doctor should listen carefully to your description of your child's behaviour and ask you pertinent questions. If symptoms warrant, vision and other tests should be performed. The tumour probably will not be felt. The doctor should order tests: MRI CT scan Both of these tests are expensive, and therefore doctors will likely not order them until they rule out all other possibilities. As a parent, you may need to be quite insistent that they be performed. Any brain tumour will show up on an MRI; the CT scan misses some tumours.
