A brain tumor diagnosis can leave people with more questions than answers. The first detail doctors often give is the location of the tumor. That sounds like a technical detail at first, but it can often provide a lot of information. It can help clear up any pre-diagnosis symptoms that didn't seem to be related. If someone is having trouble with balance, there is a chance that there is a tumor in one area of the brain. If someone else has a problem with speaking, they might have a tumor in a totally different part of the brain.
Different Parts of the Brain do different jobs
The brain isn't one single structure performing one task. Each area has a specific role. That's why the location of a tumor can influence how a person feels and what symptoms appear.
Brain Area | Common Tumor Types | Common Symptoms |
Cerebrum | Glioma, Astrocytoma | Seizures, memory problems, speech difficulties, weakness |
Cerebellum | Medulloblastoma | Poor balance, dizziness, and coordination problems |
Brain Stem | Brain Stem Glioma | Double vision, swallowing difficulties, facial weakness |
Pituitary Gland | Pituitary Tumor | Headaches, vision changes, hormone-related symptoms |
If a tumor forms in the Cerebrum
The largest part of the brain is the cerebrum. It is involved in thinking, talking, recalling, learning, and movement control. Tumors that develop here can affect daily activities in different ways. Others experience difficulty speaking. Some people may have seizures, forgetfulness, or arm/leg weakness. The symptoms often depend on the exact part of the cerebrum where the tumor is growing.
Tumors that affect coordination
The cerebellum is located in the back of the brain and is involved in movement and balance. If a tumour does grow in this area, walking, climbing up and down stairs, or quick turns can become harder to do. Individuals complain about being unsteady or unusually clumsy. Other common symptoms include dizziness and problems with coordination. One tumor commonly encountered in this area—especially in children—is medulloblastoma.
Tumors in the brain stem
The brain stem is the part of the brain that joins the brain to the spinal cord. It regulates functions that people don't typically consider, such as swallowing, eye movement, and breathing. It is important to note that many vital pathways traverse this region and, therefore, even a small tumor can cause symptoms. Speech may be affected, swallowing may be hard, and weakness or double vision of the face may develop.
Tumors of the pituitary gland
The pituitary gland is a tiny, hormone-producing gland at the base of the brain. It is a small gland that has hormones that affect several processes in the body. If a tumor grows in this area, a person may experience symptoms related to hormone changes, such as headaches, vision changes, irregular periods, or other symptoms.
Why do doctors pay close attention to location?
The name of a brain tumour only tells part of the story. The location where it grows can be as significant. Patients can have the same tumor but very different symptoms, depending on which part of the brain is involved.
The location of the tumor allows doctors to plan treatment and lets patients understand the reason why they had the symptoms in the first place. For many people, understanding that connection can make a diagnosis feel a little less confusing.
