How Are Brain Tumors Diagnosed? Expert Opinion from a Neurologist in Faridabad
A brain tumor diagnosis is one of the most challenging and life-changing moments a person and their family can face. Whether benign or malignant, timely and accurate diagnosis of brain tumors is the key to effective treatment and recovery. But how exactly are brain tumors detected and diagnosed?
We spoke with Dr. Kunal Bahrani, best Doctor for Brain Tumor in Faridabad, who specializes in the evaluation and treatment of brain tumors. With years of experience and a patient-centric approach, Dr. Bahrani shares deep insights into the diagnostic journey, what symptoms to look out for, and how advanced tools are transforming patient outcomes.
What is a Brain Tumor?
A brain tumor is an abnormal growth of cells within or around the brain. These can be:
- Primary brain tumors, which originate in the brain, or
- Secondary (metastatic) brain tumors, which spread to the brain from other parts of the body.
Tumors can be benign (non-cancerous) or malignant (cancerous), and their effects vary based on location, size, and growth rate.
Common Symptoms of Brain Tumors
While symptoms vary from person to person, the most common signs that may indicate the presence of a brain tumor include:
- Persistent or severe headaches (especially worse in the morning)
- Seizures or convulsions
- Sudden vision or speech changes
- Loss of balance or coordination
- Nausea or vomiting not related to food
- Personality or behavioral changes
- Memory issues or confusion
- Weakness or numbness in limbs
Dr. Bahrani emphasizes:
“Patients often ignore headaches or blurry vision. But if symptoms persist or are accompanied by neurological signs, timely consultation with a neurologist is essential.”
Step-by-Step: How Are Brain Tumors Diagnosed?
- Clinical History & Neurological Examination
Diagnosis begins with a detailed medical history. Dr. Bahrani carefully assesses:
- Duration and severity of symptoms
- Any previous neurological issues or family history
- Associated signs like seizures, weakness, or cognitive difficulties
A neurological examination follows to evaluate reflexes, coordination, muscle strength, eye movements, and mental status.
“A thorough clinical exam helps us localize the affected area of the brain and determine the next steps,” explains Dr. Bahrani.
- Imaging Tests
Once a brain tumor is suspected, the most critical diagnostic tool is brain imaging.
- a) MRI (Magnetic Resonance Imaging)
MRI is the gold standard for detecting brain tumors. It provides detailed images of brain tissue and helps locate the size, shape, and type of tumor.
“Contrast-enhanced MRI gives us a high-definition look at the tumor’s position and interaction with surrounding tissues,” adds Dr. Bahrani.
- b) CT Scan (Computed Tomography)
CT scans are useful when an MRI isn’t available or in emergency cases. It’s quicker and good at detecting bleeding or calcified tumors.
- c) Functional MRI or MR Spectroscopy
In certain cases, these advanced techniques help assess tumor activity, brain function, or detect chemical abnormalities in the brain tissue.
- Biopsy or Surgical Sampling
To confirm whether a tumor is benign or malignant, a biopsy may be necessary. This involves taking a small tissue sample from the tumor for laboratory testing.
There are two main types:
- Stereotactic (needle) biopsy: Done with imaging guidance, typically for deep or inoperable tumors.
- Surgical biopsy: Performed during surgery if the tumor is being removed.
The biopsy helps pathologists determine the tumor type, grade, and aggressiveness, which is essential for planning treatment.
- Other Diagnostic Tools
- Lumbar puncture (spinal tap) may be done to examine cerebrospinal fluid in rare cases.
- PET scans help detect whether the tumor is active or if it has spread.
- Blood tests may be used to rule out infections or inflammation mimicking brain tumor symptoms.
Importance of Early Diagnosis
Early detection significantly increases treatment success and survival rates. According to Dr. Bahrani:
“Many patients delay seeing a specialist. But early imaging and diagnosis not only guide treatment—it can help save lives and preserve brain function.”
Treatment Options After Diagnosis
Once diagnosed, brain tumor treatment depends on the tumor’s:
- Location and size
- Grade (how aggressive it is)
- Whether it’s benign or malignant
- Patient’s age and overall health
Treatment options include:
- Surgery (complete or partial removal)
- Radiation therapy
- Chemotherapy
- Targeted drug therapy
- Steroids to reduce brain swelling
- Rehabilitation for speech, mobility, and cognitive function
“We build a customized treatment plan for every patient. Multidisciplinary care involving neurosurgeons, radiologists, oncologists, and rehab specialists gives the best outcomes,” shares Dr. Bahrani.
