Beating Brain Tumor Cancer: Key Facts and New Treatments

Brain Tumor Cancer: What is it?

Brain tumor cancer is a serious condition where abnormal cells grow in the brain, affecting its normal functions. “Tumors of the central nervous system (CNS) constitute approximately 2% of all malignancies.” NIH

This condition can be scary, but understanding it better can help us manage and treat it effectively. A brain tumor is an abnormal growth of cells within the brain. These tumors can be either benign (non-cancerous) or malignant (cancerous). Brain tumor cancer refers to the malignant tumors that can invade and destroy nearby brain tissue. These tumors can start in the brain (primary brain tumors) or spread to the brain from other parts of the body (secondary or metastatic brain tumors). In this guide, we will explore what brain tumor cancer is, the different types, symptoms, risk factors, how it is diagnosed, and the available treatment options.

What are the Types of Brain Cancer?

There are several types of brain cancer, classified based on the cells they originate from and their behavior. The main types of brain cancer include:

1. Gliomas: These tumors arise from glial cells, which support and protect nerve cells in the brain. Gliomas are the most common type of primary brain tumor and include astrocytomas, oligodendrogliomas, and ependymomas.
2. Meningiomas: These tumors develop from the meninges, the protective layers of tissue covering the brain and spinal cord. Most meningiomas are benign, but some can be malignant.
3. Medulloblastomas: These are fast-growing tumors that are most common in children and start in the cerebellum, the part of the brain that controls balance and coordination.
4. Schwannomas: These tumors originate from Schwann cells, which produce the myelin sheath that insulates nerves. They are usually benign and often affect the nerves responsible for hearing and balance.
5. Pituitary Tumors: These tumors develop in the pituitary gland, a small gland at the base of the brain that produces hormones. Most pituitary tumors are benign, but they can still cause significant health issues by disrupting hormone production.
6. Craniopharyngiomas: These are rare, benign tumors that develop near the pituitary gland and can affect hormone production and vision.

Symptoms of Brain Tumor Cancer

The symptoms of brain tumor cancer can vary widely depending on the size, location, and type of tumor. Common symptoms include:

• Headaches: Persistent or severe headaches, especially if they are worse in the morning or wake you up at night.
• Seizures: Experiencing seizures or convulsions for the first time can be a sign of a brain tumor.
• Nausea and Vomiting: Unexplained nausea and vomiting, especially in the morning, can be a symptom.
• Vision Problems: Blurred vision, double vision, or loss of peripheral vision can occur.
• Balance and Coordination Issues: Difficulty walking, loss of balance, or problems with coordination can be signs.
• Speech Difficulties: Trouble speaking or understanding speech can be a symptom.
• Cognitive Changes: Memory problems, confusion, or changes in personality or behavior can occur.
• Weakness or Numbness: Weakness or numbness in one part of the body, especially on one side, can be a sign of a brain tumor.

Risk Factors for Brain Tumor Cancer

Several factors can increase the risk of developing brain tumor cancer. These include:

• Age: While brain tumors can occur at any age, certain types are more common in children, while others are more prevalent in adults.
• Family History: Having a family history of brain tumors can increase the risk.
• Exposure to Radiation: Previous exposure to radiation, especially to the head, can increase the risk of brain tumors.
• Genetic Conditions: Certain genetic conditions, such as neurofibromatosis or Li-Fraumeni syndrome, can increase the risk of brain tumors.
• Chemical Exposure: Long-term exposure to certain chemicals, such as those found in the rubber manufacturing or oil refining industries, can increase the risk.

Diagnosing Brain Tumor Cancer

Diagnosing brain tumor cancer involves several steps. If a brain tumor is suspected, a doctor will conduct a thorough medical history and physical examination. Additional tests may include:

• Imaging Tests: MRI (Magnetic Resonance Imaging) and CT (Computed Tomography) scans are the most common imaging tests used to diagnose brain tumors. These tests provide detailed images of the brain and can help identify the size, location, and type of tumor.
• Biopsy: A biopsy involves taking a small sample of the tumor tissue for examination under a microscope. This can help determine if the tumor is benign or malignant and guide treatment decisions.
• Neurological Exam: A neurological exam assesses various brain functions, including vision, hearing, balance, coordination, reflexes, and cognitive abilities.

Treatment Options for Brain Tumor Cancer

The treatment of brain tumor cancer depends on the type, size, location, and grade of the tumor, as well as the patient’s overall health and preferences. Treatment options may include:

Brain Cancer Surgery

Brain cancer surgery is often the first step in treating brain tumors. The goal of surgery is to remove as much of the tumor as possible without damaging healthy brain tissue. In some cases, surgery can completely remove the tumor, but in others, it may only be possible to remove part of the tumor. Advanced surgical techniques, such as awake craniotomy and image-guided surgery, can improve outcomes and minimize risks.

Radiation Therapy

Radiation therapy uses high-energy beams, such as X-rays or protons, to kill cancer cells. It can be used after surgery to destroy any remaining cancer cells or as the primary treatment for tumors that cannot be surgically removed. There are different types of radiation therapy, including external beam radiation and stereotactic radiosurgery, which deliver precise doses of radiation to the tumor while minimizing damage to surrounding healthy tissue.

Chemotherapy

Chemotherapy uses drugs to kill cancer cells. These drugs can be taken orally or administered intravenously. Chemotherapy is often used in combination with other treatments, such as surgery and radiation therapy. Some common chemotherapy drugs used to treat brain tumor cancer include temozolomide, carmustine, and lomustine.

Targeted Therapy

Targeted therapy uses drugs that specifically target the abnormal proteins or genes that drive cancer growth. These drugs can block the growth and spread of cancer cells while minimizing damage to healthy cells. Examples of targeted therapies used in brain tumor cancer treatment include bevacizumab and erlotinib.

Immunotherapy

Immunotherapy helps the body’s immune system recognize and attack cancer cells. This type of treatment can be used alone or in combination with other treatments. Some immunotherapy drugs, such as checkpoint inhibitors, have shown promise in treating certain types of brain tumor cancer.

Clinical Trials

Clinical trials are research studies that test new treatments or procedures. Participating in a clinical trial can give patients access to cutting-edge therapies that are not yet widely available. Clinical trials also contribute to advancing our understanding of brain tumor cancer and improving treatment options for future patients.

Living with Brain Tumor Cancer

Living with brain tumor cancer can be challenging, both physically and emotionally. It is important for patients and their families to seek support and resources to help them cope with the diagnosis and treatment. Support groups, counseling, and patient advocacy organizations can provide valuable assistance and information.

Coping Strategies

• Stay Informed: Understanding the diagnosis and treatment options can help patients feel more in control and make informed decisions about their care.
• Build a Support Network: Connecting with family, friends, and support groups can provide emotional support and practical assistance.
• Focus on Self-Care: Taking care of one’s physical and emotional health is important. This can include regular exercise, a healthy diet, and activities that bring joy and relaxation.
• Communicate with Healthcare Providers: Open communication with doctors and healthcare team members can ensure that patients receive the best possible care and support.

Sum up,

Brain tumor cancer is a complex and serious condition that requires a comprehensive approach to diagnosis and treatment. Understanding the different types of brain cancer, recognizing the symptoms, and knowing the available treatment options can empower patients and their families to navigate this challenging journey. Advances in brain cancer treatment and ongoing research offer hope for improved outcomes and a better quality of life for those affected by this disease. By staying informed and seeking support, patients can take an active role in their care and work towards the best possible outcomes.
