The brain itself is a soft spongy mass of tissue, which is protected by, the bones of the skull, three thin layers of tissue (meninges), and watery fluid (cerebrospinal fluid) that flows through the spaces between the skull and through spaces (ventricles) within the brain. When cells in the brain grow old or get damaged they die and new ones are supposed to take their place. Sometimes though this process does not always happen. The buildup of extra dead cells often form a mass of tissue called a growth or a tumor. There are two kinds of tumors that can form and they are either benign or malignant (cancerous).
Benign tumors usually can be removed and seldom grow back. The cells from benign tumors rarely invade the tissues around them and they do not spread to other parts of the body. However though this does not make them harmless. They can press on sensitive parts of the brain and cause serious health problems and can be life threatening. Benign tumors also have a chance of becoming malignant.
Malignant brain tumors (also called brain cancer) contains cancer cells. These tumors are generally more serious and often a threat to life. They grow rapidly and crowd and invade healthy brain tissue nearby. Cancer cells may break away from the tumors and spread to other parts of the brain or spinal cord. But these cancerous brain tumors rarely spread to other parts of the body.
There are different grades of tumors also, a Grade 1- the tissue is benign, Grade 2-the tissue id malignant, Grade 3- the tissue has cells that look very different from normal cells, Grade 4- the malignant tissue has cells that look most abnormal and tend to grow quickly. Over time low grade tumors can become high grade tumors, but this change tends to occur more in adults than in children.
Primary brain tumors are named according to the type of cells or the part of the brain the tumor originates in.
How you get a brain tumor is still kind of a mystery. Doctors do not know why one person may get one and the other person does not. It relies on the person’s risk factors as to which they have one or not. One risk factor is Ionizing radiation, from high dose x-rays. Another is the person’s family history. Although it is rare for brain tumors to run in a family

Lung Cancer Symptoms and Signs Up to one-fourth of all people with lung cancer may have no symptoms when the cancer is diagnosed. These cancers usually are identified incidentally when a chest X-ray is performed for another reason. The majority of people, however, develop symptoms. The symptoms are due to direct effects of the primary tumor, to effects of metastatic tumors in other parts of the body, or to disturbances of hormones, blood, or other systems caused by the cancer. Symptoms of primary…

Childhood Cancer By: Amanda Bone July 11, 2010 HCA/240 Bruce Gould The body is made up of hundreds of millions of living cells. Normal body cells grow, divide, and die in an orderly fashion. During the early years of a person’s life, normal cells divide faster to allow the person to grow. After the person becomes an adult, most cells divide only to replace worn-out or dying cells or to repair injuries. Cancer begins when cells in a part of the body start to grow out of control. There…
Battling Childhood Cancer Denitra Bowdrey COM/172 March 16, 2015 Lisa Acerbo There are many children around the world whose life is affected by cancer. It is a deadly disease that people struggle with every day. Cancer can grow progressively very quickly, and also be deadly. In even worse cases having to battle cancer at the same time as your child, is the situation for some; but very rare. Can you imagine? But there is hope, luckily we have scientist that are working to cure this disease…
Care of Cancer Kia Nordenskiold September 30, 2012 The Approach to Care of Cancer Cancer refers to a group of diseases that involve uncontrolled cell growth (Corner & Bailey, 2008). The unregulated cell division and growth leads to the formation of malignant tumors that invade bordering body parts. Cancer may also spread to distant areas of the body through the bloodstream or lymphatic system. Determining the causes of cancer is a complex…
Lung Cancer Lung cancer takes years to develop. It results from the uncontrolled growth of abnormal cells in one or both lungs. These cancer cells form lumps and disrupt the lungs, the breathing tubes (bronchi) or both, at times interfering with their normal function. Unfortunately, lung cancer is often not discovered until it has spread (metastasized) throughout the body. Sometimes, however, lung cancer is detected earlier through a chest X-ray or other exam that has been conducted for an unrelated…
* The location of cancer with the highest mortality rate is the lung. * In males, the two locations with the highest incidence of cancer are the lung and the prostate. * In females, the two locations with the highest incidence of cancer are the breast and the colon/rectum. * Three general signs and symptoms of cancer include anemia, weakness, and weight loss. * A carcinogen is a substance that can cause changes in a cell that can lead to cancer. * The number…
Nursing Did you know that one in one hundred new nurses will become a pediatric oncology nurse? Pediatric oncology nursing is a very demanding and heartwarming career. To be a pediatric oncology nurse means to be a primary care coordinator for the management of patients with cancer. A pediatric oncology nurse will assess patient needs, implementing a plan with appropriate tasks for the patient to gain progress. Not only will the pediatric oncology nurse help with the patient, but the family as well…
Cancer is a genetic disease because it can be traced to alteration within specific genes, but in most cases, it is not an inherited disease. The genetic alterations that lead to most cancers arise in the deoxyribonucleic acid (DNA) of a somatic cell during the lifetime of affected individual. Because of these genetic changes, cancer cells proliferate uncontrollably, producing malignant tumour that invade surrounding healthy tissue. As long as the growth of tumour remains localized, the disease can…
1111 Steroid Hormones and Risk of Breast Cancer Barbara S. Hulka, M.D., M.P.H.,* Edison T. Liu, M.D.,t and Ruth A. Lininger, M.D., M.P.H.$ Background. More than three decades of epidemiologic studies have identified numerous risk factors for breast cancer. These factors have been estimated to account for only 20-25% of disease occurrence. However, among these factors, several are related to sex steroid hormones: sex of the affected individuals [women), early age of menarche and late…
