- Colon cancer: creeps imperceptibly
- As revealed
This type of cancer develops in the large intestine - the lower part of the digestive system. In order to detect colon cancer as early as possible, it is recommended to undergo regular medical examinations on a regular basis.
Signs and cancer symptoms symptoms of cancer: time to recognize the disease - guarantee of recovery colon:
- changes of intestinal motility, including diarrhea or constipation or a change in stool consistency;Rectal bleeding or the presence of blood in the stool;
- Constant discomfort in the abdominal cavity, for example, convulsions, increased gas or pain;
- Feeling that the patient can never fully empty the intestines;
- Weakness or fatigue;
- Weight reduction.
In the early stages of colon cancer rarely causes symptoms. When the symptoms appear, they may depend on the size and location of the tumor in the large intestine.
In most cases, determine the cause of colon cancer is not po
- education Precancerous colon
Colon cancer usually begins with the appearance of clusters of precancerous cells( polyps) on the inner shell of the colon. Some polyps have the form of fungi, others - flat or ingrown into the walls of the intestine. Removal of polyps before they become cancers can prevent colon cancer.
- Inherited gene mutations that increase the risk of developing colon cancer
Some inherited genetic mutations increase the risk of developing colon cancer, although they are associated with only a small number of cancer cases. The presence of these mutations does not make the disease cancer inevitable, but they can significantly increase the risk of its development.
Family adenomatous polyposis is a rare disorder in which thousands of polyps appear on the walls of the large intestine. In the absence of treatment in people with this disorder at the age of forty, the likelihood of developing colon cancer is significantly increased. Hereditary nonpolyposis colorectal cancer, also called Lynch syndrome, increases the risk of developing colon cancer and other cancers. People with this disorder tend to develop colon cancer at the age of up to fifty years.
Both these violations can be detected by genetic testing. If your family history has colon cancer or other cancers, discuss with your doctor the possibility of doing so.
Factors that may increase the risk of developing colon cancer:
- Age. About 90% of patients diagnosed with colon cancer are over fifty years old. Colon cancer can also develop in young people, but this happens much less often.
- Inflammatory bowel disease. Chronic inflammatory bowel disease Inflammatory bowel disease: symptoms and treatment , such as ulcerative colitis Colitis - a dangerous colon lesion and Crohn's disease may increase the risk of developing colon cancer.
- Colon cancer or polyps of the large intestine in a family history. The diet is low in fiber and high in fat. Cancer of the colon can be associated with eating habits. Studies in this area give mixed results. Some studies have shown that regular consumption of red meat is also associated with an increased risk of developing colon cancer.
- Sedentary lifestyle.
- Obesity. People with obesity are not only more likely to develop cancer of the colon, but more often than people with normal weight, they die from it.
- Alcohol abuse.
- Radiotherapy. In people who have ever undergone radiotherapy Radiotherapy in cancer treatment: irradiation to help , the risk of developing colon cancer is higher than that of others.
If you suspect a colon cancer, the following diagnostic methods are used:
- Blood test;
- A barium enema is a procedure that allows physicians to examine the entire large intestine using an X-ray. Barium, a contrasting coloring substance, is injected into the intestines with an enema. It covers the inner shell of the intestine, allowing you to clearly see the silhouette of the rectum, large intestine, and parts of the small intestine;
- Computed tomography.
If colon cancer is diagnosed, it is necessary to establish its stage. For this, computed tomography or other methods of medical imaging are used.
