Rectal cancer

What is rectal cancer?

Two-thirds of total colon tumors account for tumor of the rectum. The rectum (15-20 cm) - the last section of the colon - end outer opening of the anus. Typically, rectal cancer arises from intestinal polyps. However, cancer does not develop in all kinds of polyps, but only from those on the surface of which a large number of blood vessels, or cilia. Rectal cancer affects both men and women. Most often the disease occurs in people 50-70 years.

Symptoms of rectal cancer

  • Bloating, abdominal pain.
  • Blood and mucus in the stool.
  • Violations of the bowel (persistent diarrhea followed by constipation).
  • Exhaustion, fatigue.
  • Decrease in body weight.
  • Pain in the rectum, itching, and colic.

Causes of rectal cancer

The causes of rectal cancer are not fully clarified. It was noted that in some countries the incidence of rectal cancer is very low. It is proved that the greatest influence on the occurrence of this disease has malnutrition. The most common cause is the use of a large number of foods low in ballast (fibrous substances). In addition, it is assumed that the development of rectal cancer is largely due to an unlimited consumption of protein and fat of animal origin.

Treatment of rectal cancer

The only method to successfully treat rectal cancer - surgery. As with other cancers, early diagnosis and prompt surgical intervention is the key to successful treatment. Often, after such an operation, the patient forms an artificial anus. Another method of treatment sometimes used to improve the operational method - radiation therapy. Chemotherapy is not yet effective in the treatment of this cancer.

How to help yourself? An important preventive measure for colon cancer is nutrition. It should limit the use of animal protein, food rich in favor of ballast (fibrous) materials. Early symptom of rectal cancer is blood in feces. Although much more often the cause of such bleeding is hemorrhoids. After identifying the hemorrhoids are advised to regularly visit a doctor.

In addition to blood in the stool, there may be other symptoms such as fatigue, exhaustion, anemia. When these symptoms occur, you should seek medical advice.

Rectum can be viewed during the so-called rectoscopy. With proctoscope produce biopsy-fence small amount of tissue for research. A more comprehensive medical examination is examination of the entire colon (colonoscopy). To detect internal bleeding apply simple methods of testing.

Course of the disease

For reasons not yet clarified there is a degeneration of cells of the mucous membrane of the colon and form a malignant tumor. If you remove the entire tumor, the patient usually recovers. Much worse is the case in the event that the tumor has already spread (metastasize), the likelihood of recovery is 5-10%.

Blood in stool is often a symptom of hemorrhoids. However, this may be a sign of rectal cancer, so you should consult a doctor to determine the cause of bleeding.

Disease of civilization

Rectal cancer and colon cancer are very serious diseases. This is one of the most common forms of malignant human tumors. In most European countries, rectal cancer and colon cancer is second only to lung cancer.
