Cancer And Its Effects On The Human Body

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

If you or someone you love has cancer, the fear and confusion that follows can be overwhelming so understanding the basics of the disease can help. To understand the effect of these abnormal cells it helps to look first at how healthy cells function. Each of us are made up of

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

Cancer is described as the abnormal growth of cells. Normal cells are replaced with abnormal cells in which their deoxyribonucleic acid (DNA) has been damaged or augmented (McCance & Huether, 2014). Cancer cells with their various DNA changes are characterized by growing uncontrollably, being immortal with an unlimited lifespan

What is cancer? This is an important question that will help people to understand the severity of this affliction. Cancer occurs from abnormal cell growth in the human body. When this happens tumors may form. Tumors are a mass of cells that continue to expand. These tumors may be benign. This means they will not spread through the body. Though, the tumors may be malignant which means they may spread to other areas of the body in an invasive manner. These malignant tumors have the potential to cause serious complications and even death. It is these tumors that are cancerous.

Human life starts from a fertilized cell which breaks down, again and again, an adult human body is composed of the abundance of cells and each one have their own specific function to perform. During adulthood, most of the cell does not duplicate except some cells continue to divide to replace the old or damaged cell in blood, skin and intestine. This growth is very controlled and no excessive cell growth takes place. But sometimes when a mutation occurs in one or more genes which causes unnecessary cell reproduction and as a conclusion, there is no control over the growth of cells. It is called malignant transformation and this is the starting of cancer (Hosick et al., 2015). There are many different types of cancer but the early stage diagnosis

Some types of cancer are more aggressive that others, and some are more easily treated and managed if diagnosed in early stages, however there is no known cure for cancer. Malignant tumours can spread into tissue that is nearby. When malignant tumours are removed they can sometimes grow back. Benign tumours do not spread into nearby tissues.

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 are many kinds of cancer, but they all start because of out-of-control growth of abnormal cell (American Cancer Society, 2010).

First, we must understand what cancer is and how it forms, cancer is “a malignant and invasive growth or tumor, especially one originating in epithelium, tending to recur after excision and to metastasize to other sites.”1 it is when normal cells mutate and begin to reproduce at such an accelerated rate that body does not have time to get rid of these bad cells and a mass begins to grow creating a problem for the body.

There are a wide variety of cancer types. They all have several things in common, however. Each cancer starts with cells that become abnormal or cancerous. These cells reproduce and form a mass of cancerous cells. This mass is called a tumor. When the cancerous cells spread, or metastasize, they can impact other tissues, organs, and systems of the body. A second commonality among cancers is that when they are detected early, they are easier to treat and the treatments are more likely to work. In many cases, a cancer that is caught early can be completely destroyed.

“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 has been an ongoing controversy on what can help to prevent getting it. Cancer is when cells are dividing at an uncontrollable rate. Cancer is developed when cancer cells go into lymph nodes and also when they take over the blood vessels, lymph nodes are when there is swelling the the lymphatic system. With the cancer there is swelling which is called a tumor. Tumor is when there is swelling in the part of the body that is not caused by inflammation, but is caused by a large group of abnormal tissue cells. There are two different types of tumors. There is the malignant tumor which is a tumor that can be cancerous which is when the cells divide at a faster rate, and can also take over tissues. The other tumor is a benign tumor, which is a noncancerous and could be removed, and it cannot take over any near tissues. Genes play a big role in cancer itself. Cancer happens when a gene is mutated and changed, and when the gene becomes mutated it becomes abnormal. Because it is not a normal cell, its a mutated cell which makes it more cancerous. One gene that is a cancerous cell is a proto-oncogene which is a normal gene, but if it is mutated or changed it becomes a oncogene which is then now a cancerous cell and then divides into multiple different cancerous cells that can affect one 's body. The proto-oncogene can escalate if mutated into a cancerous cell. Which

Cancer is when abnormal cells divide in an uncontrolled way and develops when the body’s normal control mechanism stops working. Cancer cells are different than normal cells in many ways that allow them to develop out of control and become invasive. Normal cells mature into distinct cell types with particular functions and cancer cells do not. Unlike normal cells, cancer cells continue to divide without stopping. Many cancers form solid tumors, which are masses of tissue. Tumors can be malignant or benign. Unlike malignant tumors, benign tumors do not invade tissues that are near. Cancerous tumors are malignant, which means these tumors invade tissues. A cancer that has spread from where it started to other places in the body is called metastatic cancer. The process is called metastasis. Treatment may help prolong the lives of some people with metastatic cancer.

There are more than 100 types of cancer and are named after the organs or tissues where the cancers form, but they may also be described by the type of cell that formed them.

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.
