When brain tumors are very small, some people may not experience any symptoms or the symptoms are so minimal they don’t notice them.
As brain tumors grow, signs and symptoms can vary and largely depend on the tumor’s location within the brain, its size, and how quickly it grows.

Areas of the Brain
Some people with brain tumors experience general symptoms like headaches, seizures, and fatigue. Other symptoms can be more specific to the location of the tumor in the brain.
Brain tumors can damage healthy tissue, press on healthy brain tissue, or cause pressure in the brain and negatively impact certain functions.
If you are diagnosed with a brain tumor, ask your provider where it is located in the brain to better prepare for possible symptoms and safety concerns.

The cerebrum is the uppermost and largest part of the brain. It processes sensation, generates thought, and controls conscious activity. The cerebrum has two sides — the right and the left hemispheres that each control the opposite side of the body — and each side is divided into four lobes with specific functions: the frontal lobe, the parietal lobe, the temporal lobe, and the occipital lobe.
There are five additional areas that can be affected by the location of the tumor.
