How does brain cancer occur?
Brain cancer occurs when brain cells start growing in an uncontrolled way and form a harmful mass. These abnormal cells disturb normal brain functions. It can happen due to genetic changes, radiation, or unknown reasons.

In Delhi, neurosurgeons and neuro-oncologists work closely together. Start with a neurosurgeon for surgical candidacy, who will coordinate with neuro-oncology for comprehensive care planning.
Delhi has advanced technology for brain cancer treatment. Ask your doctor if these facilities are available:
Real-time imaging during surgery ensures maximum safe tumor removal.
Non-invasive, precise radiation for inoperable or residual tumors.
IDH, MGMT, 1p/19q testing to guide personalized treatment decisions.
Speech and motor mapping during surgery to preserve critical functions.
Bevacizumab and other targeted drugs for specific tumor types.
When booking your brain cancer consultation, ask the hospital coordinator if these technologies are available at their Delhi facility. Not all hospitals have the same level of infrastructure.
What should I ask my brain cancer doctor? Here are 5 important questions for your first consultation:
Why it matters: Tumor location determines surgical feasibility and potential risks.
Why it matters: IDH, MGMT, and other markers guide treatment choices and predict outcomes.
Why it matters: Brain mapping during surgery protects critical functional areas.
Why it matters: Radiosurgery may be an option for small or inoperable tumors.
Why it matters: Speech, cognitive, and physical therapy are crucial for recovery.
Our team helps you prepare a list of important questions to ask your doctor, so you can make the most of your consultation. Message us, and we'll be happy to assist you.
Bring all MRI scans (preferably on CD/USB), biopsy reports if done, and list of current medications and symptoms to your consultation.
Selecting the right brain cancer specialist can significantly impact your treatment journey. Here are 6 important factors to help you evaluate doctors and hospitals with confidence.
Choose a neurosurgeon performing 50+ brain tumor surgeries annually with expertise in awake craniotomy for eloquent area tumors. Awake surgery with intraoperative mapping preserves speech/motor function in 85-90% cases vs 60% without mapping.
Ensure the hospital offers comprehensive molecular profiling including IDH1/2, MGMT methylation, 1p/19q codeletion, and EGFR testing within 10-14 days. These markers determine prognosis and guide temozolomide therapy decisions, impacting survival by 6-12 months.
Verify access to intraoperative MRI during surgery. Studies show iMRI increases gross total resection rates by 30-40%, directly improving progression-free survival. Ask if real-time imaging is available or if surgery requires two separate sessions.
For small tumors (<3cm) or post-surgical residual disease, confirm availability of stereotactic radiosurgery (SRS). Single-session Gamma Knife or fractionated CyberKnife offers 90-95% local control with minimal cognitive side effects vs conventional radiation.
Look for hospitals starting physiotherapy, speech therapy, and cognitive rehabilitation within 48-72 hours post-surgery. Early rehab improves functional independence by 40% and reduces hospital stay by 3-5 days. Ask about specialized neuro-rehab units.
For glioblastoma or recurrent tumors, verify participation in immunotherapy trials (checkpoint inhibitors, CAR-T, tumor-treating fields). Trial access can provide treatments 2-3 years before commercial availability. Check hospital's active neuro-oncology trial portfolio.
During your brain cancer consultation in Delhi, ask your doctor about each of these factors. These questions help you identify truly experienced specialists and well-equipped hospitals for the best brain cancer treatment outcomes.

Brain cancer occurs when brain cells start growing in an uncontrolled way and form a harmful mass. These abnormal cells disturb normal brain functions. It can happen due to genetic changes, radiation, or unknown reasons.
A brain tumor happens when healthy brain cells begin to multiply abnormally. This may be linked to genetic mutations, radiation exposure, or random cell changes. Many tumors develop without a clear cause.
A brain tumor is a lump of abnormal cells growing inside or around the brain. It can be non-cancerous (benign) or cancerous (malignant). Both types can cause symptoms by pressing on brain tissues.
Most brain cancers are not inherited, but some rare genetic disorders can increase risk. Many patients have no family history of the disease. In most cases, the cause is not fully understood.
The WHO classifies brain tumors into Grades 1 to 4 based on the type of cells and how fast they grow. Lower grades grow slowly, while higher grades are more aggressive. This classification helps doctors decide the best treatment.
Brain cancer is caused when brain cells develop DNA changes and start growing uncontrollably. Radiation, genetics, and environmental factors may contribute. Often, the exact cause remains unknown.
On MRI or CT scans, a brain tumor appears as an unusual mass or lump inside the brain. Its size and shape differ depending on the type. It may push or compress nearby brain areas.
Blood tests cannot directly confirm brain cancer. Doctors mainly rely on MRI and CT scans for diagnosis. Blood tests are used only to rule out other problems or check overall health.
India's best cancer hospitals for treatment include AIIMS Cancer Institute New Delhi (All India Institute of Medical Sciences), Tata Memorial Hospital Mumbai — the top cancer treatment hospital in India for volume and research — Rajiv Gandhi Cancer Institute & Research Centre (RGCI) Delhi, Adyar Cancer Institute Chennai, and Cancer Institute (WIA) Chennai. Tata Memorial Hospital Mumbai is widely regarded as the best cancer hospital in Mumbai and one of the finest in Asia for top cancer care.
