What is Brain Cancer?

Brain cancer, also known as brain tumor, is an overgrowth of cells in the brain that forms masses called tumors. This type of cancer can be primary or metastatic, meaning it can originate from the brain itself or spread to the brain from another part of the body.

Types of Brain Tumors

There are several types of brain tumors, including:

• Primary brain tumors: These tumors develop in the brain cells themselves and are more common in children and young adults.
• Metastatic brain tumors: These tumors are made up of cancerous cells that have spread to the brain from another tumor elsewhere in the body.

Causes and Risk Factors

The exact cause of brain cancer is still unknown, but research suggests that it may be linked to genetic mutations, environmental factors, and lifestyle choices. Some risk factors for developing brain cancer include:

• Age: Brain cancer can occur at any age, but it's more common in adults 40-70 years old and children 3-12 years old.
• Genetics: Certain genetic conditions, such as Li-Fraumeni syndrome, may increase the risk of developing brain cancer.

Symptoms

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

• Headaches
• Nausea and vomiting
• Balance problems
• Weakness or numbness in the face or extremities

Treatment Options

Treatment for brain cancer depends on several factors, including the type and location of the tumor, as well as the patient's overall health. Treatment options may include:

• Surgery: To remove the tumor
• Radiation therapy: To kill cancer cells
• Chemotherapy: To treat cancer that has spread to other parts of the body

Prognosis

The prognosis for brain cancer patients varies depending on the type and stage of the disease. With early detection and treatment, some patients may experience a complete recovery.

Common Signs and Symptoms of Brain Cancer

Brain cancer can cause a variety of neurological symptoms, as well as systemic effects. The signs and symptoms often correspond to the location, size, and type of tumor in the brain.

• Headaches: Headaches are one of the most common symptoms of brain cancer, and they may be more severe in the morning or wake you up at night [1].
• Seizures: Seizures can occur due to the compression of the brain stem or other parts of the brain [2].
• Difficulty thinking, speaking, or understanding language: Brain tumors can affect cognitive function, leading to difficulties with speech, language, and memory [3].
• Personality changes: Changes in personality or behavior are also common symptoms of brain cancer [4].
• Vision loss or blurred vision: Tumors in the visual pathway can cause vision problems, including blindness [5].
• Nausea and vomiting: Nausea and vomiting can occur due to increased intracranial pressure or other factors [6].
• Fatigue: Fatigue is a common symptom of brain cancer, which can be caused by various factors, including anemia, sleep disturbances, or the tumor itself [7].

Other Possible Symptoms

In addition to these symptoms, brain cancer can also cause:

• Sleep and eating disorders
• Water balance problems
• Obesity
• Sleep disturbances
• Emotional changes
• Excessive thirst and urination

It's essential to note that some of these symptoms can be caused by other medical conditions. If you're experiencing any of these symptoms, it's crucial to consult a doctor for proper evaluation and diagnosis.

Diagnostic Tests for Brain Cancer

Brain cancer diagnosis involves a combination of physical examination, medical history, and various diagnostic tests to confirm the presence of a tumor and its type. Here are some common diagnostic tests used to diagnose brain cancer:

• Imaging Tests: These tests use imaging technologies to visualize the brain and detect tumors.
  • Computed Tomography (CT) Scan [8]: A CT scan is usually the first test ordered, which uses X-rays and computer technology to produce detailed images of the brain.
  • Magnetic Resonance Imaging (MRI) Scan [9]: An MRI scan uses a strong magnetic field and radio waves to create detailed images of the brain. It's often used to confirm the presence of a tumor and its location.
• Blood Tests: These tests can detect substances in the blood that may indicate cancer, such as hormones, proteins, or chromosomes. However, lab tests cannot diagnose a brain tumor [11].
• Lumbar Puncture (Spinal Tap): This test involves withdrawing cerebrospinal fluid from the spine to check for cancer cells [3]. It's mainly used to look for cancer cells in the cerebrospinal fluid.
• Biopsy: A biopsy involves removing a small sample of tissue from the tumor and examining it under a microscope. It's often performed during surgery or using a needle [7].
• Other Tests: Other tests, such as X-rays, PET scans, MRIs, CT scans, surgical biopsies, and liquid biopsies, may be used to diagnose brain cancer [15].

Important Notes

• Brain tumors are not staged like other types of cancer, as they don't spread in the same way.
• The prognosis for brain cancer depends on various factors, including the type and location of the tumor, age, and overall health.
• Early detection is crucial for effective treatment options.

Treatment Options for Brain Cancer

Brain cancer treatment options have evolved significantly over the years, and drug therapy has become a crucial part of managing this complex disease.

• Targeted Therapies: These drugs specifically target the genetic mutations that drive brain cancer growth. For instance, vorasidenib (approved by the FDA in 2024) is a targeted therapy for IDH-mutant low-grade glioma [1][2]. This type of treatment works by inhibiting the activity of a mutated gene called IDH.
• Chemotherapy: Chemotherapy involves using drugs to kill cancer cells. Common chemotherapy drugs for brain tumors include temozolomide, procarbazine, lomustine, and vincristine (PCV) [3][4]. These medications can cause side effects like nausea, fatigue, and hair loss.
• Corticosteroids: Corticosteroids are used to reduce swelling in the brain caused by tumors. They can also help alleviate headaches and pain [5].
• Anticonvulsants: Anticonvulsants are prescribed to prevent seizures or convulsions associated with brain cancer [6].

Other Treatment Options

In addition to drug therapy, other treatment options for brain cancer include:

• Surgery: Surgery may be necessary to remove the tumor.
• Radiation Therapy: Radiation therapy uses high-energy rays to kill cancer cells.
• Tumor Treating Fields (TTFields): TTFields is a non-invasive treatment that uses electrical fields to slow down or stop cancer cell growth.
• Clinical Trials: Clinical trials are ongoing research studies that may offer new and innovative treatments for brain cancer.

Side Effects of Treatment

While treatment options have improved, it's essential to be aware of potential side effects. These can include:

• Nausea and vomiting
• Fatigue and weakness
• Hair loss
• Seizures or convulsions

It's crucial to discuss these risks with your healthcare provider and weigh the benefits against the potential drawbacks.
