Colon Cancer - Sign and Symptoms

What is cancer?
Cancer is a group of more than 100 different diseases. They affect the body's basic unit of the cell. Cancer occurs when cells become abnormal and divide without control or order. Like all other organs of the body, large intestine (colon) and rectum (rectum) is composed of many types of cells. Normally, cells divide to produce more cells only when the body needs them. Orderly process to help keep us healthy.
If a cell continues to divide when new cells are not needed, a mass of tissue formed. This mass of extra tissue, called a growth or tumor, can be friendly (not harmful) or malignant (harmful).
Friendly tumors are not cancer. They can usually be removed and, in many cases, they do not arise again. Most important, cells from tumor-friendly tumors do not spread to other parts of the body. These tumors are rarely a threat to friendly lives.
Malignant tumors are cancer. Cancer cells can invade and damage tissues and organs near the tumor. Also, cancer cells can break off and get out of a malignant tumor and enter the bloodstream or lymphatic system. This is how cancer spreads from the primary tumor to form new tumors in other parts of the body. The spread of tumors is called metastasis.
When cancer spreads to other parts of the body, the new tumor has the same kind of abnormal cells and the same name as the primary cancer. For example, if colon cancer spreads to the liver, the cancer cells in the liver are cells of colon cancer. The disease is colon cancer that has spread (metastatic colon cancer), so he instead liver cancer.

Definition of Bowel Cancer (Colon) and Rectum Cancer (rectum)
The colon is part of the digestive system (digestive system) where the material that is discarded (waste) is stored. Rectum (rectum) is the tip of the colon near the rectum (anus). Together, they form a long, muscular tube called the large intestine. Tumors of the colon and rectum are growths which come from the inner wall of the colon. Friendly tumors of the colon called polyps (polyps). Malignant tumors of the large intestine are called cancers. Friendly polyps do not invade adjacent tissue or spread to other parts of the body. Friendly polyps can be easily removed during colonoscopy and are not a threat to life. If polyps are not friendly removed from the colon, they can become malignant (cancerous) over time. Most of the cancer, colon cancer is believed to have developed from polyps. Colon and rectal cancer, also referred to as colorectal cancer (colorectal cancer), can invade and damage tissues and organs nearby. Cancer cells can also break off and go out and spread to other parts of the body (such as liver and lung) where new tumors form. Colon cancer spread to organs far away from it is called metastasis of colon cancer. Once metastasis has occurred in colorectal cancer (colorectal cancer), a full healing of cancer is not possible.
Globally, cancer of the colon and rectum are the third leading cause of cancer in men and fourth leading cause of cancer in women. The frequency of koloretal cancer varies around the world. He is common in the western world and is rare in Asia and Africa. In countries where people have adopted western diets, the incidence of colorectal cancer increases.
What causes colon cancer
Doctors believe that colorectal cancer is not contagious (a person can not get the disease from a cancer patient). Some people are more likely to develop colorectal cancer than others. Factors that increase a person's risk of colorectal cancer include high fat intake, a family history of colorectal cancer and polyps, the presence of polyps in the colon, and ulcerative colitis due to a chronic (chronic ulcerative colitis).
Diet (Food) and colon cancer
Diets high in fat are believed to affect (the tendency to give) in human colorectal cancers. In countries with colorectal cancer rates are high, the fat intake by the population is much higher than in countries with cancer rates are low. It is believed that the breakdown products (breakdown) of fat metabolism lead to the formation of chemicals that cause cancer (carcinogens). Diets high vegetables and foods high in fiber like the loaves of whole-grain and wheat-wheat can cleanse the bowel of these carcinogens and help reduce the risk of cancer. Colon polyps and colon cancer
Doctors believe that most colon cancers develop in colon polyps. Therefore, removing polyps benign colon can prevent colorectal cancers. Colon polyps develop when chromosome damage occurs in cells in the lining of the colon. Chromosomes contain genetic information inherited from each parent. In normal, healthy chromosomes control the growth of cells in an orderly manner. When chromosomes are damaged, cell growth becomes uncontrolled, resulting in masses of extra tissue (polyps). Colon polyps are initially friendly (is good). Through the years, colon polyps that Friendly can obtain additional chromosome damage to become cancerous.
