Brain Cancer

By Caelan Behn & Justin Ward

What is the definition of cancer

Definition: Cancer of the central information processing center of the body

What are the symptoms of this cancer? How does it impact the people it affects?

Depending on where the tumor is and its type, size, and extent, as well as age, health history, etc. A tumor near an optic nerve may result in vision problems, a tumor located in the front part of the brain may affect concentration, and a tumor in an area that controls motor function may cause weakness, numbness, or difficulty with speech.

How prevalent is this cancer?

12 and 100,000 people a year are diagnosed with brain cancer most common types in adults are Benign meningioma, and glioma

How is it diagnosed?

If you feel you have any symptoms your doctor will do a variety of checks. Your doctor will give you a Neurologic exam where they check your vision, hearing, alertness, strength, coordination, etc. If needed a MRI, CT scan, Angiogram, Spinal Tap, or biopsy

What are the possible causes of brain cancer?

There are many causes of brain cancer, some of which include exposure to radiation, or a genetic inheritance of brain cancer. A small percent of brain cancer occurs because of a genetic inheritance. A more common known cause of brain cancer is exposure to high levels of ionizing radiation, similar to, but not obtained from, the radiation from atomic bombs. The myth about cellphones and microwaves causing brain cancer has not yet been proven to be a direct cause of brain cancer (Mayo Foundation). Another leading cause of brain cancer is cancer spreading to the brain from other parts of the body. This type of cancer is called metastatic brain cancer. Brain cancer tumors that occur first in the brain are known as primary brain tumors. Primary brain tumors are less common then metastatic brain tumors (National Cancer Institute).

What happens at the cellular and molecular level?

Brain cancer occurs when cells have a change in their DNA. This change in the DNA causes the cells to rapidly divide and grow. These cells are known as mutated cells. Cancer is defined as cells rapidly and uncontrollably dividing. This is exactly what happens with brain cancer. The cells in the brain begin to grow and divide uncontrollably. These cells mutate and change over time. They are constantly evolving. Due to this process, the cells begin to develop resistantance to treatments, like medicines and chemicals. The cells continue to divide and separate, therefore forming a mass of cancer cells. This mass is known as a tumor (Mayo Foundation).

What are the treatments of brain cancer? Are there any cures?

Over the years scientist have discovered many treatments for brain cancer and have saved thousands of lives by doing so. When someone is diagnosed with brain cancer they can create a treatment plan to help fight the cancer and survive. There are many treatments that one can go through. The quickest way to remove the cancer is through surgery. Low grade tumors can be removed by surgery alone. High grade tumors grow faster and are more aggressive, these require treatments as well. Radiation therapy helps to slow down the growth of the cancer and, in some cases, radiation can shrink and destroy parts of the tumor. Another leading form of treatment or brain cancer is chemotherapy. This therapy uses chemicals and medicines to attack the tumor. This is the most common treatment for cancer. All of these treatments work hand and hand together. Most of the time it will take more then one form of treatment to stop the cancer (National Brain Tumor Society).

The source for this topic was covered by the Mayo clinic staff. These staff members worked together as educated and experienced people to give information on the symptoms and causes of brain cancer. Mayo clinic has a high reputation being ranked number one in all of the nation. I have heard of this hospital a few times before looking into them for information knowing that they are a good reliable information source when it comes to the field of health & care. I found little to no bias in this source beside clearly stating they are number one in many fields. The main purpose of this article is to inform readers of the symptoms, causes, and what one should do if they find that this may be happening to them. This source of information is very up to date and accurate with the copyright date being October 2nd of 2015. I feel that this organization is very good at keeping up to date with their information so that people know the Mayo Clinic as a very reliable and go to source of information. This source actually covered two of my topics showing tabs allowing you to go into finding information on other related topics. I chose this source because his was my best source covering all of my topic and providing information for other topics related to mine.

Mayo Foundation. "Brain Tumor." Symptoms and Causes. Mayo Foundation, 02 Oct. 2015. Web. 22 Dec. 2015. <http://www.mayoclinic.org/diseases-conditions/brain-tumor/symptoms-causes/dxc-20117134>. I found the Mayo Clinic to be quite helpful while researching information for my smore in science class. The Mayo Clinic is a non-profit organization that has written thousands of articles about many types of diseases. The Mayo Clinic employs many experts and professionals on diseases and illnesses from all over the world. There is not one direct author for the brain cancer article that I used. There were many experts and professionals in the field of brain cancer that came together to write this article. Due to the fact that many different experts collaborated on writing this article there is no bias in this article. This article focus on a general overview of brain cancer so it mainly consists of facts. There is little, to no, opinionated subjects within the article. Since the article was written by a group, the likelihood for the article to be biased is decreased, because it's not just one person's perception of the illness. This article is credible also because it was written this year, the likelihood of the information changing over the course of one year is not high. The information I gathered from this source was consisted of that from many other sources. I found the information to be the same between multiple article and web pages that I read and utilized.
