Brain tumors are the most common solid tumor of childhood.
They may develop in a child of any age. Very young children often are not able to complain of these symptoms and thus the delay in diagnosis and appropriate treatment often occurs. Some brain tumors can spread to other parts of the nervous system such as the spinal cord. In addition to images of the head, the spinal fluid may also need to be examined and a Magnetic Resonance Imaging scan, or MRI , of the spine may be obtained. An MRI is a technique for creating pictures of body structures and organs.
