Brain Tumor: What It Is, Causes, Symptoms, Treatment & Types

The human brain is an extraordinary organ with a vast network of neurons and complex operations. However, like any part of the body, it is vulnerable to diseases, including tumors. A brain tumor can significantly affect a person’s health and quality of life. Understanding brain tumors is crucial for early detection and effective management. By gaining insight into their nature, we can better support those affected and raise awareness about potential signs. Here, we will discuss the different types of brain tumors, their causes, their symptoms, how they are diagnosed, and available treatment options.

What is Brain Tumor?

A brain tumor is an irregular mass or expansion of cells within or around the brain. Tumors in the brain and spine together are known as central nervous system (CNS) tumors. Brain tumors can be classified as benign (noncancerous) or malignant (cancerous). Some are overgrowing, while others develop more slowly. Only about one-third of brain tumors are cancerous. 

Brain tumor side effects may include memory loss, personality changes, speech difficulties, and impaired motor skill. However, if they grow large enough to press on surrounding nerves, blood vessels, and tissue, they can affect brain function and overall health.

Types of Brain Tumors

Primary tumors are those that form in the brain, while those spread to the brain from another part of the body are referred to as secondary or metastatic brain tumors. 

There are many types of brain cancer, and they are classified based on the type of cells they come from. The most common types are:

1. Astrocytomas

These tumors start in star-shaped brain cells called astrocytes. They are classified as malignant (cancerous) or benign (noncancerous).

2. Meningiomas

These grow in the meninges, which are thin tissue layers that cover the brain and spinal cord. Most meningiomas are noncancerous, but some can be cancerous.

3. Pituitary Adenomas

These tumors arise in the pituitary gland, a tiny gland located near the brain’s base that controls hormone production. They can be benign or malignant.

4. Craniopharyngiomas

These tumors form near the pituitary gland and can affect how it works. They are usually benign but can sometimes be cancerous.

What are the Causes of Brain Tumors?

The precise reason for brain tumors is often unknown, but several factors may contribute to their development, including:

• Genetic components
• Radiation exposure
• Some chemicals and viruses
• Previous cancer in another body part

Some tumors are caused by abnormal cell growth that isn’t cancerous (benign). These tumors don’t usually spread to other parts of the brain or body and can often be treated successfully. However, if they grow large, they can still cause severe issues by pressing on essential areas of the brain.

In many cases, the actual cause of a tumor is unknown. Still, research has identified some risk factors that may raise the chances of developing it. 

Common Symptoms of Brain Tumor

The main symptoms of brain tumors can vary based on the brain tumor’s location, size and type. Common symptoms include:

1. Headaches

Headaches are the starting symptoms of brain tumors. They are commonly described as dull and continuous. They get worse when you cough or strain and usually start worse in the morning and get better throughout the day.

2. Seizures

Seizures are caused by abnormal brain activity. They can be moderate or severe, and severe cases can result in loss of consciousness.

3. Nausea and Vomiting

Vomiting and nausea are frequent signs of brain tumors, particularly when the tumor is situated in the part of the brain that controls these processes.

4. Fatigue

Fatigue is a common symptom of tumors. The tumor can increase the pressure on the brain, leading to tiredness.

5. Changes in Vision

A tumor pressing on the optic nerve or producing bleeding in the eye might result in double sight, blurred vision, or loss of peripheral perception.

How to Diagnose Brain Tumors

Let’s discuss how to detect a brain tumor. This procedure involves several phases and may vary depending on the type of tumor.

1. Physical Examination

It starts with a physical examination, where the doctors check your symptoms and rule out other possible conditions. This may include testing your reflexes, coordination, and muscle strength to see if there are any signs that the brain is affected.

2. Imaging Tests 

The doctor will use imaging tests like an MRI (Magnetic Resonance Imaging) or CT scan (Computed Tomography) to get a detailed view of your brain. These scans help identify if a tumor or mass is present and its location.

3. Biopsy 

How is brain cancer diagnosed?  A biopsy is necessary to validate the diagnosis.

A small sample of the tumor’s tissue is taken and tested in a lab to specify whether it is benign or malignant and to understand its specific characteristics.

Brain Tumor Treatment 

Brain tumor treatment depends on the kind of tumor and the extent of the tumor. Radiation therapy, chemotherapy, and surgery are the three primary treatments:

1. Surgery

Surgery is the most prevalent method for treating brain tumors. The goal is to remove as much of the tumor as feasible while maintaining healthy brain tissue. The surgical procedure may vary based on the size and location of the tumor.

2. Radiation therapy

This treatment uses high-energy beams to destroy or stop the growth of cancer cells. Radiation therapy can be used on its own or alongside surgery or chemotherapy, depending on the tumor’s characteristics.

3. Chemotherapy

Chemotherapy is the use of substances to kill cancer cells or keep them from developing. It can be administered through a vein or orally as a pill and is used in combination with surgery or radiation therapy for a more effective treatment plan.

Conclusion

Brain tumors are severe medical conditions that impact physical and mental health. Understanding their causes, symptoms, and treatments is crucial for early detection and effective management. Additionally, lifestyle choices, including nutrition and exercise, may play a role in the development of a tumor, so making informed decisions about your health is essential.
