Cancer: The Virulent Disease Essay

1094 words - 4 pages

An ordinary human body contains approximately one trillion cells and precisely 46 chromosomes in each cell. However, the human body can be altered by a genetic mutation. Over the course of history, genetic mutations have had a large impact on the human race. They have brought harm to numerous amounts of people. Cancer, in particular, is one of the most lethal diseases. Cancer begins when a portion of DNA inside a chromosome is damaged, causing a cell to mutate. Then, the mutated cell reproduces multiple times and creates a tumor. Afterwards, cancer cells break off of the tumor, enter the bloodstream, and disperse throughout the body. If the cells break off, the tumor is considered malignant - this type of cancer is very difficult to cure. Many patients today stay optimistic for a medication to heal cancer. It is imperative to address a few of the causes and effects of cancer in order to gain a general knowledge of genetic mutations.

To begin, people can receive certain forms of cancer if they use tobacco products. When discussing health problems of smoking, the author writes, “Smoking harms nearly every organ in the body” (Harms of Smoking and Health Benefits of Quitting). Scientists have conducted research and have concluded that using a tobacco product damages cells. The damaged cells become mutated and form cancer cells. The author goes on to explain, “Among the 250 known harmful chemicals in tobacco smoke, at least 69 can cause cancer” (Harms of Smoking and Health Benefits of Quitting). These harmful chemicals are catalysts for many types of cancer. Some of these toxins include arsenic, carbon monoxide, and lead. When directly consumed, these chemicals are very pernicious, so it is obvious that they can cause diseases like cancer. In another online article, the text states, “Certain chemicals in tobacco smoke damage an important gene called p53. The p53 gene is found in the nucleus of every cell in the human body and its main role is to prevent cancer cells evolving” (Does Smoking Cause Cancer?). The poisonous chemicals in cigarettes weaken a gene that protects the body from receiving cancer. Without the p53 gene, people become more susceptible to this harmful disease. In order to prevent cancer, society must learn to not use tobacco products.

Furthermore, having an unhealthy diet provokes cancer. When explaining foods that increase the risk of cancer, the author writes, “Certain chemicals are made when red and processed meats are cooked at high temperatures, such as on a barbecue. These chemicals can damage our cells, making them more likely to become cancerous” (Diet Causing Cancer). Cooking processed meat at a high temperature can create noxious chemicals. If one consumes this type of meat, it is like he/she is smoking a cigarette. The poisonous toxins in the meat infiltrate the body and alter the structure of cells, causing the cells to be cancerous. The author goes on to declare, “Overweight or obese people have an increased risk...
