Colorectal cancer, including colon cancer and rectal cancer, is one of the more common malignant tumors of the gastrointestinal system and has a high mortality rate. According to the survey statistics, the incidence of colorectal cancer in the world is increasing at an average annual rate of 2%, and according to the survey in Shanghai, the incidence of colorectal cancer in China is increasing twice as fast as the world average, reaching 4% annual increase. So, how to recognize colorectal cancer?
Colorectal cancer is related to bad dietary habits
1.High-fat, high-protein, high-calorie, low-fiber diet and diet lacking certain trace elements will increase the chance of colorectal cancer
When the body consumes too much food with high fat and high protein, it needs to secrete more bile into the intestine to help digestion and absorption, and the bile will be decomposed into secondary bile acids by anaerobic bacteria in the intestine, which are highly toxic carcinogens and can cause intestinal mucosa carcinogenesis if they act on the intestinal mucosa for a long time. In addition, fiber is good for defecation, if the body consumes too little fiber in food, it will not be able to have the discharge of these waste residues in the intestine for a longer period of time, the greater the stimulation of toxins contained in the intestinal mucosa, resulting in an increased risk of cancer of intestinal mucosa cells.
2.Blood in stool
The early lesions of colorectal cancer are limited to the mucosa, patients may have no symptoms or only have changes in bowel habits, but when the tumor grows to a certain extent, blood in stool may appear, most patients with rectal cancer have fresh blood, and most patients with colon cancer have dark red blood;
3.Mucus stool and pus and blood stool
When the cancer ruptures, the patient’s stool often contains bright red or dark red blood and mucus, and the stool is mixed with blood;
4.Change of bowel habit
Patients with colon cancer may change the number of stools from once a day to two or three times a day, and the feeling of incomplete stools may appear after each stool;
5.There are often alternating cases of diarrhea and constipation
6.Symptoms of abdominal pain and bloating
Since the growth of cancer tumor may lead to intestinal obstruction, patients with colorectal cancer are prone to symptoms such as abdominal distension and abdominal pain, among which abdominal pain is more likely to occur, mostly in the middle and lower abdomen, with varying degrees of severity, mostly hidden pain or distension.
7.Symptoms such as anemia and emaciation
As the disease progresses, patients with colon cancer may have chronic wasting symptoms, such as anemia, thinness, fatigue and fever, and even cachexia, accompanied by fatigue and unexplained weight loss. This situation is related to patients’ blood in stool, insufficient nutrition and excessive consumption.
Effective prevention of colorectal cancer
The early symptoms of colorectal cancer are mild and not easy to be detected in time, so people should develop good habits to prevent the occurrence of the disease.
1.Adhere to physical exercise to improve body immunity, pay attention to relieve your stress and maintain a good state of mind.
2, to develop good eating habits do not prefer high amounts of high fat, high protein, low-fiber diet, eat less barbecue fried food, eat more coarse grains, vegetables, fruits and other foods containing more fiber.
3.Keep the stool smooth. Stool contains many carcinogenic substances, if these harmful substances stay in the intestine for a long time, it will play a role in the occurrence of colorectal cancer;
4, prevention of intestinal diseases, active treatment of precancerous lesions such as ulcerative colitis constipation schistosomiasis and intestinal canal, kind of ulcerative lesions, should be actively treated to prevent its cancer.
People with a history of familial colorectal cancer, patients with adenomatous polyps, patients with long-term chronic colitis, and people over 40 years old with unexplained stool abnormalities should undergo occult blood and exfoliative cell examinations in a timely manner.
Treatment of colorectal cancer
According to different parts of colorectal cancer, laparoscopic radical colorectal cancer surgery can achieve the same radical effect, and the patient’s bed is greatly reduced, which is more conducive to postoperative recovery.
