Still is not definitive that one has to do with cancer. There are plenty of Causes whereby blood is mixed with the droppings. A microscopic examination and colonoscopy can inconclusive. However, the blood may come from in a number of cases stomach or bowel cancer.

Adenocarcinoma

Ulcer- and colon cancer occurs predominantly in patients, who are older than 40 year. Again, men run a greater risk than women. The number of patients increases with increasing age, especially after the fiftieth year.

Gastric cancer clearly shows, that elimination of external harmful influences the growth of carcinomas inhibits. In all western industrialized countries, the number of gastric tumors in the last thirty years, the course dropped significantly, partly because the addition of carcinogenic substances in the food was banned. In the United States there has even been a reduction in 50 %. However, the number of intestinal tumors remained at the same level of.

Benign and malignant tumors present themselves with a distinct discomfort in the stomach area, a sensation of pressure, rarely pain. These signs occur immediately or some time after the meal. The stool is alternating thin or too dry and too hard. The appetite disappears. Certain foods (especially meat) arouses strong reluctance on.

In the early stages is rare blood loss. Radiographs are often not sufficient to establish a clear diagnosis. Here, too, optical examination of the stomach can be clarifying and facilitate the reduction of diseased cells for a cytological examination. This study is called gastroscopy. In the devices connected to the stomach in the duodenum and small intestine are rare long carcinomas. They usually develop in the dikke Darma, in 70 % of the cases in the rectum and the descending part of the colon. For the diagnosis of the latter tumors, the doctor may by stabbing a finger into the rectum to feel the tumor. The tumor is too high, then one has to rectoscopy (a study of an instrument with a light) perform.

Tumors of the digestive organs with the modern research methods to detect lung cancer than more readily. Operations performed on time delivery also decided more success. Thans wordt in 60 % of cases with a survival rate of more than 5 counted years.

Healing is possible only after surgery. These are in addition to the malignant also possibly present in benign tumors removed, so that they can not degenerate. The stomach or intestine by this intervention smaller (ulcer- of darmresectie; resect = cut away). After a certain period, diet they function in the rule again full. Are the deep tumors in the rectum, making this organ must be removed, then an artificial anus (old preternatural) applied. After opening the abdominal cavity, a loop of the colon is pulled forward and lateral to the peritoneum sewn. After at most 1 to 3 days shall said opening for the faeces to be released. In favorable conditions the normal anus can be opened again after some time, wherein the anus, of course, is removed praeternaturalis.

Polyps

In the colon and rectum often come, especially in older men, benign, but prone to bleeding pedunculated growths for. These polyps can become cancerous. Sometimes they are small as a pinhead, but sometimes as large as nuts.

& Nbsp;

Hereditary polyposis

In some families there is a genetic predisposition for these polyps, which then occur in large quantities and also in younger people and even children are observed. Enlarged mucus secretion, diarrhea, severe pain and intestinal bleeding are the symptoms, which are confirmed by radiographs and intestine mirroring. In many cases it is advisable to remove the polyps surgically, before they degenerate to carcinomas.

Cancer of the large intestine

Carcinomas or colorectal cancer are found in all parts of the large intestine, but especially in the rising and subsequent section. The first symptoms are usually not characteristic: suddenly altered defecation, constipation alternating with diarrhea, blood in the stool, which is often attributed to hemorrhoids. If these symptoms do not disappear, and no cause to designate, An overhaul, possibly followed by surgery, necessary.
