Lately, there have been casesspread of a disease such as intestinal cancer, the symptoms of which do not appear for a long period of time. Intestinal cancer is a group of tumors that form in the large intestine or rectum from their epithelium, and occurs most often in men over the age of forty.
Causes of cancer in the intestinethe present day is practically not studied, it is assumed that there are some factors that provoke the appearance of cancer. These factors include:
1. Heredity. In medicine, cases of intestinal cancer and diffuse polyposis of several members of the family are known. In this case polyposis is characterized by the formation of benign tumors that degenerate into cancer due to a genetic mutation inherited.
2. Chronic inflammatory processes in the body. This includes diseases such as ulcerative colitis, proctitis, Crohn's disease, anal fissures.
3. Improper diet. With an overabundance of fatty, meaty and fiber-rich food and a lack of vegetables and cereals in the diet, as well as a sedentary lifestyle, the risk of cancer develops.
4. Excessive smoking and alcoholism. These factors most often cause chronic diseases of the gastrointestinal tract, which can develop into a cancerous disease.
It is generally accepted that bowel cancer symptoms do notexhibits a long period of time, but often there may be a presence of blood in the stool, constipation or diarrhea. If these symptoms persist for more than two weeks, you should contact a medical facility to undergo examination, because the disease is in its early stages is almost always curable.
Other bowel cancer symptoms are such asbloating, pain or discomfort in the anus, nausea or vomiting. Although these symptoms are rare, they should be taken into consideration when diagnosing the disease. If the disease is at the last stages of its development, a person can have constant pain in the abdomen, inflammation of the bladder, which gradually spreads to the ureters and kidneys, the excretion of urine during defecation.
Depending on how far the disease spread, it is common to distinguish four stages of intestinal cancer:
1. 0 stage - a cancer tumor of small size, it does not extend to other organs and tissues.
2. I stage. The tumor spreads through the intestines, not reaching the muscle layer.
3. II stage. Cancer spreads to the inner, muscular and outer layers of the intestine.
4. Stage III. A malignant tumor from the intestine spreads to the lymph nodes located nearby. It can be said that intestinal cancer, stage 3 of its development, is characterized by an increase in lymph nodes, while survival rate is 50%.
5. IV stage. The tumor extends to other organs and tissues of the body. Most often, metastases are observed in the liver, lungs and ovaries. Thus, intestinal cancer, stage 4 of its development, in particular, is characterized by a low survival rate, only 1% of people continue to live for five years, in all other cases a lethal outcome is observed.
Diagnosis of bowel cancer is carried out with the help of colonoscopy, sigmoidoscopy, irrigoscopy, fibrocolonoscopy, and also studies of feces are conducted.
Thus, intestinal cancer, the symptoms of whichdescribed above, treatment involves surgery and radio and chemotherapy. With immediate treatment in the early stages of the disease, it is possible to achieve a 100% cure of the disease.</ p>
