World Brain Tumor Day: Brain Health and Prevention

On World Brain Tumor Day, we join the global effort to raise awareness about brain tumors and honor those affected by this challenging condition.Today, let’s recognize the importance of continued research, innovation, and support in the fight against brain tumors. Together, we can drive progress towards a future where brain tumors are effectively diagnosed and treated.

Understanding Brain Tumors:

A brain tumor is an abnormal growth of cells within the brain or the central spinal canal. Tumors can be benign (non-cancerous) or malignant (cancerous). While benign tumors are less aggressive, their growth can still lead to serious health issues due to pressure on brain structures. Malignant tumors, however, are more dangerous as they grow rapidly and invade surrounding brain tissue.

?Brain Tumor Statistics in India:

In India, brain tumors represent a significant health challenge, with an estimated incidence rate of 5 to 10 per 100,000 individuals. Each year, approximately 40,000 to 50,000 new cases are diagnosed, affecting both adults and children. Brain tumors account for around 2% of all cancers in India, but they are particularly concerning because of their impact on quality of life and high treatment costs. The mortality rate remains high due to late diagnosis and limited access to advanced medical facilities, especially in rural areas. Efforts to improve awareness, early detection, and access to modern treatments are crucial in addressing this growing health issue.

Interesting Facts About Brain Tumors:

Diverse Types: There are over 120 different types of brain tumors, classified based on their cell origin and behavior.

Glioblastoma: The most aggressive type of primary brain tumor, glioblastoma, accounts for 15% of all brain tumors.

Children and Brain Tumors: Brain tumors are the second most common type of cancer in children, after leukemia.

Silent Growth: Some brain tumors grow silently without causing symptoms for a long time, making early detection challenging.

Diagnosis of Brain Tumors:

1. Medical History and Physical Examination

The journey begins with a thorough review of the patient’s medical history. Doctors will delve into any symptoms experienced, such as headaches, seizures, or changes in vision, along with assessing potential risk factors like family history.

2. Imaging Tests

Imaging techniques are pivotal in visualizing the brain and spotting abnormal growths. Here are the main tools:

Magnetic Resonance Imaging (MRI): Think of this as a brain’s photo shoot with powerful magnets and radio waves. MRI produces highly detailed images, offering a clear view of brain structures and potential tumors.

Computed Tomography (CT) Scan: Imagine taking numerous X-rays from different angles and assembling them into a comprehensive 3D picture of the brain. This test is especially useful in detecting bone involvement and calcifications.

3. Biopsy

A biopsy is akin to detective work at the cellular level. During this procedure, a small sample of the tumor is removed and scrutinized under a microscope. This step is crucial for identifying the type and grade of the tumor, which directly influences treatment decisions.

4. Laboratory Tests

Laboratory tests can reveal hidden clues about overall health and provide indirect hints about the tumor. At GreenArray, we are dedicated to advancing the detection and treatment of brain tumors through our Comprehensive Cancer panel. By analyzing FFPE tissue or liquid biopsy (CSF), our panel provides comprehensive genomic profiling that is essential for precise diagnosis and personalized treatment plans.

Treatment for Brain Tumor:

Treatment for brain tumors depends on the type, location, and size of the tumor, as well as the patient’s overall health. Standard treatments include:

Surgery: The primary treatment for most brain tumors, aiming to remove as much of the tumor as possible.

Radiation Therapy: Uses high-energy waves to target and kill tumor cells, often used when surgery isn't feasible.

Chemotherapy: Utilizes drugs to kill cancer cells or stop their growth, often used in combination with other treatments.

Targeted Therapy: Focuses on specific molecules involved in tumor growth and survival, offering a more personalized treatment approach.

?

Research and Advances:

Ongoing research is crucial for developing more effective and less invasive treatments. Promising areas include:

Immunotherapy: Leveraging the body’s immune system to fight cancer cells. Clinical trials are exploring various immunotherapy approaches for brain tumors.

Gene Therapy: Investigating methods to correct or modify genes responsible for tumor growth.

Precision Medicine: Tailoring treatments based on the genetic profile of the tumor, improving efficacy and reducing side effects.

Advanced Imaging Techniques: Enhancing the ability to diagnose and monitor brain tumors more accurately and less invasively.

Why is World Brain Tumor Day important?

Brain tumors are among the deadliest disorders, affecting both genders and all ages. They account for 85-90% of primary central nervous system (CNS) cancers. The global incidence rates of primary malignant brain tumors are approximately 3.70 per 100,000 men and 2.60 per 100,000 women annually.

Given these statistics, raising public awareness is crucial in managing the brain tumor burden. World Brain Tumor Day plays a vital role in educating the public about brain tumor screening, diagnosis, and advanced treatment options, helping patients and caregivers make informed decisions.
