Signs of Brain Tumors
No blood test or other screening exam can detect brain tumors, but there are often some outward signs. While tumors in different parts of the central nervous system disrupt different functions, some symptoms include:

• Headaches.

• Nausea/vomiting.

• Seizures.

• Weakness or numbness on one side of the body.

• Changes in vision, hearing or sensation.

• Difficulty with speech.

• Lack of coordination.

• A change in mood or personality.

• Memory loss.
