DNA Replicaiton Cause Cancer Essay

The origin of cancer within a person could be a result of multiple variables. Cancer could simply be a malfunction within the body. All living things are composed of cells. Cells house the genetic makeup of a person: deoxyribonucleic acid, or DNA. The human body is composed of trillions of cells which constantly divide to replace old or damaged cells (“The Cells”). For cells to divide, enzymes within the cell must duplicate the DNA. Mistakes in copying genetic code are common. This division of cells usually occurs in a consistent and controllable manner as the cell has the ability to check its DNA for errors and self-destruct if an error is potentially harmful; however, not all mistakes are caught. If the mistake in the DNA is not noticed and taken care of, the cell can develop and begin to behave abnormally. It may gain the ability to stimulate its own growth and ignore signals to stop. When this happens, a cluster of abnormal

Smoking added to excessive alcohol consumption increases the risk of these cancers even more. A maximum of four drinks a day for men and two drinks for women is recommended. Surprisingly enough, frequent consumption of smoked cured and nitrate preserved meats has also been shown to cause cancer. The codes of 249, 250, 251, and 252 on labels of corned beef, bacon, and smoked sausage indicate that the meat has been cured or preserved. These products increase the risk of stomach cancer and should be eaten in moderation. (http://www.petermac.unimelb.edu.au/DIET.html)

There are several reasons that someone could become diagnosed with cancer, a couple examples being smoking and their eating habits. Things like pig meat and beef using in hot dogs, bacon, burgers and so on are linked to 18 percent of deaths by cancer. It’s been proven that chemicals that are added to these meats are the reason for the link with cancer. There are 800 studies that went on from a group of 22 scientist from IARC trying to find this direct link between cancer and meat. According to Associated Press, “Based on that analysis, the IARC classified processed meat as cancer-causing, noticing links in particular to colon cancer, but also stomach cancer.”

“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

Cancer is the main cause of death in the world, estimating 8.2 million fatalities in 2012 alone

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

Explain/say more: Nobody knows what actually causes cancer but lifestyle, exposure to harmful chemicals, diet, infections, and even genes are considered factors that can affect a person's risk of getting cancer.

The causes of cancer are complex. It may be caused by a variety of things, including your genetic make-up and lifestyle choices, such as smoking. But having a risk factor, or even many risk factors, does not mean that one may suffer from the disease. And there are cases, who developed the diseases with few or no known risk factors.Several factors can affect a person’s chance of getting cancer of the pancreas. Most of these are risk factors for exocrine pancreatic cancer.

Cancer has been one of the biggest killers in the world for the past 100 years. Previously, before science advanced to the point that it’s at today; no one really understand where cancer came from or why it would suddenly generate inside a human’s body. But, since finding out the reasons behind all of the hundreds of different cancers, there’s almost always a cause/health defect.

Cancer is a leading cause of death and devastating experiences for patients’ family members and close friends. The disease undermines the emotional wellbeing of the survivors during and after treatment. It often affects the physical appearance and exposes the family members to financial constraints thereby leading to depression, reduced productivity at workplaces and many other social problems. However, the controversies over the causes of cancer continue to impact the awareness campaigns and the general population attitude towards treatment options. According to Thun, Linet, Cerhan, Haiman, and Schottenfeld (2017), many people believe that gene composition is the leading risk factor for cancer. In contrast, etiological studies have confirmed

There are many ways that you can get cancer. You can get cancer from smoking, sunlight, your diet, mold, viruses, and inheritance. Out of those factors, the most common cause of cancer today is smoking. All cancers are genetic because they are caused by the mutations that happen to the gene. Some common cancers that are

Cancer occurrs by the production of multiple mutations in a single cell that causes it to proliferate out of control. Cancer cells often different from their normal neighbors by a host of specific phenotypic changes, such as rapid division rate, invasion of new cellular territories, high metabolic rate, and altered shape. Some of those mutations may be transmitted from the parents through the germ line. Others arise de novo in the somatic cell lineage of a particular cell. Cancer-promoting mutations can be identified in a variety of ways. They can be cloned and studied to learn how they can be controlled.

The process of DNA replication plays a crucial role in providing genetic continuity from one generation to the next. Knowledge of the structure of DNA began with the discovery of nucleic acids in 1869. In 1952, an accurate model of the DNA molecule was presented, thanks to the work of Rosalind Franklin, James Watson, and Francis Crick. To reproduce, a cell must copy and transmit its genetic information (DNA) to all of its progeny. To do so, DNA replicates following the process of semi-conservative replication. Two strands of DNA are obtained from one, having produced two daughter molecules that are identical to one another and to the parent molecule. This essay reviews the three stages
