Brain Cancer

Laura Knoll & Makayla Gertken


Most symptoms of brain cancer can include seizures, difficult walking, headaches, weakness, clumsiness, nausea, vomiting, abnormalities in vision, and difficulty sleeping. These common side effects may cause other issues, like brain cell loss and heart problems.


There are a few different treatments for brain cancer some of they more common treatments are chemotherapy and radiation which are used to shrink the cancer tumor or possibly kill the cancer cells. Chemotherapy is given or taken in a few different ways the most common ways are in a pill injection or gel. Radiation is a beam or ray of a laser used to shrink tumors. These treatments are usually done by an oncology nurse.

Radiation treatment

There is three types of radiation treatments for brain cancer:

  • External beam radiation therapy
  • Internal radiation therapy
  • Systemic radiation therapy

Survival rate

Females have a 34.4% chance of surviving brain cancer,

Males have a 31.4% chance of surviving brain cancer.


Charles Wilson is the founder of BTRC ( Brain Tumor Treatment Center) realized that the radiation wasn't working for some of his patients so he diced to try chemotherapy and it was a success. More doctors heard about t

The main cause of brain cancer is when old or damaged cells don't die as they should and build up a mass of tissue called a growth or tumor.

Benign brain tumor:

  • Usually benign brain tumors can be removed
  • Benign brain tumors have an obvious border or edge
  • Benign brain tumors may become malignant
  • Benign brain tumors do not contain cancer cells

Malignant brain tumor:

  • Generally more life threatening
  • Likely to grow rapidly and crowd healthy brain tissue
  • Cancer may break from the tumor and spread throughout the body
  • Rarely spreads throughout the body
  • contains cancer cells

Tumor Grades

Doctors typically grade tumors by the way it looks under a microscope,

Grade I: Tissue is benign, looks nearly normal

Grade II: Tissue is malignant, cells look less than normal

Grade III: Cells look very different and are growing rapidly

Grade IV: Cells look most abnormal and grow quickly

Grades I and II are the lower grades, meaning they look about normal and grow slowly,

grades III and IV are the higher grades, meaning they look abnormal and grow rapidly.

Over time low grades may become high grades.

Risk factors

No one knows the exact cause of brain tumors, but studies show the following risk factors for brain tumors:

  • Ionizing radiation: A high dose of x-rays and other sources can cause cell damage that leads to a tumor.
  • Family history: It's rare for brain tumors to run in a family.


Brain cancer was discovered by Russian scientist, Gupta Longati, It was found in 1873. Longati was observing the brain of a person who had died of a supposed benign brain tumor, he found out that it was actually a malignant growth, which is cancerous.

Personal story

Mary Jean Hansen was diagnosed with stage 4 brain cancer in November of 1999. She was treated with chemotherapy injections and Gama knife surgery which is a laser to shrink the cancerous brain tumors. First she was treated at the Mayo clinic in Rochester. Then she went to Mexico for alternative medical cancer treatments. Mary Jean encountered several near death experiences in Mexico and was rushed by ambulance to the nearest hospital in California, where they were able to stabilize her. Once she was well enough she went back to Mexico for more treatments. Then the doctors sent her home to Minnesota because she was too weak for treatment and the doctors told her once she had regained her strength she should come back for more treatment. This happened twice in the three and a half months she was there and the last time they sent her home she passed away two weeks later on May 5th, 2000 at the age of 57.


In 2075 I think they will have come up with more ways to treat and prevent brain cancer. The doctors then will have a better understanding of what brain cancer is, they will also probably find more treatments that don't require surgery.
