Informative Essay: The Cause Of Brain Cancer

Cancer is a word that no one wants to hear or think about, however there are many people

Brain cancer is usually accompanied at first by headaches and seizures. Later symptoms could include nausea, vomiting, fever, change in pulse, and trouble breathing. Other mental changes may also occur such as difficulty in communication. Symptoms greatly depend on the location of the tumor. For example, if the tumor were located on the part of the brain controlling vision, then vision would be affected.

In a recent issue of Science Translational Medicine, researchers at Johns Hopkins University have described how to combine two forms of cancer treatment, chemotherapy and immunotherapy, to improve the outcome of glioblastoma, an aggressive form of brain cancer. In experiments on mice, the researchers showed that chemotherapy delivered locally to the brain rather than systemically can preserve the strength of the immune system and allow for the use of immunotherapy.

Brain cancer develops from cells within the brain. The brain controls the vital functions of the body, including, speech, movement, thoughts, feelings, memory, sight, hearing, and more. Brain cancer affects people in many different ways. Brain cancer is diagnosed at the local stage in 76.6% of people. The 5-year survival for localized brain and other nervous system cancer is 36.3%. Brain cancer will cause anything from headaches to balance and walking problems, changes in your vision, muscle twitches, memory problems, and nausea and vomiting.

The American cancer society estimated that 18,500 people would be diagnosed with brain tumor and those 12,760 men and women would die of brain cancer in 2005.The National Cancer Institute (NCI) estimated that 22,070 new cases of brain and other central nervous system (CNS) cancers would be diagnosed in the United States in 2009. The American Brain Tumor Association (ABTA) clarifies this statistic further by estimating that 62,930 new cases of primary brain tumors would be diagnosed in 2010. By the year 2030, there will be 26 million new cases, and the death toll will reach to around 1.7 million people. According to World Health Organization (WHO), there are more than 120 types of brain tumors.

“Lets not call cancer patients as patients, they are cancer fighters. They are brave hearts” - Vikrmn, Gura. Nowadays, you hear more and more people getting cancer(13). It is a stress that many people worry about. You worry if one of your parents will get it. You pray your children don't’ get it. It’s a constant worry. You watch television and you can get this horrible monster from microwaving your food, drinking bottled water, carrying your phone in your pocket, using deodorant, coloring your hair and much more. Finding a cure for cancer would be a prayer answered for many.

III. Scientists may not know right now why cancer affects certain people but they do know that it has nothing to do with age or gender.

Cancer is a disease that affects human somatic cells. It causes the cells to divide uncontrollably and form masses known as tumors. There are two different

Assisted suicide, whose life is it? In reality it is the person’s life, and if they are suffering from a terminal illness they should get to choose whether or not they want to suffer. One very aggressive form of a terminal illness is the Glioblastoma Multiforme. This type of brain tumor is more common than a person may think it is also very deadly (Markert). Who is to say a person can’t end their terminal illness, pain, and suffering? They are just like every other human being who wants to die with dignity.

Glioblastoma(GB) is the most common primary malignant solid brain tumor in adults1. Known for its aggressive characteristics and poor prognosis, the median survival rates of GB patients remain less than 18 months2,3. Tumor relapse owing to chemotherapeutic resistance is almost universal and GB is no exception, thus reflecting in high mortality and morbidity rates4. The WHO 2016 classification of brain tumors identifies GB tumors based on histology, molecular and genetic characterization into defined transcription profiles such as classical, neural, pro-neural and mesenchymal types5. Additionally, the commonly occurring genetic aberrations of primary GB are amplifications/mutations of EGFR, PDGFRA, PTEN, and of secondary GB are IDH1, MDM2

Cancer causes many deaths across the globe, in the US alone about twenty-five percent of all people who die, die from cancer. Mutations of DNA, can lead to cancer in healthy cells. Once one cell mutates, if it does not die it will replicate itself causing spread of cancer cells (“Cancer”). Harris explains, “Meningitis, is a disease that affects the membranes covering the brain and spinal cord.” Meninges are known as the tissues that surround the brain and spin (“Carcinomatous Meningitis”). As the article “Carcinomatous Meningitis” defines so well, “Carcinomatous meningitis means there is inflammation of the covering of the brain, caused by cancer. It is an uncommon condition caused by cancer cells getting into the thin layers of body

Cancer. We all know someone who has suffered from it or has passed away because of it. Cancer now affects one in every three people, and is the second highest cause of death in the United States. For decades, the medical community has been on the hunt for a cure for cancer, and have been subjected to intense ridicule from the public because of a lack of progression toward a possible cure. In recent years, many scientists, doctors, researchers, and the general public have come to believe that the cure for cancer is being suppressed because of this lack of progress. Those who say it is suppressed claim that the drugs used to treat cancer actually cause cancer, making a patient sicker and sicker. As a result, the patients are forced to spend

Gliomas are the most common brain tumors, with astrocytoma representing more than 75% of them (CBTRUS, 2011). In Egypt, gliomas account for about one-third of primary central nervous system tumors (Zalata et al., 2011). Histological grading is useful for predicting the biological behavior of a neoplasm, and it is a key factor influencing the choice of therapies, particularly for determining the type of adjuvant radiation and specific chemotherapy protocols. Astrocytoma is classified by the WHO into four grades: grade I, pilocytic astrocytoma; grade II, diffuse astrocytoma; grade III, anaplastic strocytoma; and grade IV, glioblastoma multiforme (GBM). WHO grade I and II astrocytomas are regarded as low-grade astrocytomas, and grade III–IV as

Brain cancer can cause many problems in the body. Two horrible symptoms are change in personality and seizures. “Symptoms of brain cancer can depend on several factors including type, size, location, and effect.” Some other symptoms are headaches, vision changes, loss of motor skill, vomiting, speech problems and/or weakness/numbness. A motor skill is a natural reflex, like balance, or movement. These symptoms are just some of the malfunctions that can happen if someone has brain cancer.
