Lesson Transcript
Instructor: Artem Cheprasov

Artem has a doctor of veterinary medicine degree.

This lesson discusses the basics and definitions of brain tumors, malignant brain tumors, benign brain tumors, gliomas, meningioma, and increased intracranial pressure.

Brain Tumors

If you had more eyes, you would see better. If you had more hands, you'd be able to do more. But if you had more brain cells then, well, that may actually not make you smarter. Sometimes brain cells multiply and form brain tumors, which do not make you any smarter!

A brain tumor is an abnormal growth of tissue in the brain. There are two types of brain tumors. Malignant brain tumors are invasive and, thus, cancerous growths that destroy brain tissue. They may spread to areas outside of the brain. Benign brain tumors are not invasive and do not spread outside of the brain.

But the problem is that even benign brain tumors can kill a person. In this lesson, you'll find out that there are a lot of different types of brain tumors and that even the benign ones can be dangerous.

Types of Brain Tumors

So, what are the different kinds of brain tumors? Well, they're named for the types of cells involved in their formation. They include gliomas, which are tumors composed of neuroglia. Neuroglia are the supporting cells of the nervous system that are much like the foundation and frame that support the home you live in.

There are also the meningiomas, tumors that arise from the meninges, the membranes surrounding the brain. The meninges are like the roof and siding that surround a home. Another kind of brain-tumor type is a pituitary adenoma, a tumor that forms in the pituitary gland, which is responsible for producing and secreting many different hormones.

Gliomas and meningiomas are the most common brain tumors found in adults. The most common form of cancerous brain tumor in children is known as a medulloblastoma, a tumor that begins in the lower back portion of the brain.

Intracranial Pressure

While cancerous brain tumors get all the bad rap, benign brain tumors can be deadly, as well. Thus, it's not really appropriate to say that a cancerous brain tumor is bad and a benign brain tumor is good. They're all bad!

Here are two major reasons for why benign brain tumors can be so bad. Firstly, the brain sits inside a very hard shell called the skull, with almost no room to spare. This is like you being squeezed tightly into a small closet.
