Brain Tumor Symptoms: Early Signs & How to Detect

Are you searching for “What are the symptoms of a brain tumor?" Here are the general signs and symptoms:

• Headache or pressure in the head worsening in the morning
• Frequent severe headaches 
• Nausea or vomiting
• Eye problems, such as blurry vision, seeing double, or losing sight on the sides of the vision
• Seizures
• Trouble thinking, speaking, or understanding language
• Facial numbness or tingling
• Weakness or paralysis in one part or one side of the body
• Confusion and disorientation

While not all brain tumors are cancerous, both benign and malignant tumors can cause serious health issues based on their size and location. It’s important to consult experts at a neurology hospital in Kolkata if you’re experiencing these symptoms.

What is a Brain Tumor?

A brain tumor is an abnormal growth or mass of cells in or near the brain.

Here are a few points that you should know:

• Brain tumors can be malignant (cancerous) or benign (noncancerous).
• Some tumors grow rapidly, while others are slow-growing.
• Only about one-third of brain tumors are cancerous.

Types of Brain Tumor

It can be classified into two types:

• Primary vs. secondary
• By cell of origin / major type

Primary Brain Tumor

Brain tumors that start in the brain are called primary brain tumors.

Secondary Brain Tumor

Tumors that spread to your brain after forming in a different part of the body are known as secondary tumors, or metastatic brain tumors.

Category	Type of tumor (examples)	Brief description
Primary	Glioblastoma (GBM)	These tumors form in glial cells called astrocytes and are the fastest-growing astrocytoma.
Primary	Low‑grade astrocytoma / pilocytic astrocytoma	Usually slow‑growing, often benign or low‑grade glioma.
Primary	Oligodendroglioma (low‑grade or anaplastic)	These uncommon tumors begin in cells that create myelin (oligodendrocytes, a layer of insulation around nerves in your brain).
Primary	Ependymoma	From ependymal cells lining ventricles; usually low‑grade.
Primary	Meningioma	From meninges; usually benign, slow‑growing.
Primary	Pituitary adenoma	From pituitary gland; often benign but hormonally active.
Primary	Schwannoma (including acoustic neuroma / vestibular schwannoma)	From Schwann cells of cranial nerves; usually benign.
Primary	Pineocytoma / pineoblastoma (pineal‑region tumors)	Pineocytoma: benign; pineoblastoma: malignant.
Primary	Medulloblastoma	Embryonal tumor, usually in cerebellum; common in children, malignant.
Primary	CNS lymphoma	Malignant lymphoma arising within the brain.
Secondary (metastatic)	Brain metastases from lung, breast, melanoma, renal, colon, etc.	Tumors spreading to brain from cancers elsewhere; often multiple lesions.

By Cell of Origin / Major Type

Group / origin	Common subtypes (examples)
Gliomas (from glial cells)	Approximately 78% of cancerous primary brain tumors are gliomas. Astrocytoma, glioblastoma (GBM), oligodendroglioma, ependymoma.
Non‑glial (meninges, nerves, glands)	Meningiomas, schwannomas / acoustic neuroma, pituitary adenomas, craniopharyngiomas, pineal tumors (pineocytoma mostly benign, pineoblastoma malignant), choroid plexus tumors (benign choroid plexus papilloma, malignant choroid plexus carcinoma).
Embryonal tumors	Medulloblastoma, other CNS primitive neuroectodermal tumors (PNET).
Germ‑cell tumors	Intracranial germ‑cell tumors (e.g., germinoma, teratoma).
Neuronal / mixed neuronal‑glial	Gangliogliomas, gangliocytomas, anaplastic gangliogliomas.
Structural (skull base, bone, vessels)	Chordomas, glomus jugulare tumors.
Lymphoid origin	Primary central nervous system lymphoma (PCNSL).
Secondary / metastatic	Metastases from lung, breast, melanoma, kidney, colon, etc.

Early Stages of Brain Tumor

Neurologist in Kolkata at IRIS Multispecialty Hospital say early stages of a brain tumor, symptoms are often mild, nonspecific, or slowly progressive. Hence, they can be mistaken for stress, migraine, or “normal aging.” Therefore, always consult your doctor for an accurate diagnosis if symptoms persist.

How to Detect Brain Tumor at Home

Malignant (cancerous) or benign (noncancerous) brain tumors cannot be detected at home, as their diagnosis requires imaging (MRI/CT scans).

These are the actions that you can take at home:

• Keep a symptom diary, such as
  • Weakness.
  • Difficulty walking.
  • Problems with balance.
  • Partial or complete loss of vision.
  • Trouble understanding or using language.
  • Memory issues.
• Monitor worsening symptoms
• Do not self-diagnose
   

What Are the Symptoms of a Brain Tumor

Here is the list in tabular manner:

Type of symptom	Typical signs and features
Headaches	Often worse in the morning, may worsen on lying down, bending, or coughing; may not improve with routine painkillers.
Nausea and vomiting	Frequently associated with headaches; may be more noticeable in the morning.
Seizures	New-onset fits or unusual jerking/loss of awareness, especially in adults with no prior history.
Weakness or numbness	One‑sided weakness, numbness, or clumsiness in arm, leg, or face (often focal).
Balance and coordination	Dizziness, imbalance, stumbling, or difficulty walking.
Vision problems	Blurred vision, double vision, loss of part of the visual field, or drooping eyelid.
Speech and language issues	Difficulty speaking, slurred speech, trouble understanding others, or sudden reading/writing problems.
Memory and thinking change	Forgetfulness, confusion, poor concentration, slowed thinking, or disorientation.
Mood and personality shift	Sudden mood changes, irritability, depression, anxiety, or disinhibited/inappropriate behavior.
Sensory changes	Tingling, odd sensations, or loss of smell on one side; facial numbness or tingling.
Fatigue and drowsiness	Unexplained tiredness, excessive sleepiness, or reduced alertness.
High‑pressure‑type signs	Worsening headaches plus nausea/vomiting, papilledema (swelling of the optic disc), and lethargy indicating raised intracranial pressure.

Diagnosis of Brain Tumor

Experts at the neurology hospital in Kolkata use the following diagnostic tests for accurate analysis:

• Brain MRI or CT scan
• Biopsy
• Spinal tap (lumbar puncture)
• Specialized tests to check tumor markers

What are My Risk Factors for Brain Tumor

In most cases the cause isn't clear however, the following factors can increase the risk:

• Age
• Race
• Exposure to radiation
• Inherited syndromes that increase the risk of brain tumor. Examples include the DNA changes that cause neurofibromatosis 1 and 2, tuberous sclerosis, Lynch syndrome, and Li-Fraumeni syndrome

Conclusion

If you ask, “Are brain tumors curable?” Yes and no, but treatable based on the type, grade, location, and whether they are benign or malignant. Benign (noncancerous) brain tumors can generally be successfully removed with surgery and don’t usually grow back. The key is early detection and treatment. 

Healthcare providers often use a combination of therapies to treat a tumor. Your treatment options might include:

• Watchful waiting/active surveillance (if you have a brain tumor that’s very small and isn’t causing symptoms)
• Brain surgery (craniotomy)
• Radiation therapy
• Radiosurgery
• Brachytherapy
• Chemotherapy
• Immunotherapy
• Targeted therapy

FAQs

Q1: What is a Stage 1 brain tumor?
A: Also known as Grade I brain tumor, which means the tumor grows that slowly and rarely spreads into nearby tissues. It might be possible to entirely remove the tumor with surgery.

Q2: Are brain tumors curable?
A: Yes, they are treatable based on the type, grade, location, and whether they are benign or malignant. If your signs of brain tumor (headaches, seizures, numbness, etc.) persist go for early diagnosis.
