A brain tumor is an unnatural division and growth of cells that occurs within brain tissue, the skull lining, or glands. These are either primary (inside the brain, the lining, or pituitary/pineal glands) or secondary (tumors that have developed after the cancer has spread to the brain from another area of the body).
While there are some symptoms associated with brain tumors, they usually do not appear until the tumor has enlarged. However, there are still some early signs that can indicate this condition is present, including seizures, memory loss, personality change, speech problems, headaches, and vision problems.
