Brain Cancer Symptoms, Causes & Types – What Patients Should Know

Being diagnosed with brain cancer can feel overwhelming, but treatment has come a long way. Depending on the type, size, location, and whether the tumor is benign or malignant, your care team will develop a personalized plan to provide the best chance for recovery and quality of life.

Brain Cancer at a Glance: Symptoms, Causes & Types

Brain cancer occurs when abnormal cells form within the brain and begin to grow uncontrollably, potentially disrupting critical body functions. These tumors may be primary (originating in the brain) or secondary/metastatic (spreading from cancers elsewhere in the body, often from the lungs, breast, kidney, or skin).

Symptoms of Brain Cancer

Because the brain controls so many body functions, symptoms can vary widely based on tumor location, size, and rate of growth. Common signs include:

• Headaches that worsen over time or with movement

• Seizures

• Memory loss or confusion

• Difficulty speaking or understanding language

• Changes in personality or behavior

• Nausea or vomiting

• Vision or balance problems

If you’re experiencing persistent or unusual neurological symptoms, speak with your healthcare provider.

What Causes Brain Cancer?

The exact causes of brain cancer are still unclear, but a few risk factors have been identified:

• Age: Risk increases with age, especially after 65.

• Radiation exposure: Especially in childhood or as a result of prior cancer treatment.

• Weakened immune system: Associated with an increased risk for certain brain lymphomas.

• Genetics: Certain rare genetic conditions may increase risk.

• Gender: Some brain tumors are more common in men, while others (like meningiomas) occur more often in women.

Importantly, brain cancer does not typically run in families.

Types of Brain Tumors

Brain tumors are classified based on the type of cells involved and how quickly they grow. While not all brain tumors are cancerous, even benign tumors can be life-threatening depending on their location.

Common Primary Brain Tumors:

• Gliomas: The most common type, arising from glial cells. Includes:

  • Astrocytomas (Grade I–IV, including glioblastoma)

  • Ependymomas

  • Oligodendrogliomas

• Meningiomas: Typically benign, arising from the brain’s protective lining

• Pituitary tumors: Usually benign but can impact hormone levels

• Schwannomas: Often benign tumors affecting nerves

• Primary CNS lymphomas: A rare, aggressive form of non-Hodgkin’s lymphoma in the brain

Why Awareness Matters

Only about 30% of brain tumors are malignant, but all brain tumors require attention. Awareness encourages early evaluation of symptoms, leading to faster diagnosis and potentially better outcomes.

Common treatment options include:

• Surgery

• Radiation Therapy

• Chemotherapy

• Targeted Therapy

• Clinical Trials
