Finding out if someone has a brain tumor can be scary, but doctors have many ways to find answers. They use special tests to see what’s happening inside the brain.
These tests help them know if a tumor is there, how big it is, and what kind it might be. In this guide, you’ll learn about the main medical tests doctors use to diagnose brain tumors, explained in a simple, clear way.
Know the Symptoms
Headaches that get worse over time can be a warning. You may feel dizzy or lose your balance. Blurred vision can also be a clue. Some people feel sick or throw up often. You might forget things more than usual. Changes in mood or behavior can happen.
Trouble speaking or understanding words may appear. Weakness in your arms or legs is also a sign. Seizures can happen, even if you never had them before. If you notice these changes, see a doctor right away.
First Doctor Visit
You should share all your symptoms. Tell them when the problems started. Be honest about your pain and changes. The doctor will check your eyes and balance. They may ask you to walk or lift your arms. You might be asked simple questions to test memory.
These checks help spot brain changes. Your doctor may ask about family health history. If needed, they will order brain scans. You may get a referral to a specialist.
MRI and CT Scans
A CT scan is often the first test done. It uses X-rays to take fast pictures of the brain. This can show bleeding, swelling, or large tumors. An MRI gives even more detail. It uses magnets and radio waves instead of X-rays.
MRI scans can spot small tumors and changes in brain tissue. These tests do not hurt, but you must lie very still. The MRI machine can be loud, but earplugs may help.
Biopsy Basics
A biopsy is a test doctors use to study a brain tumor. They remove a small piece of the tumor. This piece is sent to a lab. Experts look at it under a microscope. The test shows if the tumor is cancer or not. It also tells how fast the tumor might grow.
Some biopsies are done during brain surgery. Others use a needle to take the sample. The doctor chooses the safest method for you. The results help plan the best treatment.
Getting the Results
After tests are done, doctors look at all the results. They study the brain images closely. They compare pictures from both MRI and CT scans. The choice of MRI vs CT scan depends on what they need to see. Sometimes, both are used to get a clearer view.
The biopsy report takes a little more time. Lab experts check the tumor sample carefully. They send the report to your doctor. Then, the doctor explains what the results mean.
