Cancer - The Enemy Within
Abstract: Cancer has been known and feared since antiquity, but its imperative danger could only be realized until fairly recently. Indeed as knowledge of the disease grew in the nineteenth and twentieth centuries, fear increased when people became more aware that most cancers had no available cure. Cancer is a disease in which abnormal cells reproduce without control, destroy healthy tissue, and eventually cause deterioration to the body. This paper is a discussion on how cancer develops and spreads, some of the various types of cancer, and the causes of the disease.
Cancer is a disease in which cells multiply without control, destroy healthy tissue, and endanger life. About 100 …show more content…
Sarcomas are cancers that begin in connective tissue. These tissues form the body's supporting structures, such as bone and cartilage. The great majority of cancer cases are carcinomas. They include most cancers of the skin and the breast as well as of digestive, reproductive, respiratory, and urinary systems. Sarcomas also occur in all of these organs and systems but are far less common.
Scientists do not know exactly why cancer develops, but they have found that certain agents play an active role in causing the disease. Most experts agree that people develop cancer mainly through repeated or prolonged contact with one or more cancer-causing agents, called carcinogens. Carcinogens attack normal cells and may eventually cause one of them to become cancerous. Some carcinogens are introduced into the body through the nose, mouth, or some other opening. Other carcinogens attack the body through the skin. Many cancers are caused by a combination of 2 or more carcinogens rather than by a single one.
Laboratory tests and population studies indicate that two main groups of carcinogens can cause cancer in human beings. This groups consist of various chemicals, and certain forms of radiation. Some examples of chemical carcinogens include the tars in tobacco smoke, certain industrial chemicals, certain unnatural food chemicals and also various chemicals used in drugs. Radiation, on the other hand, produces cancer in people who are exposed
Cancer is a disease that is characterized by an “controlled growth and spread of abnormal cells” (What is Cancer?: American Cancer Society). When such a growth takes place, the cancer cells form a tumor from which cells will invade the neighboring tissues and organs. Some of these cells may even travel through the blood or other means to attack other organs and tissues in the body, this is called metastasis (Medline Plus: Metastasis). Different cancers have claimed several million lives over the years. In the 1980s, more than 4.5 million people died in the United States alone from cancer. As time goes by, more and more people get affected by cancer. In the past few years, nine million people developed cancers, and today there are more than 12 million people in the United States receiving
Cancer is a term used for diseases in which irregular cells divide without any control and have the capability to penetrate and infect normal body tissue through the blood and lymph system. Cancer is the second leading cause of mortality in the United States, exceeded barely by heart disease. According to the CDC Cancer Statistics and Data, there were more than 1.45 million people diagnosed with various kind of cancer between 1999 and 2007 and out of those more than 562,000 people died due to cancer (cdc.gov, 2012). Currently there are more than 200 different types of cancer that have been discovered. Cancer could be

Throughout life, many individuals experience difficulties due to growing up in everyday life. While going in depth of the human life, it is discovered that there are many diseases and disorders that affect humans’ everyday functions. A very popular disease that has traumatically affected the human body is cancer. Cancer is a disease that spreads throughout your body in many ways. The purpose of cancer is to attach to a blood cell in your body and cause a plague within itself, causing the body to initially shut down and die. This disease contains many forms and have many causes to it. However its main goal is to destroy the human body.
“One out of every four deaths in the U.S. is from cancer. About 1.2 million new cancer cases are diagnosed in the U.S. annually and about 564,000 Americans will die of it each year-- more than 1,500 people per day” (GrowthHouse). The real question is, what causes cancer? Is it all genetic or do things that we use in our everyday lives cause cancer? There are so many different ideas of what actually causes cancer. There has been a great deal of research in labs to see what increases the risk of someone getting diagnosed with cancer. Research has shown that the effects of chemicals in laundry detergent, sunscreen, hair dye and alcohol are possible causes of cancer.
Cancer is defined as a disease caused by an uncontrollable division of abnormal cells in a part of the body. Cancer can be caused by many variables in one’s environment and the variables that are more likely to cause cancer are often referred to carcinogens. Carcinogens are harmful factors that can increase one’s chance of developing a form of cancer. Carcinogens can be anything from ultra violet rays to dust particles from wood; tobacco is one of the most well-known carcinogens because it increases one’s chances of developing lung cancer by a stagger amount. The reason tobacco has the ability to make such an impact is because tobacco contains more than 70 carcinogens altogether. When it comes down to it, the carcinogens are all working together
Schottenfeld discusses what can cause cancer, how to survive this deadly disease physically, mentally, and emotionally, genetic risks of cancer, moralities, and incidence. The book contains five sections. These sections are labeled Basic Concepts, The Magnitude of Cancer, The Causes of Cancer, Cancer by Tissue of Origin, and Cancer Prevention and Control.
This illustrates how children develop cancer from different types of carcinogenic and genes, this will be used in the introduction of my essay.
While there are several biological factors that have the ability to lead to cancer, genetics is the most currently researched. A study done by Bharaj, Scorilas, Giai and
The American Cancer Society states that cancer is a group of diseases characterized by uncontrolled growth and spread of abnormal cells. If the spread is not controlled, it can result in death (10). According to the Centers for Disease Control and Prevention, cancer is the second leading cause of death. In 2002 alone, half a million Americans will die of this disease. Of this numerical figure, it is estimated that perhaps more than 1,500 individuals a day will die. In addition, one of every four deaths in America is from cancer (9).
“Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the body’s normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor. Some cancers, such as leukemia, do not form tumor”.(‘What is cancer?”) A tumor is the swelling of a part of the body, generally without inflammation, caused by an abnormal growth of tissue, whether benign or malignant. Benign, if the cells are benign they are not cancerous. It won't invade nearby tissues or spread to other areas of the body. Also, some types of benign tumors such as intestinal polyps are considered precancerous and are removed to prevent them becoming
Cancer is a disease that can change the life of a person no matter their age or nationality. Cancer can range from being life threatening to a low risk of death. Cancer cells are cells that do not follow the regular cell growth and division pattern. They go through cell division and produce rapidly. Cancer cells differ from regulating cells in the body because normal cells eventually die. Cancer cells, on the other hand, do not die when they should causing it to be very hard to cure cancer in your body.
