Bowel cancer belongs to one of the common malignant tumors of the digestive tract, which has an extremely high incidence rate and the incidence rate is also showing a trend of rejuvenation. The incidence of bowel cancer is related to many factors, such as heredity, intestinal inflammation or dietary habits. Only early detection and timely diagnosis can improve the cure rate of bowel cancer, what are the early symptoms of bowel cancer?

One, change of bowel habit

Due to the stimulation of tumor growth, patients may have more frequent bowel movements or alternating constipation and diarrhea in a short period of time without any obvious cause, and this kind of diarrhea is usually with mucus. In addition, there will also be a feeling of incomplete bowel movement, the emergence of the urgent and heavy.

Two, abdominal pain or abdominal discomfort

When there is erosion or secondary infection of intestinal cancer, it will increase peristalsis and spasm of corresponding intestinal segments, thus causing abdominal pain. A part of the patients will have persistent hidden pain, some of them will just have abdominal distension or abdominal discomfort, and some of them will have intestinal obstructive abdominal pain, presenting paroxysmal colic that lasts only for a few minutes, and feeling that there is a gas passing through it, followed by farting, and finally the pain disappears.

Third, intestinal obstruction symptoms

With the enlargement of cancer cells, the intestinal lumen can become narrower and narrower, which may completely block the lumen, and food and feces can not pass through the intestines normally, thus causing cancerous intestinal obstruction.

Fourth, blood in stool

Blood in stool is the first symptom of bowel cancer, because it is easy to bleed after the friction between stool and cancer cells, and it is only occasional small amount of bleeding in mild cases, but in severe cases, it can be fresh blood, mucus blood or mucus pus and blood in stool. Many people will be confused with bleeding hemorrhoids, hemorrhoid bleeding symptoms are dripping blood or blood on the handkerchief, and may also show jet-like bleeding. If you can not better distinguish should go to the hospital to do anoscopy or anal fingerprinting, to rule out the possibility of bowel cancer.

Fifth, diarrhea

Continuous change of bowel habit, including sudden constipation, diarrhea or alternating between the two, as well as obvious increase in the frequency of bowel movement are some of the symptoms of rectal cancer.

Sixth, anemia

Blood in stool for a long time in patients with intestinal cancer may appear secondary anemia. As the cancer cells grow or infiltrate the muscle layer of intestinal wall, the intestinal tube will be narrowed, the intestinal lumen will become smaller, and the passage of intestinal contents will be hindered. In addition, as the cancer spreads, the surface of the cancer ulcerates, blood loss and toxin absorption, thus causing anemia, body wasting and weakness.

Dr. Zhao Tianyong warned: do not want to get bowel cancer, these 3 things, even if it is difficult to insist!

One: even if you are busy, you have to exercise

Exercise can increase the secretion of digestive juices, promote digestion, and can stimulate peristalsis of the colon, reduce the fecal matter in the intestinal tract storage time, and promote defecation, so that some carcinogens in the fat decomposition products have less chance to come into contact with the mucosa of the colon, and as a result, it will make the risk of colon cancer decrease.

Two: stay away from smoked and fried food

Eating more oil, meat, and coarse grains, vegetables, plus too little exercise will lead to slow down the speed of gastrointestinal peristalsis, which is easy to cause constipation.

At the same time, eating more high-fat food will also increase the secretion of bile acids in the intestinal tract, forming an irritation and damage to the intestinal mucosa. Over time, this will increase the risk of bowel cancer.

Consuming too much smoked and baked food can increase carcinogens such as nitrosamines in the body.

Three: Regular work and rest

Stress and irregular work and rest are two easy-to-ignore triggers of rectal cancer. When people are fatigued and work under too much pressure, it will lead to the decline of intestinal resistance and immunity, giving cancer a chance to take advantage of.

Tips

As long as there are these symptoms, you need to go to the hospital in time to do fecal occult blood test, which can detect and diagnose colorectal cancer at an early stage. People with too little physical activity are prone to colorectal cancer, so it is important to participate in more outdoor activities to promote gastrointestinal motility. The diet should include more green leafy vegetables and fruits as well as foods containing dietary fiber, increase the proportion of coarse grains and miscellaneous grains, and eat less high-fat foods, especially to control the intake of animal fats. people over 40 years of age, patients with familial polyps, and those with a family history of colorectal cancer need to be examined on a regular basis.
