The Structure in affect brain Tumor have on people.
A brain tumor is abnormal growth of tissue in the brain or central spine that can disrupt proper brain function. Doctors refer to a tumor based on where the tumor cells originated, and whether they are cancerous (malignant) or not (benign). Benign: The least aggressive type of brain tumor is often called a benign brain tumor. They originate from cells within or surrounding the brain, do not contain cancer cells, grow slowly, and typically have clear borders that do not spread into other tissue. Malignant: Malignant brain tumors contain cancer cells and often do not have clear borders. They are considered to be life threatening because they grow rapidly and invade surrounding brain tissue

Grade system describes how much the tumor cells look like healthy cells when need under a microscope. If the tumor looks similar to healthy tissue and contains different cell grouping its differentiated or a low-grade tumor. If the tissue looks very different from heathy tissue it’s a high- grade tumor. Generally, the lower the grade the better the prognosis, which the chance of recovery, and likelihood of controlling the tumors growth over a long period of time.
Grade 1: Grouped juvenile polycystic tumor, slowly growing tumor that can often be cared with surgery.
Grade 2: Does not have dead cells in the tumor necrosis but shows hyper cellular.
Grade 3: hypercllurlar and cells that are actively dividing mitosis.
Grade 4: tumor usually actively dividing and if blood vessel growth and areas of dead

Survival rates vary dramatically by type of cancer and the stage at which it is diagnosed. With the range of almost no one surviving as long as five years after diagnosis. Once a cancer has spread beyond its original site. The prognosis normally become much worse.
The entire tumor was removed, however microscopic cells may remain as gross total. And large poison of the tumor were removed as subtotal, only part of the tumor remade as partial, while a small portion, used for a biopsy only.
Tumor can form if any part of the brain. Some tumor location. Cause more damage hand others, and some tumors are harder to treat because of their location. Recovery from a brain tumor is not always possible. If treatment is not successful, the disease may be called and advanced or terminal brain tumor.
Doctors are working hard to learn more about brain tumors. Ways to prevent them, how to treat them, and how to provide the best care to people diagnosed with brain tumors. We did a survey of our members who have a brain cancer and asked what signs or symptoms did they have that made them think "do I have a brain cancer?" and how they were diagnosed with a brain cancer. This is what they said:
Survey Results as Of
Because of advancements in technology and funding survival rates have increased in each patient and quality of life due to better chemotherapy and radio therapy drugs are helping millions of survivors round the world to lead a generally normal life without the risk of the cancer returning.
but they are often more aggressive in adults than children. In adults, tumors in the hypothalamus are more likely to be metastatic (resulting form the spread of cancer form another organ to the hypothalamus) than they are when they occur in children. Peter Heage, of Colorado, was diagnosed with a hypothalamic brain tumor. He said that he was having headaches too often,
Glioblastomas (GBM) are tumors that arise from the supportive tissues of the brain. These supportive tissues are composed of astrocytes, star-shaped glial cells that play a very important role in neural functioning. Glioblastomas are highly malignant because astrocytes reproduce quickly and are supported by a large network of blood vessels. Although they are generally found in the cerebral hemispheres of the brain, glioblastomas can be found anywhere in the brain or spinal cord. The tumors come from normal brain cells, so it is easy for them to invade and live within normal brain tissue. However, glioblastoma rarely spreads elsewhere in the body. (1)
Although, it is easy to believe that all cells in a tumor are neoplastic, evidence suggests otherwise. There are three characteristics that are present in all KS cells whether they are neoplastic or not. The first is absence of a histologically distinguishable neoplastic cell. The second is the lack of usual chromosomal abnormalities. The last is a combination of three features angiogenesis, inflammation, and proliferation.
The distribution of the type of brain and CNS tumors is shown in Figure 2.
There are two main categories of brain tumors as to the seriousness; Malignant, and Benign. A Malignant tumor can grow and spread aggressively, and overpower other healthy cells by taking their space, blood, and nutrients. A Benign tumor is less serious than a Malignant, however, it can still cause many problems in the brain by pressing on nearby tissue. They are typically slow growing and rarely spread to other parts of the body. Benign brain tumors can be considered Malignant if they are located in areas of the brain that control vital functions like breathing. Unlike benign tumors, the cell structure of a malignant brain tumor is largely different than normal brain cells. Malignant tumors tend to grow faster and can be more invasive than benign tumors. They are also are life threatening. Tumors are classified as grades one through four. The more aggressive a brain tumor is, the higher the score. Another type of tumor is the pituitary tumor. A pituitary tumor is an abnormal growth of cells in the pituitary gland. It’s about the size of a pea and it’s located at the center of the brain behind the nose and eyes. "Malignant and Benign Brain Tumors."
It was a benign tumor that continued to grow for three years to the size of a basketball, weighing approximately 10 pounds.
Surgery is the oldest type of treatment for cancer. In its earlier use, surgery was not as successful as it is today. This was due to the difficulties involved with the anesthesias, excessive blood loss, respiratory distress, and a number of other complications. Tumors were removed, but metastases had formed, and the cancer returned quickly. In modern day surgery, namely laser surgery, these difficulties do not occur as readily. There are four basic ways to use surgery. One way is a diagnostic biopsy. This is a technique that involves removing part of the tumor, in order to test for malignancy. Another technique is surgery that removes the primary tumor. A third technique is removal of lymphatic tumors and metastases, which can help reduce the recurrence of cancer. The fourth technique is a combination of surgeries to detect and treat a malignant or benign tissue mass (1).
A Brain Tumor is a mass of abnormal cells that vary in size. They can also be classified as Benign or Malignant. Benign Tumors are non-cancerous, and have definite borders that make removal of the entire mass possible. On the other hand, Malignant (Cancerous) Brain Tumors spread, aggressively invading nearby tissue, and have a higher chance of recurring after surgical removal.
The second most typical tumors found in children are brain tumors. Brain tumors are the primary cause of childhood death as they are escalating in frequency. Doctors have found ways to advance their imaging of these brain tumors to help pinpoint the exact location of the tumors, increasing the chance of the children’s survival (Conway, Asuncion, and DaRasso 1). The diagnosing procedure is a crucial process, helping to gain information about the child’s tumor. Brain tumors range in different types of tumors and forms of treatment that can lead to major effects on the children and their families.
According to SEER Statistics, 23,380 people are estimated to get a brain or nervous system cancer diagnosis. Out of those people, 14,320 people are estimated to die from their brain or nervous system cancer diagnosis (National Cancer Institute). Cancer is a type of dangerous tumor, or a buildup of extra cells that form a mass of tissue, that can be life threatening (National Cancer Institute). The term for a tumor that is cancerous is a malignat tumor, whereas a benign tumor does not contain cancer cells (National Cancer Institute). According to the National Cancer Institute, the causes of brain cancer are unknown, but risk factors include family history and excessive radiaton exposure. Although they are not always due to a brain tumor, comon symptoms include headaches, nausea, speech, hearing, vision, and mood changes, problems with balance and mamories, seizures, and numbness in arms and legs (National Cancer Institute). MRI and CT scans as well as surgical biposies (or the removal of part of the tumor to be examined) are used to diagnose brain cancer (National Cancer Institute). Different types of treatment options include radiation therapy, surgery to remove the tumor, and chemotherapy. According to Charles Davis, MD, PhD and Nitin Tandon, MD of WebMD.com, chemotherapy is “ the use of powerful drugs to kill tumor cells”. There are a few different types of chemotherapy, but all of which bring out the same kinds of side effects. Although the physical side effects of chemotherapy are commonly known, few people know of the emotional toll chemotherapy can take on a patient and his or her family as they go though this process.
Bratton, R. L., Whiteside, J. W., Hovan, M. J., Engle, R. L., Edwards, F. D. (2008). Diagnosis
According to Essentials of Human Disease and Conditions textbook, “The most important prognostic factors are age at diagnosis, size of the primary tumor, and the presence of tissue invasion or metastases. (American Cancer Society, 2012)
Benign tumors look similar to the tissues that they came from and develop slowly. The tumor remains in the same area that the tumor originated in. Malignant tumors are formed from cells that do not resemble the tissue that they came from. They vary in shape and size. This enables pieces of the tumor to break off and spread to other places in the body.
How does one see the symptoms for childhood cancer? First one must know that there are many different types. There are forty different types of children’s cancer, including: Leukemia, Lymphoma, Sarcomas, cancers of the nervous system, liver cancers, kidney cancer, and more. Out of these cancers, the two most common childhood cancers are Leukemia, and brain tumors. What is leukemia? It is a cancer in which the bone marrow and other organs that produce blood produce and increased amount of immature or abnormal white blood cells. The symptoms of leukemia are paleness, excessive bruising, pain in the joints, and fatigue. Brain tumors are formed when a massive amount of cells are produced on the brain. The symptoms for this are frequent headaches, vomiting, seizures, decreased coordination, weakness, and problems concerning vision.
