What does small bowel cancer inchoate symptom have?

summary

In my years of clinical diagnosis and treatment, I found that small intestinal cancer has no obvious specificity, and there is no discomfort in the early stage. Many research data at home and abroad show that the main symptoms of advanced stage are abdominal pain (15% ~ 68%), nausea / vomiting (10% ~ 39%), intestinal obstruction or pyloric obstruction (10% ~ 42%), weight loss (10% ~ 42%), anemia (18% ~ 24%), abdominal mass (8% ~ 21%), gastrointestinal bleeding, fatigue, diarrhea / constipation, etc. What does small bowel cancer inchoate symptom have? Let's talk about it.

What does small bowel cancer inchoate symptom have?

1. Abdominal pain is the most common symptom. It can be caused by ulceration on the surface of tumor, intestinal spasm caused by stimulation of intestinal tube, intestinal obstruction or intussusception. When the tumor is huge and protrudes into the intestinal cavity, it can cause intestinal obstruction; Tumor invasion of the intestinal wall can cause intestinal stenosis and obstruction. This kind of obstruction is mainly due to small intestinal malignant tumor. Intussusception is mostly caused by benign tumor of small intestine. Can be acute attack, can also be repeated chronic attack.

2. About 1 / 3 ~ 2 / 3 patients with gastrointestinal bleeding are caused by tumor surface ulceration. Most of them are negative bleeding, manifested as fecal occult blood test positive or black stool, iron deficiency anemia can also be produced for a long time. There may also be intermittent small amount of bleeding, or even a large number of hematochezia.

3. Due to the large activity and unfixed position of the small intestine, the abdominal mass can occasionally buckle to the mass in the experience of small intestine tumor, but sometimes it can't be touched, sometimes it can't be found. Most of the palpable masses are large tumors.

matters needing attention

1, reduce energy intake: most studies have shown that the total intake of energy (protein, fat or carbohydrate) is associated with the risk of small bowel cancer. Reducing total energy intake may reduce the incidence rate of small bowel cancer. 2. Reduce animal fat intake: compared with low-fat women, high-fat women have a 32% increased risk of small bowel cancer. Reducing the amount of animal fat in food can help reduce the incidence of small bowel cancer. 3. Dietary fiber can adsorb carcinogens to promote defecation: dietary fiber in food can increase fecal amount, adsorb bile acid salt to dilute carcinogens in intestinal tract, so as to reduce the occurrence of small bowel cancer, so we should eat more vegetables and fruits rich in dietary fiber in daily life.
