What is Brain Tumor / Brain Cancer?
What is brain tumor? A brain tumor is an abnormal growth of cells in or around the brain. Some brain tumors are benign, meaning they are non-cancerous, while others are malignant and may be called brain cancer. A benign tumor can still be serious if it presses on important brain areas, while malignant tumors may grow faster and invade nearby tissue. Patients may also search for “brain tumour” because it is the British spelling of brain tumor. The key difference is that brain cancer usually refers to malignant tumors, while the term brain tumor includes both benign and malignant growths.
Types of Brain Tumor
Brain Tumor Types
- Gliomas: Common primary brain tumors that include:
- Astrocytoma
- Oligodendroglioma
- Ependymoma
- Glioblastoma
- Meningiomas: Tumors that arise from the protective coverings (meninges) of the brain and are often benign.
- Pituitary Adenomas: Tumors of the pituitary gland that can affect hormone production.
- Medulloblastomas: Brain tumors that are more commonly seen in children.
- Metastatic Brain Tumors: Tumors that develop when cancer from another part of the body spreads to the brain.
- Treatment: Depends on the tumor type, location, grade, and whether it is a primary brain tumor or metastatic brain cancer.
Brain Tumor Causes & Risk Factors
- Inherited Genetic Syndromes: Certain inherited conditions can increase the risk of developing brain tumors.
- Family History: A family history of brain tumors may increase risk in some individuals.
- Exposure to Ionising Radiation: Previous exposure to radiation, especially to the head, is a known risk factor.
- Immune System Disorders: Certain immune-related conditions may contribute to the development of brain tumors.
- Increasing Age: The risk of some brain tumors increases with age.
- Genetic Changes in Cells: Many brain tumors develop due to genetic mutations within brain cells, which are not always inherited.
- Risk Varies by Tumor Type: The causes and risk factors differ depending on the specific type of brain tumor.
- Seek Medical Evaluation: Persistent neurological symptoms should be evaluated by a doctor rather than being attributed solely to stress, lifestyle, or excessive screen time.
Brain Tumor Symptoms
- Persistent or Worsening Headaches: Especially if they become more frequent or severe over time.
- Seizures: New-onset seizures without a previous history require immediate medical evaluation.
- Nausea and Vomiting: Particularly when associated with headaches or increased pressure inside the skull.
- Vision Problems: Blurred vision, double vision, or loss of vision.
- Speech Difficulties: Trouble speaking, finding words, or understanding language.
- Memory and Personality Changes: Confusion, forgetfulness, mood swings, or behavioural changes.
- Weakness or Numbness: Weakness in the arms, legs, or one side of the body.
- Balance and Coordination Problems: Difficulty walking, dizziness, or poor coordination.
- Drowsiness or Excessive Fatigue: Unusual sleepiness or reduced alertness.
- Symptoms Vary: The type and severity of symptoms depend on the tumor’s location, size, growth rate, and pressure on the brain.
- Medical Evaluation is Essential: Brain tumor symptoms can resemble those of non-cancerous conditions, so imaging tests and specialist assessment are needed for an accurate diagnosis.
- Do Not Ignore Persistent Symptoms: Seek medical attention if neurological symptoms are new, unexplained, or progressively worsening.
Brain Tumor Symptoms in Females
- Persistent Headaches: Frequent or worsening headaches that differ from usual migraine or tension headaches.
- Seizures: New-onset seizures should always be evaluated by a doctor.
- Mood or Personality Changes: Irritability, confusion, anxiety, or noticeable behavioural changes.
- Vision Problems: Blurred vision, double vision, or loss of vision.
- Nausea and Vomiting: Especially when accompanied by headaches or neurological symptoms.
- Memory and Concentration Issues: Difficulty remembering, focusing, or thinking clearly.
- Weakness or Numbness: Weakness in the arms, legs, or one side of the body.
- Balance and Coordination Problems: Difficulty walking, dizziness, or poor coordination.
- Hormonal Changes (Pituitary Tumors): Some brain tumors can affect hormone levels, menstrual cycles, fertility, or lactation.
- Early Medical Evaluation: Persistent, unusual, or worsening neurological symptoms should not be attributed only to stress, hormonal changes, or migraines and require prompt medical assessment.
Early Warning Signs of Brain Tumor
- Persistent or Worsening Headaches: Especially when accompanied by nausea or vomiting.
- New-Onset Seizures: Seizures in someone with no previous history should be evaluated immediately.
- Vision Changes: Blurred vision, double vision, or unexplained vision loss.
- Speech Difficulties: Trouble speaking, understanding language, or finding the right words.
- Memory Loss or Confusion: Noticeable decline in memory, concentration, or cognitive function.
- Personality or Behaviour Changes: Unusual mood swings, irritability, or behavioural changes.
- Weakness or Numbness: Weakness, tingling, or numbness, particularly on one side of the body.
- Balance and Coordination Problems: Difficulty walking, frequent falls, or poor coordination.
- Seek Prompt Medical Attention: New, persistent, progressive, or unexplained neurological symptoms should be evaluated by a healthcare professional without delay.
Brain Tumor Diagnosis
Diagnosis starts when a doctor reviews medical history, performs a neurological examination, and assesses symptoms of tumor in the brain. Imaging is then usually required. MRI brain with contrast is commonly used because it gives detailed brain images. CT scan may be useful in emergency settings or when MRI is not possible. PET scan may be advised in selected cases, especially when metastatic disease or tumor activity needs assessment. Biopsy or stereotactic biopsy may be required to confirm tumor type and grade. A brain tumor diagnosis should be made through medical evaluation, not symptoms alone.
Brain Cancer Treatment Options
- Surgery: Removal of the tumor through procedures such as craniotomy and tumor resection, when safely possible.
- Radiation Therapy: May include conventional radiation, IMRT (Intensity-Modulated Radiation Therapy), stereotactic radiosurgery (SRS), or other precision radiation techniques.
- Chemotherapy: Used for selected brain tumors; temozolomide is commonly prescribed for some high-grade gliomas.
- Targeted Therapy: Recommended in certain cases based on the tumor’s molecular and genetic characteristics.
- Immunotherapy: Used only in selected brain tumors and is not a standard treatment for all patients.
- Tomotherapy: An advanced form of radiation therapy that enables highly precise treatment while minimizing exposure to surrounding healthy brain tissue.
- Personalized Treatment Plan: Treatment is determined by the tumor type, grade, size, location, patient’s age, symptoms, and whether the tumor can be safely removed.
When to See a Doctor
Access to Brain Tumor Care and Local Support
- Consult the Right Specialist: Patients with suspected brain tumor symptoms should consult a neurologist, neurosurgeon, radiation oncologist, or medical oncologist, depending on their condition.
- Diagnostic Imaging: MRI is generally preferred for evaluating brain tumors, while CT scans may be recommended in specific situations.
- Multidisciplinary Care: If cancer is suspected or confirmed, a cancer specialist or a multidisciplinary neuro-oncology team can guide diagnosis and treatment.
- Specialized Brain Tumor Care: Management typically involves a team of neurosurgeons, neurologists, medical oncologists, and radiation oncologists.
- Financial Assistance: Eligible patients may inquire about government schemes or empanelled hospitals offering financial support or free cancer treatment, subject to eligibility criteria and approved guidelines.
Frequently Asked Questions
Brain Tumor and Brain Cancer-FAQs
What Is The Difference Between Brain Tumor And Brain Cancer?
What is brain tumor? It is an abnormal cell growth in or near the brain. Brain cancer usually means a malignant tumor that can grow aggressively.
What Are The Early Symptoms Of A Brain Tumor?
Early brain tumor symptoms may include persistent headaches, seizures, vomiting, vision changes, speech problems, memory changes, personality shifts, limb weakness, or balance difficulty.
What Causes Brain Tumors?
Many brain tumors have no single definite cause. Risk factors may include genetic syndromes, ionising radiation exposure, immune disorders, age, and certain inherited conditions.
Are Brain Tumors Curable?
Some benign or low-grade tumors may be controlled or removed successfully. Curability depends on tumor type, grade, location, spread, patient health, and treatment response.
What Are The Symptoms Of Brain Cancer In Females?
Symptoms of brain cancer in females can include headaches, seizures, vomiting, vision changes, mood or memory changes, weakness, balance problems, and hormone-related symptoms in pituitary tumors.
