Colon Cancer Essay

Colon and rectum are both located in the digestive system. There are two parts of the digestive system. Upper part of the digestive system included stomach and small intestine, in which their job is to digest food for energy. Lower part of the digestive system are called gastrointestinal system, where colon and rectum are located. Its function is to absorb fluid to form solid waste then passes from the body as a stool. Small intestine made up of the most part of the digestive system, it is about 20 feet long. It break down the foods and absorb most of the nutrients. Then it pass to the large intestine which is mainly made up of a muscular tube, colon, and it is about 5 feet long. The colon can be divided into 4 section. Ascending colon, it is the beginning of the colon that included the cecum, where the appendix attaches to the colon. Transverse colon, the second section of the colon. It located in the upper abdomen and from the right to the left. The next section is called descending colon, the lower abdomen and from the left to right. The last section,

The large intestines are a part of the digestive system (Colorectal cancer, 2015). The large intestines (large bowels) are made up of the colon and the rectum (What is colorectal cancer, 2016). The colon is five feet long muscular tube that makes up the majority of the large bowel (What is colorectal cancer, 2016). After food goes through the small intestines, of the digestive system, the colon absorbs the salt and water from the food that remains and the waste matter (feces) is the byproduct (What is colorectal cancer, 2016). The feces is then expelled from the body through the anus (What is colorectal cancer, 2016).

Squamous cell carcinomas cancer is the most common colon cancer in the United States. It is located within the anal canal and around its walls. This sparks my interest because it is quite odd to me that cancer could occur in the anal canal or outside of it. It really shows how cancer can literally occur anywhere in the body. Even Though it is located in the anal canal, the cause of colorectal cancer is usually due to many other reasons that has nothing to do with the colon itself. These causes are the amount of exercise a person have, any smoking or drinking, even if the person is overweight, or attaining HPV. There are also many causes that can not be changed by your lifestyle, for example if you have the genes to have colorectal cancer or

In 2015, 132,700 people will be diagnosed with colorectal cancer (CRC) and 49,700 people will die from the disease (ACS, 2015). According to the CDC, 1 in 30 cases of colorectal cancer can be attributed to Lynch syndrome (CDC, 2015). Using figures from 2015, that would be 3,981 new colorectal diagnoses related to Lynch syndrome. Livstone (2014) states, “Patients with one of several known mutations have a 70 to 80% lifetime risk of developing CRC”.

Colon cancer has an excellent prognosis when diagnosed early, with 92 percent of patients living longer than five years who were diagnosed during Stage 1. Preventing colon cancer through a healthy diet and getting regular colonoscopies is crucial in diagnosing the cancer at an early stage.

According to Mayo Clinic, one of the most prevalent cancers in the United States is colon cancer. An additional 100,000 Americans will contract colon cancer ever year with half of the cases ending in death. The American Cancer Society (ACS) says that over 90 percent of colon cancer occurs in adults over 50 years of age.

Colon cancer is considered as the second killer cancer in United States and Western Europe (1). Moreover, in the U.S it is the third common cancer ,and the risk is about 6 percent(1).It mostly affects elderly men and women, and the risk to the people who are African-Americans higher (1). Moreover, a personal history or family history makes the risk greater and the lifestyle effects too (1). For example, if the person overweight or suffers from obesity, that makes him under the risk. However, what is the Colon cancer?, and why is it a deadly disease ?.This will present in this essay based on a definition of colon cancer and its symptoms, screening, treatment.

Cells in almost any part of the human body can turn into cancer and can

When eating a meal the gallbladder then contracts which sends bile to the small intestine. Then the nutrients gets absorbed into the blood stream, there is leftover liquid that passes into the small intestate. What food that is left over then travels to the large intestine. “The large intestine is a 5-6 foot long muscular tube that connects the cecum which is the first part of the large intestine to the rectum and the last part of the large intestine”. The large intestine is made up of the cecum, which is the ascending right colon, the transverse colon, the descending colon, and the sigmoid colon, that connects to the rectum. Stool, or waste left over from the digestive process, is passed through the colon by means of peristalsis, first in a liquid state and ultimately in solid form as the water is removed from the stool. A stool is stored in the sigmoid colon until there is a movement to release the stool into the rectum twice a day. When the descending colon becomes full it then empties the contents into the rectum. The rectum is an 8 inch chamber that connects the colon to the

Cancer is a class of diseases characterized by out-of-control cell growth. Colon cancer forms when this uncontrolled cell growth happens in the cells of the large intestine. Most colon cancers originate from small, noncancerous (benign) tumors called adenomatous polyps that form on the inner walls of the large intestine. Some of these polyps may grow into malignant colon cancers over time if they are not removed during colonoscopy - a procedure looking at the inner lining of the intestine. Colon cancer cells will invade and damage healthy tissue that is near the tumor, causing many complications. After malignant tumors form, the cancerous cells may travel through the blood and lymph systems, spreading to other parts of the body. These

The immune system has a way of detecting and destroying cells that are abnormal, which can cause cancer in the human body. In most rare cases some cancers are able to avoid the detection in the immune system. Colorectal cancer (CRC) is also known as colon cancer, it is part of the digestive system that is called the gastrointestinal system. It occurs in the large intestines that are located in the lower part of digestive system. Colon cancer usually starts small adenomatous polyps, which are noncancerous clumps of cell (Mayo clinic 2013). As time progress these small adenomatous polyps will eventually become colon cancer. The granulocytes colony stimulating factor (G-CSF) it occurs mostly in human and mouse CRC. In humans

The digestive tract starts in the mouth and then goes to the pharynx. Then goes to the esophagus. Then from the esophagus then to the stomach. From the stomach it goes to the small intestines. Where the food is broke down using the enzymes of the pancreas and bile from the liver. Then thru the colon and the rectum and then out the

The Digestive System is like tubes that convert food into body fuel. These tube-like organs are about thirty feet long. It begins at your mouth and ends in the anus. Once food enters your mouth the Digestive system has already began. It first is broken down by saliva and passed down your esophagus and into your stomach. There, it’s broken down into proteins, carbohydrates, fats, vitamins and minerals. After it is broken down, the Small Intestine is in charge of passing nutrients into the blood stream and into the liver. Anything that is left (waste) passes into the large intestine. The waste is eaten by harmless bacteria and dead cells, which forms feces and is let out every time you use the

Preliminary data from the Royal Marsden Hospital have shown that, in patients with poor-risk rectal cancer,

Colorectal cancer mainly starts at colon or the rectum. They are common in most of the way like features, but they have different treatment. What is the different between colon cancer and rectal cancer? Colon cancer happens first four to five feet of the large intestine and rectal cancer happens in the last few inches of the large intestine where it is connected to anus. (cancercenter.com)
