How is Brain Cancer Detected?

Patients with brain tumors may have symptoms such as headaches, seizures and other neurological problems. Because many of these symptoms are not unique to brain tumors, it is difficult to make a diagnosis without some type of imaging study. Diagnosis often  involves visualization of the brain tumor by a physician using tools such as positron emission tomography-computed tomography (PET-CT), Computed tomography (CT) scan or magnetic resonance imaging (MRI). Once the diagnosis has been made, more tests may be necessary to identify the specific type of tumor and determine the proper treatment for the patient.
