Brain Cancer

Expert Diagnosis & Treatment by Dr. Chandrani Mallik – Leading Medical Oncologist in Kolkata with 15+ Years of Experience

Brain cancer occurs when abnormal cells grow uncontrollably within the brain tissues, forming tumors that can affect vital functions such as movement, vision, memory, speech, and behavior. Tumors may originate in the brain (primary brain tumors) or spread from cancers in other parts of the body (metastatic brain tumors).

With more than 15+ years of experience, Dr. Chandrani Mallik, one of the Best Cancer Doctors in Kolkata, provides advanced, individualized, and compassionate care for patients with all types of brain tumors. Her expertise in medical oncology ensures that patients rec

Common Causes & Risk Factors

While the exact cause of brain cancer is often unknown, several factors may increase the risk:

    • Family history of brain tumors

    • Genetic conditions (e.g., neurofibromatosis, Li-Fraumeni syndrome)

    • Previous radiation exposure to the head

    • Certain immune system disorders

    • Metastasis from cancers such as lung, breast, or melanoma

    • Age-related changes in cellular growth

Signs & Symptoms of Brain Cancer

Symptoms depend on the tumor’s size, position, and growth rate. Common warning signs include:

  • Persistent or worsening headaches

  • Seizures (new-onset or recurrent)

  • Weakness or numbness in arms or legs

  • Vision changes (blurred or double vision)

  • Difficulty with speech or comprehension

  • Memory loss or changes in behavior

  • Loss of balance or coordination

  • Nausea and vomiting without a clear cause

  • Personality or mood changes

Diagnostic Approach for Brain Tumors

Clinical Neurological Examination

Assessment of reflexes, coordination, strength, speech, and cognitive functions.

MRI & Contrast-Enhanced CT Scan

Detailed imaging to identify the tumor’s size, location, and involvement of surrounding brain structures.

PET-CT Scan

Useful for detecting metastasis and tumor activity.

Biopsy / Stereotactic Biopsy

Sampling of tumor tissue to confirm the type and grade of cancer.

Molecular & Genetic Testing

Identifies mutations such as IDH1/2, MGMT methylation, EGFR amplification, or 1p/19q codeletion—critical for treatment planning.

Blood Tests & Hormonal Evaluation

To assess overall health and detect paraneoplastic syndromes.
