Diagnosis of a Brain Tumor
The only way to definitively diagnose a brain tumor is to have a biopsy of the tumor. During a biopsy, a sample of the tumor is taken and examined under a microscope to determine the type of tumor and its exact location. This procedure is usually done under general anesthesia and can be done in several ways, depending on the location of the tumor. Depending on the tumor, an MRI or CT scan may be used to guide the biopsy.
Symptoms of a Brain Tumor
The symptoms of a brain tumor may vary depending on the size, type, and location of the tumor. Common symptoms include headaches, seizures, dizziness, nausea, memory problems, changes in vision, hearing or speech, and difficulty with balance.
Imaging Tests for a Brain Tumor
Imaging tests such as a CT scan or MRI can help to diagnose a brain tumor. These tests can show the size, shape, and location of the tumor. A CT scan or MRI can also help to determine the type of tumor.
Blood Tests for a Brain Tumor
A doctor may order certain blood tests to check for signs of a brain tumor. These tests can measure levels of certain hormones and proteins in the blood that may indicate the presence of a tumor.
Brain Tumor Treatment
Treatment for a brain tumor depends on the type, size, and location of the tumor. Surgery is often the first step in treating a brain tumor, followed by radiation therapy or chemotherapy. In some cases, a combination of treatments may be used.
