Occipital Lobe Tumors

Occipital lobe tumors are abnormal growths that occur in the occipital lobes of the brain, which are responsible for processing visual information. These tumors can cause a range of problems and require prompt diagnosis and treatment. In this article, we will discuss various aspects of occipital lobe tumors in simple, easy-to-understand language.

Types of Occipital Lobe Tumors:

1. Gliomas: These are the most common type of brain tumors and can develop in the occipital lobe.
