What are the symptoms of bowel cancer? What causes bowel cancer? On what basis?

Bowel cancer has a lot to do with one's dietary habits, and long-term use of foods with high salt content, pickled foods, overnight dishes, etc., can easily induce intestinal lesions, which in turn can lead to bowel cancer. Bowel cancer generally occurs in middle-aged and elderly people, and is induced by long-term poor eating habits. Bowel cancer can cause patients to have mucus, pus and bloody stools, and at the same time, the stool will change in shape, appear uneven, and there will be symptoms such as emaciation, fatigue, and anemia.

Colorectal cancer generally refers to colorectal cancer, which can cause symptoms such as abdominal pain, abdominal lumps, changes in bowel habits, and changes in stool properties. If you have bowel cancer, you should go to the hospital in time for surgery, radiotherapy, chemotherapy, etc.**.

Bowel cancer is a serious malignant tumor, and the main symptoms of bowel cancer patients are abdominal pain, bloating, constipation, diarrhea, and blood in the stool. Blood in the stool and constipation are the most typical symptoms of bowel cancer First of all, for some patients, if they eat high-fat foods for a long time, such as animal fats and animal offal, the risk of malignant tumors in the rectal and colon will increase significantly.

In fact, most patients with gastric cancer do not have obvious symptoms of discomfort in the early stage.

In recent years, gastric cancer has tended to be younger due to changes in dietary structure and increased work pressure.

Stomach cancer patients have symptoms of stomach pain in the early stages of the disease. At first, it is only a feeling of discomfort in the upper abdomen or a feeling of swelling and heaviness, and sometimes a dull pain in the heart sockets, so it is often mistaken for gastritis or ulcer disease, and the symptoms can be temporarily relieved. In some patients, loss of appetite, weight loss, and fatigue are also a common but non-specific early signs of gastric cancer.

If the lesion occurs in the patient's antrum, it can induce changes in the function of the duodenum, and rhythmic pain similar to ulcer disease appears, which is often ignored by the patient, until the patient's attention is not attracted until the patient's attention is caused by persistent pain or even symptoms such as melena or hematemesis, and at this time, the patient's condition has often developed to the advanced stage of gastric cancer, and the best opportunity has been lost.

The increasing incidence of colorectal cancer is mainly due to these factors.

1. Dietary factors:

Epidemiological studies have shown that dietary factors are an extremely important factor in the pathogenesis of tumors, because 70 90 percent of them are related to environmental factors and lifestyle, and 40 60 of them are related to diet and nutrition to a certain extent.

2. Occupational factors:

Although colorectal cancer is generally believed to be not an occupational disease, the relationship between occupational factors and the incidence of colorectal cancer still needs to be paid attention to. Workers producing asbestos insulation are more common in colorectal cancer patients, and animal experiments have also confirmed that ingested asbestos fibers can penetrate the intestinal mucosa. In addition, the standardized mortality and mortality rates of colorectal cancer are also higher in industries such as the metal industry, the cotton yarn or textile industry, and the leather manufacturing industry.

3. Disease ** element.

Colorectal adenoma is a precancerous lesion, and most studies believe that more than 80% of colorectal cancers occur on the basis of pre-existing adenomas. Therefore, all adenomas found in the examination should be removed to prevent the occurrence of colorectal cancer in the future. However, more than 30% of patients with colorectal adenoma removal will develop new adenomas, so close follow-up is required.

Ulcerative colitis can also cause colorectal cancer, which is more common in Europe and the United States, but the incidence in China has also increased in the past 20 years. Studies have found that the incidence of colorectal cancer among them is twice that of the general population (relative risk). This relative risk is related to the location of the lesion.

4. Genetic factors.

Bowel cancer can be inherited. There is a certain proportion of heredity in the hair of bowel cancer, and there are some bowel cancers or other malignant tumors, which are clustered by region and family. Reminder: It is important to pay attention to the fact that those who have a family history of cancer or bowel cancer and are over 40 years old are generally recommended to have a check-up once a year.

Therefore, for stomach cancer, early prevention and detection is crucial!
