Classification of Brain Tumor

Brain Tumor

A brain tumor — primary or secondary — can cause a variety of signs and symptoms because it can directly press on or invade brain tissue. This can damage or destroy areas responsible for sight, movement, balance, speech, hearing, memory or behavior. Brain tumor symptoms vary from patient to patient, and most of these symptoms can also be found in people who do NOT have brain tumors.

Therefore, the only sure way to tell if you have a brain tumor or not is to see your doctor and get a brain scan. The growth of abnormal cells in the tissues of the brain. Brain tumors can be benign (non-cancerous) or malignantA primary brain tumor is a group (mass) of abnormal cells that start in the brain. This article focuses on primary brain tumors in adults. Brain tumors encompass neoplasms that originate in the brain itself (primary brain tumors) or involve the brain as a metastatic site. Brain tumors (metastatic brain tumors), which are malignant, are more common. These tumors result from cancer that started elsewhere in the body and spread (metastasized) to the brain.

Classification

HISTOPATHOLOGIC CLASSIFICATION — Primary brain tumors are classified by light microscopy according to their predominant cell type and graded based upon the presence or absence of standard pathologic features. Historical attempts at developing a classification system for brain tumors date back to the 1830s. The German pathologist Rudolf Virchow first introduced the term “glioma” in 1860. Virchow was also the first to attempt a correlation of microscopic to macroscopic features of CNS tumors.

Cellular Classification-He classification of brain tumors is based on both histopathological characteristics and location in the brain. Undifferentiated neuroectodermal tumors of the cerebellum have historically been referred to as medulloblastomas, while tumors of identical histology in the pineal region would be diagnosed as pineoblastomas. The nomenclature of pediatric brain tumors is controversial and potentially confusing. Some pathologists advocate abandoning the traditional morphologically-based classifications such as medulloblastoma in favor of a terminology that relies more extensively on the phenotypic characteristics of the tumor.

Primary Brain Tumor

Astrocytomas — these tumors arise from small, star-shaped cells called astrocytes. They may grow anywhere in the brain or spinal cord. In adults, astrocytomas most often arise in the cerebrum. In children, they occur in the brain stem, the cerebrum and the cerebellum. A grade III astrocytoma is sometimes called anaplastic astrocytoma. A grade IV astrocytoma is usually called glioblastoma multiforme.

Brain stem gliomas — These tumors occur in the lowest, stem-like part of the brain. The brain stem controls many vital functions. Most brain stem gliomas are high-grade astrocytomas.

Secondary Brain Tumor

Metastatic brain tumors originate from malignant tumors located primarily in other organs. Their incidence is higher than that of primary brain tumors. The most frequent types of metastatic brain tumors originate in the lung skin (malignant melanoma, kidney (hypernephroma, breast (breast carcinoma), and colon (colon carcinoma). These tumor cells reach the brain via the blood-stream.

Some non-tumoral masses and lesions can mimic tumors of the central nervous system. These include tuberculosis of the brain, cerebral abscess (commonly in toxoplasmosis), and hamartomas

Get It Out of Your Mind And Into a Mind Map

Do you ever feel like you have some great ideas, but when you sit
down to write them, they’re not so great? Or even worse, you can’t
really get a sense of what the ideas were?

In one of my graduate student coaching groups we have been
discussing the difficulty of translating partly formed ideas into words
on paper. One technique that makes use of a normally underutilized part
of our brain is called “Mind Mapping.”

What is a Mind Map?

Tony Buzan, who created the word “Mind Map” and has written extensively on it, describes it as a powerful graphic technique that
makes use of the way our brains naturally work. He says it has four characteristics.

1. The main subject is crystallized in a central image

2. The main themes radiate from the central image as branches

3. Branches comprise a key image or key word printed on an associated line.

4. The branches form a connected nodal structure


How Do You Mind Map?

Mind mapping is best done in color. If you have some markers or
colored pencils, and a sheet of white paper, you’re ready. If you
don’t, just use what you have.

Start with the central idea that you are trying to wrap your mind
around. It could be the big picture (e.g. your next chapter) or a
smaller idea (e.g. the next few paragraphs.) Write it down in one or
two words at the center of the paper, and draw a circle around it. If
there is a symbol or picture that you can put with the words, sketch
that in. The idea is that you are activating the non-verbal side of
your brain. The quality of what you draw is not important, since you
will be the only one seeing it. The same is true for the ideas you come
up with. Don’t edit, just put in what comes to mind.

There are no rules for the way to proceed from here. I tend to break
rules, anyway. The way my mind works, I start thinking of related
ideas, categories, and ideas, which I write in little circles
surrounding the circle in the middle. I then use lines to connect them.

Tony Buzan likes to draw curved lines emanating from the center, and
write the related or associated ideas on the lines. The result looks
like a tree emanating from a central spot.

My technique looks more like a bunch of lollipops.

As you continue to add associated ideas to your outer circles or
branches, you continue to draw the connections. You will notice as you
fill them in that there are cross connections that appear. I find it
helpful to draw lines between those interconnecting ideas.

How Does a Mind Map Help?

The brain is an associative network, and the right hemisphere (in
most people) is responsible for non-verbal, visual, associative and
much creative thinking. Normally when writing, we are mostly making use
of our left hemisphere, which tends towards the analytical,
one-thought-at-a-time approach. Our internal thoughts, however, are not
shaped like that. Thus we have a roadblock as we try to get our
brilliant thoughts on paper.

By using a Mind Map as a starting point for thinking, you can bypass
the blockage and feeling of overwhelm caused by overly analytical
thinking. The Mind Map allows you to see more than one thought at a
glance, and in doing so helps clarify your thinking. It shows the way
ideas are interrelated (or less related than you thought.) It allows
more access to creative, non-linear parts of your brain.

How Can Grad Students and Professors Use Mind Maps?

At this point, you’re probably thinking, “How is it that Gina writes
so brilliantly and clearly? How does she keep all her creative thoughts
straight?” The secret is that I use Mind Maps to write my articles. So
it’s not a high IQ but my Mind Mapping skills that got me where I am
today.

Here are some helpful ways to make use of Mind Mapping.


1. Use it for brainstorming ideas for your proposal or new research project.

2. Make a Mind Map of your next chapter or the one you’re currently stuck on.

3. When planning your career, make a Mind Map to show the pros and cons of your available options.

4. Use a Mind Map to take notes.

5. Mind Mapping can help keep you awake and interested in your subject.

6. Prepare for an upcoming meeting with a Mind Map and use it to explain your ideas.

7. Use it in teaching, both to prepare classes and for handouts.

Play around with Mind Mapping. You’ll find it’s a refreshing break
from the one-foot-in-front-of-the-other way that we approach many
things in life.
