For example, the most common abdominal pain and blood in the stool are common symptoms of colon cancer, but these symptoms are easy for us to ignore. In this case, let's take a comprehensive look at the symptoms of colon cancer and actively prevent colon cancer.

What are the common symptoms of colon cancer?

1. Blood in the stool and abdominal pain. The patient is diagnosed with abdominal pain and black or bloody stools. Indeed, colon cancer often results in bloody stools, or pus and blood in the stools. When blood is mixed with the feces, the stool becomes jam-like.

This is due to erosion and necrosis of the lower colon or rectal cancer, which causes bloody stools. Intestinal cancer often causes erosion, necrosis and secondary infection, which increases the peristalsis of the corresponding intestinal segments and causes intestinal flexure spasm, often causing abdominal pain of varying nature and degree.

2. Gastrointestinal symptoms. Symptoms include abdominal bloating and discomfort or indigestion-like symptoms. Among them, right colon cancer usually presents with abdominal pain, discomfort or dull pain. It may be intermittent at first and then become continuous.

3. Symptoms related to intestinal obstruction. Symptoms such as bloating, abdominal pain, constipation or constipation often occur. During physical examination, colon tumors can show abdominal distension, intestinal shape, local tenderness, and hyperactive bowel sounds.

4. Abdominal mass. The location of the mass depends on the location of the cancer. The mass of the cecum, ascending colon, and hepatic flexure of the colon is located in the lower right, middle right, and right upper abdomen respectively. The mass of the transverse colon cancer can be palpated around the umbilicus. The mass is firm and varies in size, with a nodular appearance on the surface. It can generally be pushed, but becomes fixed in the later stages. People with co-infections may experience tenderness.

5. Symptoms of poisoning. The early symptoms of colon cancer are due to tumor ulceration, blood loss and toxin absorption, which often cause patients to have anemia, low fever, fatigue, weight loss, edema and other symptoms, especially anemia and weight loss.

When colon cancer reaches an advanced stage, signs of liver metastasis such as jaundice, ascites, and edema may appear, as well as cachexia, rectal concave masses, supraclavicular lymph node enlargement, and other manifestations of distant tumor spread and metastasis.

So, how to prevent colon cancer?1. Develop good living habits, quit smoking and limit alcohol consumption. Smoking, the World Health Organization predicts that if people stop smoking, the number of cancers in the world will be reduced by 1/3 in 5 years; secondly, do not drink alcohol. Cigarettes and alcohol are extremely acidic substances. People who smoke and drink for a long time can easily develop an acidic constitution.

2. Pay attention to your diet. Avoid food that is too salty, too spicy, or too oily, and do not eat food that is too hot, too cold, or that has gone bad. Pay attention to a balanced nutritional mix. Eat more fruits, vegetables, staple foods, and high-fiber foods, and eat meat in moderation. , Eat less high-sugar, high-fat and other foods. Do not eat contaminated food, such as contaminated water, crops, poultry, fish eggs, moldy food, etc. Eat some green organic food to prevent diseases from entering the mouth.

3. Maintain a good attitude to cope with pressure, balance work and rest, and avoid excessive fatigue. It can be seen that stress is an important cause of cancer. Life must be regular. People with irregular living habits and people who often stay up late are more likely to get cancer. A good work and rest schedule should be developed to ensure adequate sleep.

4. Strengthen physical exercise, enhance physical fitness, and insist on moderate-intensity exercise for about 30 minutes every day, which will help increase metabolism and improve immunity. It is also recommended to exercise more in the sun.

5. Actively conduct physical examinations to control intestinal polyps, etc. Deng Haijun, deputy chief physician of the General Surgery Department of Nanfang Hospital of Southern Medical University, said in an online interview with Family Doctor that polyps are divided into inflammatory polyps and adenomatous polyps. Two-thirds of polyps are adenomatous polyps, and inflammatory polyps generally do not Cancerous, but adenomatous polyps have a higher chance of becoming cancerous. Therefore, if patients have adenomatous polyps, they need to remove the polyps under colonoscopy and undergo regular colonoscopy to monitor the recurrence of polyps.
