Brain Tumor Diagnosis

Brain Tumor DiagnosisHere's a fact about brain tumors that might surprise you. Less than 1% of people are diagnosed with a malignant brain tumor in their life. Still, many people likely know somebody or have heard of somebody in their life who has a brain tumor. They're scary, but the diagnosis isn't always fatal. 

Receiving a diagnosis of a brain tumor can be a daunting and life-altering experience. It is important to gather as much information as possible to understand the condition. You should also learn about the diagnostic process and the available treatment options.

Your first question might be, "What is a brain tumor diagnosis?" In the article below, you'll find more information on brain tumors.

This article will provide a comprehensive overview of what you need to know about getting diagnosed with a brain tumor. Continue reading to learn more about brain cancer. 

Understanding Brain Tumors

A brain tumor refers to the abnormal growth of cells in the brain. These tumors can be either benign (noncancerous) or malignant (cancerous).

They can originate within the brain (primary tumors) or spread to the brain from other parts of the body (metastatic tumors). Brain tumors can affect various functions of the brain, leading to a wide range of symptoms.

Common Symptoms

The symptoms of a brain tumor can vary depending on its location, size, and type. Common symptoms include persistent headaches, seizures, and vision changes.

You may also experience difficulty speaking or comprehending language and loss of balance. In some cases, people also experience memory problems and personality changes. If you experience any of these symptoms persistently, it is crucial to consult a healthcare professional.

Seeking Medical Attention

If you suspect a brain tumor, the first step is to consult a primary care physician or a neurologist. They will evaluate your medical history, perform a physical examination, and assess your symptoms.

Based on their findings, they may refer you to a neurosurgeon or a neurologist. These are doctors who sometimes specialize in brain tumors and can provide a further evaluation.

Diagnostic Procedures

To diagnose a brain tumor, various imaging tests and procedures are typically employed. These include the following procedures.

Magnetic Resonance Imaging

The magic resonance imaging (MRI) technique uses powerful magnets and radio waves to create detailed images of the brain. These help doctors find a brain tumor if one is present. It is generally advised that all patients who may have a brain tumor get an MRI for brain tumor identification during the diagnostic process.

Computed Tomography Scan 

A computed tomography (CT) scan uses X-rays to create cross-sectional images of the brain. These provide information about the tumor's structure and location. Once the doctor has identified the structure and location of the tumor, they can begin to figure out how to treat it.


In some cases, a tissue sample may be required to determine the tumor type and grade. A biopsy involves the removal of a small piece of tissue for laboratory analysis.

This is usually performed during surgery or with the help of stereotactic techniques. Patients should be prepared for an invasive procedure if they do have a tumor that requires a biopsy. 

Lumbar Puncture

This procedure involves collecting cerebrospinal fluid (CSF) through a needle inserted into the lower back. Analysis of the CSF can provide information about the presence of tumor cells or other abnormalities.


In certain cases, an angiogram may be performed to visualize the blood vessels in the brain. It can help determine the blood supply to the tumor and assist in surgical planning.

Some tumors grow to be so large that they restrict the amount of blood getting to the brain. If the brain is being cut off from getting enough blood, the doctor may need to act quickly. 

Classification and Staging 

Brain tumors are classified based on their cell type, location, and behavior. The World Health Organization (WHO) classification system categorizes brain tumors into different grades. 

These grades range from Grade I (least aggressive) to Grade IV (most aggressive). Staging refers to determining the extent of the tumor's growth and spread, helping to guide treatment decisions.

If you have a Grade I tumor, it is more likely that the doctor will be able to remove it or stop it from growing. The higher the grade, the harder it is for the doctor to prevent the tumor's growth.

Treatment Options 

The treatment of a brain tumor depends on various factors, including tumor type, grade, size, location, and overall health. Treatment options may include the following.

Surgery Options

Surgical removal of the tumor is often the primary treatment modality when feasible. The goal is to remove as much of the tumor as possible while preserving brain function. While surgery can be successful, it is also risky since it involves invasive surgery near the brain.

Radiation Therapy

This treatment utilizes high-energy X-rays or other forms of radiation to kill cancer cells or shrink tumors. It may be employed before or after surgery or as the primary treatment for tumors that are difficult to reach surgically. It can be effective but does have notable side effects.
