What are the symptoms of small bowel cancer and what are the early signs of small bowel cancer?

The clinical manifestations of small bowel tumors are very atypical, often presenting with one or more of the following symptoms: 1

Abdominal pain is the most common symptom and is usually due to the stretching of the tumor. Intestinal peristalsis disorders can be caused by dull pain, swelling and even severe cramping, and the pain is particularly severe when complicated by intestinal obstruction. It can also be accompanied by diarrhea, loss of appetite, etc.

2.Intestinal bleeding is often intermittently tarry or bloody stools, or even heavy bleeding, and some are manifested as chronic anemia due to long-term repeated small bleeding that is not detected.

3.The most common cause of acute intestinal obstruction is intussusception, but the majority are chronic. Tumor-induced narrowing of the intestinal lumen and compression of the adjacent bowel are also causes of intestinal obstruction and can also induce volvulus.

4.Intra-abdominal masses are generally more mobile and more irregular in location.

5.Intestinal perforation is more common in small bowel malignancy, with acute perforation leading to peritonitis and chronic perforation leading to intestinal fistula.

6.Carcinoid syndrome is caused by bradykinin, an activator of serotonin and vasorelaxin, produced by carcinoid cells, and is characterized by paroxysmal flushing (telangiectasia) of the face, neck, and upper body, diarrhea, asthma, and valvular heart disease due to fibrous tissue hyperplasia. It is often triggered by eating, drinking, agitation, and compression of the tumor.

It is mostly seen in patients with carcinoid liver metastases.

Small bowel tumors are relatively rare tumors, and gastrointestinal tumors are most commonly gastric, colon and rectal tumors. The more common tumors of the small intestine are small bowel cancer, small intestinal lymphoma, and neuroendocrine tumor of the small intestine, and the main symptoms are as follows:

1. It often causes abdominal pain, because the tumor pulls in the intestine or causes spasm of the small intestine, causing the above symptoms, so abdominal pain is the most common clinical manifestation;

2. It may cause intestinal bleeding, and gastrointestinal bleeding is another clinical manifestation of the disease;

3. Intestinal obstruction, small intestine tumors often cause incomplete obstruction, so intestinal obstruction is also one of the clinical manifestations of small intestine tumors;

4. There are also some small intestine tumors that can cause intussusception, and emergency surgery is required if intussusception occurs;

5. Different intestinal tumors have different accompanying symptoms, such as neuroendocrine tumors may cause diarrhea, facial flushing and other clinical manifestations.

Although small bowel tumors are relatively rare, the symptoms of small bowel tumors are relatively insidious and the degree of malignancy is relatively high.

Hello: There are about 30 kinds of small intestine tumors, which are divided into two categories: benign and malignant, which are more common in middle-aged and elderly people over 50 years old, and the incidence rate is slightly higher in men than in women. Compared with the well-known "colon cancer" and "rectal cancer", there are many fewer tumors in the small intestine.

There are about 30 kinds of small intestine tumors, which are divided into two categories: benign and malignant, which are more common in middle-aged and elderly people over 50 years old, and the incidence rate is slightly higher in men than in women.

Although the small intestine is long, it is one of the organs in the body that is less prone to tumors because there are three physiological factors in the lumen of the small intestine that are different from the colon

1.Food is fluidized when digested by the stomach and enters the small intestine, which reduces the concentration of carcinogens.

2.There are fewer bacteria in the small intestine and relatively few carcinogens produced by bacteria.

3.The small intestine contains substances such as protective enzymes and immunoglobulins, which can attenuate the carcinogens in the intestinal lumen.

Because small bowel tumors are rare, their research is also less and not fully understood. Some gastrointestinal adenomas are genetic. Patients with immunoglobulin deficiency or immunosuppression** have a higher incidence of small bowel tumors.

Malignant tumors of the small intestine have been reported in patients with AIDS.

At present, surgery is the most effective method for small bowel tumors, and the scope of surgery should be determined according to the location, nature and relationship between the tumor and the surrounding organs. The details are as follows:

1. Benign tumors of the small intestine: for small intestine hemangiomas, the purpose of surgery is to ** the comorbidities caused by the tumor, and the diseased intestinal segment can be resected; Most small bowel lipomas do not interfere with normal life and can be removed without surgery;

2. Small intestinal stromal tumors and small intestine cancer need to be resected from the diseased intestinal segment, and a follow-up plan will be formulated according to the pathological results after surgery.

Your problem is like saying that someone has a stomachache but don't know what caused it.

What are the early symptoms of small bowel cancer? Having cancer brings great pain and financial pressure to patients and families. If it can be detected early and seek medical attention in time, the rate is relatively high. I will tell you about the early symptoms of small bowel cancer.

In the early stage of small bowel cancer, symptoms such as abdominal distention, discomfort, and indigestion may occur, and then changes in bowel habits, such as increased bowel movements, diarrhea or constipation, and abdominal pain before defecation. Later, there may be mucus or mucopurulent bloody stools.

Intestinal cancer can cause symptoms of poisoning in the early stages. Due to tumor ulceration and blood loss and toxin absorption, patients often have anemia, low-grade fever, fatigue, emaciation, edema and other early symptoms of small bowel cancer, especially anemia and emaciation.

Intestinal obstruction is manifested as symptoms of incomplete or complete low intestinal obstruction, such as abdominal distention, abdominal pain, constipation, or stool closure, which are early symptoms of small bowel cancer. Physical examination reveals abdominal distortion, bowel, local tenderness, and strong bowel sounds.

Exercise is of great benefit to patients with small bowel cancer. However, not all patients with small bowel cancer who participate in exercise have significant results, which is related to the mastery of the amount of exercise and whether the exercise program is appropriate. Patients with small bowel cancer generally choose walking, running, qigong, tai chi, etc. when exercising, but it should be noted that if the amount of exercise is too large or too small, it will not only fail to achieve satisfactory results, but may also be counterproductive.

Physical exercise for patients with small bowel cancer must be carried out in strict accordance with the principle of "aerobic metabolism", that is, the exercise must master the "heat", that is, all parts of the body can be fully active, but at the same time, the body must not have oxygen debt. The so-called "oxygen debt situation" means that when the amount of exercise or exercise intensity reaches a certain level, the oxygen inhaled by the respiratory organs cannot meet the needs of the body during exercise, and there is obvious breathlessness of breath.

Patients with small bowel cancer should pay attention to the number of heartbeats during exercise should not exceed the range of 95-120 times per minute, the breathing is deepened and lengthened, although the breathing rhythm increases, but there is no rhythm disorder, exercise to feel the most comfortable, or the body is slightly tired, but the spirit is still very comfortable can be ended, the amount of exercise should be gradual, do what you can, too small can not achieve the purpose of exercise, overwork is not only useless, but also harmful.

1. Reduce animal fat intake to prevent small intestine cancer.

Women who consume high fat have a 32% increased risk of small bowel cancer compared to women with low fat consumption, and reducing the amount of animal fat in food can help reduce the incidence of small bowel cancer.

2. Appropriately reduce energy intake to prevent small bowel cancer.

Most studies have shown that the total amount of energy consumed is related to the risk of developing small bowel cancer, and reducing total energy intake may reduce the incidence of small bowel cancer.

3. Dietary fiber prevents small bowel cancer.

Common small bowel diseases include: short bowel syndrome, inflammation of the small intestine, ulcers, tumors, small bowel diverticulum, vascular development and variation of the small intestine, small intestine dysfunction, hemangioma, etc. These diseases can lead to impaired absorption and digestion, causing problems such as hypoproteinemia and malnutrition.

There are many small intestine diseases, and you can go to the Department of Gastroenterology for enteroscopy to clarify the symptoms. Pay attention to your diet before you know what you are doing. 1. Pay attention not to eat cold, spicy, greasy, puffed fried, barbecue and other foods.

2. Eat smaller, more frequent meals, eat more easy-to-digest food, and eat lightly. 3. Eat more fresh vegetables and fruits, as well as a protein-rich diet. Occasionally, if you have discomfort in the small intestine, you can apply a hot towel to the abdomen, and if there is no relief, go to the hospital immediately for examination and find out**symptom**.

Inflammation of the small intestine Tumors of the short intestine.

Hello, the main symptoms of malignant intestinal tumors are:

1. Epigastric pain: intermittent vague pain at the beginning, and then gradually worsens and lasts. Pain is tolerable but should not be relieved or reappears after a short period of relief. 

2. Symptoms of epigastric fullness and discomfort, belching, acid reflux and dyspepsia: these manifestations are similar to chronic gastritis, peptic ulcer and other symptoms that are easy to be ignored by patients. 

3. Positive for hematemesis, black stool or fecal occult blood: it is often easy to mistake it for ulcer bleeding, especially when the amount of bleeding is small, it is only positive for fecal occult blood. 

4. Systemic symptoms such as emaciation and fatigue: a small number of patients often feel fatigue and weight loss. Therefore, for those with the above symptoms, they should be alert to the possibility of gastric cancer, and gastroscopy or X-ray examination can be done to confirm the diagnosis. 

If there is a tumor in the patient's intestine, the most common symptoms are lack of qi and blood, weight loss, more and more deformed stools, and blood in the stool, and some patients will also have a mass in the abdomen and intestinal obstruction. Generally, the location of the disease is more in the rectum, followed by the sigmoid colon, and there are fewer other parts. The early symptoms of intestinal tumors are related to the location of tumor growth, and the time of onset.

Tumors may appear in the large intestine, small intestine, and rectum, depending on the location, causing different symptoms. Some patients have mild or no symptoms in the early stages.
