Common Types of Brain and Nervous System Tumors

The central nervous system faces many types of tumors. Each has its own traits. Some are benign, while others are malignant and can harm health a lot.

Primary Brain Tumors

Primary brain tumors start in the brain. They can be either benign or malignant. They are named based on the cell type they come from.

• Gliomas: These tumors come from glial cells. They can be low-grade or high-grade (glioblastoma).
• Meningiomas: Usually benign, these tumors start in the meninges. The meninges are the membranes around the brain.
• Medulloblastomas: Common in kids, these malignant tumors start in the cerebellum.

Metastatic Brain Tumors

Metastatic brain tumors spread from other body parts to the brain. They are more common than primary brain tumors. They are a big worry in cancer treatment.

1. Lung cancer: Often spreads to the brain.
2. Breast cancer: Also spreads to the brain a lot.
3. Melanoma: Known for spreading aggressively to the brain.

Spinal Cord Tumors

Spinal cord tumors can be benign or malignant. They are sorted by where they are in relation to the spinal cord.

• Intramedullary tumors: These start inside the spinal cord.
• Extramedullary tumors: These start outside the spinal cord but inside the spinal canal.

Knowing about these tumor types is key for making good treatment plans. It helps improve patient results.

Initial Symptoms and Warning Signs

It’s key to spot the signs of brain tumors early. This can lead to better treatment and outcomes. Brain tumors can show up in many ways, making it hard to catch them early.
