Why Cancer Is Not Contributing With Onespecific Factor

Cancer can be caused by many factors. Some of these factors include: Genetics, Tobacco, Diet, Physical Activity, Sun Exposure, Radiation, and Other Carcinogens. Some types of cancer run in certain families, but most cancers are not clearly linked to the genes we inherit from our parents. Most people are unaware about just how much tobacco use accounts for of cancer related deaths. Even though cigarette use has decreased significantly there are still tobacco products that are highly popular. Vape pens, or electronic cigarettes are on the rise among former smokers and teenagers. Although believed to be healthier there is still nicotine, and unknown substances in the flavored liquid. Many people are also very unprepared when it comes to being outside for prolonged periods of time. Sunscreen is a necessity in order to protect oneself from the harmful UV rays. It is also very important to have regular checkups from a

- There are different kinds of Cancers that can be caused by many different factors.

Cells are very smart, they don’t let anything just get inside them. Scientists have to find away to get the cure into the cells without the cell rejecting it. Scientists don't really have a clear understanding of what cancer is, how people get it, or how they can prevent it. In result, it is hard to find a cure. Although there are many cures to cancer they are not all guaranteed to kill the cancer.

In order to properly understand this cancerous condition, this question must first be addressed: what is cancer? Generally, cancer is when cells in the body begin growing out of control. Instead of dying when they are supposed to, the cancer cells continue to grow in size as well as produce more

A silent killer of today is cancer; there are many different forms of cancer. For each different style of cancer, there are many unanswered questions about cancer, even if most of them are currently unknown to us. Cancer is a debilitating and often fatal disease, but thanks to current medical research, knowing the causes, recognizing the symptoms, and planning the treatments have become much easier.

Often researches and doctors focus on established views of why cancer develops and what can be done to control it. This article highlights how a change in understanding can lead to some of the biggest advances in cancer screening and treatment. Here’s how TED is rethinking cancer: https://www.ted.com/read/ted-studies/medicine/introductory-essay

The early theories of cancer and its origin were different between each other throughout the history.

One might ask, what is the point of living healthy? Even though, random mistakes are enough to cause cancer alone sometimes. However, in other cases a mix of random mistakes, blunders of environmental factors and unhealthy life style, Will turns the cell into cancers, Vogelstein said. However, according to Live Science 42 percent of cancers could be prevented with changes to person’s life

“The Emperor of All Maladies” captured the whole essence of cancer. This book gave a very good narrative of the historical record of cancer, the scientists and important public figures who contributed to the fight against a disease that has so much caused despair, pain, disfiguring of the body and worst of all, death. Cancer is seen as the abnormal growth of cells. A normal cell becomes cancerous when there is a defect in the regulation of its growth. Cancerous cells also tend to be elusive and resistant to treatments. Numerous attempts have been channeled into demystifying the nature of cancer. Some of these attempts proved abortive while a few served as a harbinger of hope. Cancer have proved to be part of our genetic makeup, hence, total eradication of it remains a future accomplishment.

The article begins by introducing us to the early studies and theories proposed in the 1960’s on cancer. Peter Duesberg gives us the process of which he and other researchers went through to see how cancer works. During his study of cancer in the 1960’s he believed that cancer (in most forms) were caused by viruses. He and his colleagues began to go further into this idea by researching on a virus called avian Rous sarcoma. They managed to isolate a gene within the virus called src that caused the virus to make tumors. In later years they discovered that this gene was already present in an organism’s DNA. This discovery proposed a new theory. There must be a mutation or trigger that happened in our very own versions of src to cause cancer.

In our body we have trillions of cells that have different functions. All parts of the body, organs, muscles, skin, and even bones and blood are composed of these cells. Cells are constantly growing and multiplying to replace old damaged cells. Cancer starts in our cells that are tiny building blocks that make up the organs and tissues of our body. Each cell has a controlled center called a nucleus. The nucleus receives signals from the body to say when the cells should divide and grow and when they should stop. These molecules can work inside the cells or on their surface. The nucleus then tells the cell what to do. Usually cells divide in a controlled way to make new cells, they eventually die and then the body sends a signal to the cell to repeat the process. When cancer is present, the cells do not get these signals from the body, therefore the cells keep dividing and make more and more abnormal cells. These cells form excess tissue or lump called a tumor. These tumors invade and destroy surrounding tissues and nearby organs. Eventually cancer cells break off and spread through the blood to form new tumors in other parts of the body. This process is called Metastasis and it can be a slow process occurring over a number of years, or can happen rapidly within a few weeks. Cancer harms a person in two ways by physically blocking or pressing organs, and by reproducing instead of normal healthy cells. The cancer can cause pain and illness by pressing against nerves or blocking nearby

After reading this chapter, I learned about cancer such as the different types of cancer that exist. People consider cancer as a terminal illness but each type of cancer has its own risks, treatments and diagnostics. While I was reading this chapter, I realized that cancer cells are known as abnormal cells that can divide and may invade other tissues. I discovered the risk factors for cancer, some cancers occur without identified reasons and are more difficult to avoid other cancers with known risk factors are produced in the absence of the risk factor. After reading this chapter, I recognized that the cancer is known as the second leading cause of death in the United States, cancer is not a disease,

Cancer can be caused by a plethora of things, i.e. mutation through viruses, chemical or radiations, carcinogens. Mutation, a type of evolution, is any change in the nucleotide sequence of a cell’s DNA (Reece 199), this may come about by having a virus, exposure to certain chemicals and radiation, after the mutation, there is no reversing it and hence can be transferred genetically to any children. A carcinogen defined by Encyclopedia Britannica is, “any of a number of agents that can cause cancer in humans,” which leads to mutation. After

From the earliest times, physicians have had a had time understanding the causes of cancer. Ancient Egyptians blamed cancers on the gods.Hippocrates believed that the body had four humors which are body fluids. These four humors are blood, phlegm, yellow bile, and black bile. It was believed when the humors were balanced, a person was healthy. The belief was that too much or too little of any of the humors caused disease. It couldn't really be tested because during that period religion prohibited

Cancer is a disease of cells that are the main body unit. Our bodies are constantly making new cells to allow us to grow, to replace worn-out cells or to recover the damaged cells after injury. Certain genes control the process all types of cancer are caused by damage to these genes. This damage usually occurs during our lifetime, although few people inherit a damaged gene from a parent. Normally, cells grow and multiply in the correct way. However, damaged genes can cause their abnormal behavior. They can develop into a lump called a
