7 types of people are prone to colorectal cancer? What are the early symptoms of colorectal cancer?

7 groups of people are prone to colorectal cancer. What are the early symptoms of colorectal cancer? Sometimes, our body will have some symptoms when it is sick, but many times we will ignore them. The occurrence of colorectal cancer is also a more frequent cancer in recent years. So when colorectal cancer occurs, do you know what symptoms will appear when colorectal cancer occurs? Let's take a look at this together.

Early symptoms of colorectal cancer

1. Blood in stool: Blood in stool is more obvious when colorectal cancer occurs. The appearance of blood in stool is mainly characterized by intelligent light symptoms. In mild cases, it only manifests as occasional small amounts of bleeding. In severe cases, it manifests as mucus and blood in stool, mucus, pus and blood in stool, or fresh blood in stool. It is often misdiagnosed as dysentery or hemorrhoidal bleeding.

2. Lower abdominal pain: Abdominal pain can also occur in patients with colorectal cancer, although not all patients will experience it. Some patients have vague persistent dull pain as the first or prominent symptom, and some patients only feel abdominal discomfort or bloating. When combined with erosion, obstruction or secondary infection, obvious abdominal colic may occur due to increased peristalsis and spasm of the corresponding intestinal segment. Some patients present with typical abdominal pain of incomplete intestinal obstruction, that is, the pain is paroxysmal colic, lasting for several minutes, and they feel that there is gas running through the pain, followed by gas discharge, and then the pain suddenly disappears. When this symptom occurs in the elderly, colorectal cancer should be considered first.

3. Changes in bowel habits: Another obvious symptom of early colorectal cancer is a change in bowel movement frequency. For example, you may have bowel movements once a day, but now you have bowel movements 3-4 times a day for unknown reasons. Or, diarrhea and constipation may occur alternately. The shape of the stool may change. The stool may be soft but become thinner recently. Some patients may also feel a sense of urgency and heaviness.

4. Anemia: Elderly patients, especially those without other causes of blood loss and intestinal parasites, should be considered for the possibility of stomach or colorectal cancer if they are found to have progressive iron deficiency anemia.

Causes of Colorectal Cancer

1. Obesity: Obesity is an independent risk factor for colorectal cancer.

2. Smoking and drinking: Both smoking and drinking may increase the incidence of colorectal cancer.

3. Dietary factors: People who eat a lot of meat have a higher risk of colorectal cancer and rectal cancer, while vegetarians have a lower incidence rate; vegetables and fruits can reduce the incidence of colorectal cancer.

4. Lack of exercise: Physical exercise can reduce the incidence of disease, while lack of physical exercise in daily life increases the incidence of colorectal cancer.

5. Diabetes: Type 2 diabetes and colorectal cancer are more closely related. Not only do they share common risk factors, but diabetes itself is also a high-risk factor for colorectal cancer.

6. Adenomatous polyps: 80% of colorectal cancer originates from adenomatous polyps. Regular colonoscopy and treatment can prevent polyps from becoming malignant.

How to prevent colorectal cancer

Dietary adjustment

Although colorectal cancer has a certain genetic tendency, the vast majority of sporadic colorectal cancers are closely related to environmental factors, especially dietary factors. Dietary intervention can reduce the incidence of colorectal cancer.

Obesity and exercise

Obesity, especially abdominal obesity, is a risk factor for colorectal cancer. Lack of physical exercise is also a risk factor for colorectal cancer. Physical exercise can affect colon peristalsis and facilitate defecation, thereby preventing colorectal cancer. It is a way to prevent colorectal cancer.

Fruits, vegetables and dietary fiber.

Fiber can increase the excretion in the colon, dilute carcinogens, absorb bile salts, and reduce the incidence of colorectal cancer. Therefore, in your daily diet, you should eat more vegetables, fruits, and cellulose, eat a reasonable diet, and reduce the incidence of colorectal cancer.

Energy intake

Energy intake is related to the occurrence of colorectal cancer. Most studies have shown that total energy intake is related to the risk of colorectal cancer, regardless of whether the energy intake is protein, fat or carbohydrate. Reducing energy intake may reduce the incidence of colorectal cancer.

Vitamins and trace elements

Although the supplementation of vitamins A, C, and E can transform the hyperplasia of colon epithelium in patients with adenoma back to normal, the use of antioxidants to prevent colorectal cancer is not supported at present. The relationship between trace elements and colorectal cancer is not yet fully understood. Folic acid can reduce the occurrence of colorectal cancer, but the mechanism is still unclear.

7 types of people are prone to colorectal cancer

1. Like to eat high-fat, high-protein foods. Water is essential for the intestines. Therefore, many people suffer from intestinal diseases due to insufficient water and dietary fiber in their diet. The risk of colorectal cancer is significantly higher than that of the general population if they mainly consume high-fat and high-protein foods, such as animal protein, alcohol, fried foods, etc. Since these high-protein, low-fiber foods affect the normal peristalsis speed of the intestines, causing feces to stay in the intestines for a long time, it is easy to produce toxins. In the long run, the risk of cancer is also very high.

2. People over 40 years old. In fact, cancer can be induced at different ages, and the same is true for colorectal cancer. However, clinical cases show that more than 90% of patients are over 40 years old. This shows that regular rectal examinations are very necessary for people in this age group.

3. People with long-term constipation and blood in the stool. Data show that perhaps eight adults do not know that blood in the stool is a sign of colon cancer. Long-term constipation can cause dry stools, accumulation of toxins in the intestines, and recirculation, which can induce blood in the stool in severe cases. Experts say that blood in the stool can be used as a precancer warning.

4. People with chronic diseases. Although some chronic intestinal diseases may not develop into cancer, clinical studies have shown that patients with chronic ulcerative colitis for more than ten years have a several times higher risk of colorectal cancer than the general population; and patients with colorectal polyps have a 22 times higher risk than normal people. There are also intestinal diseases such as colorectal adenoma and familial adenomatous colon. In addition, non-intestinal diseases can also lead to the risk of colorectal cancer, such as schistosomiasis, long-standing chronic appendicitis, cholecystitis, or people who have had their appendix and gallbladder removed.

5. The patient has a family history of colorectal cancer. Nearly 1/4 of colorectal cancer patients may be related to genetic factors. For example, people with a family history of adenomatous polyposis, hereditary non-polyposis and other diseases have a 2-4 times higher risk of colorectal cancer than the general population.

6. Long-term depression. Work, study, and life may lead to mental stress in individuals. In severe cases, they may also experience depression, tension, anxiety, and other symptoms. This psychological discomfort can easily lead to physiological changes, such as abdominal pain, diarrhea, and frequent bowel movements. This is the so-called "irritable bowel syndrome." Abnormal intestinal peristalsis and abnormal detoxification function are more dangerous.

7. People who stay up late for a long time will have this situation. Staying up late for a long time can induce many diseases, cause toxins to accumulate in the intestines, slow down metabolism, and under long-term effects, there is a risk of cancer.

Summary: I believe that everyone has learned about the early symptoms of colorectal cancer through the above reading. In life, we will also share with you the causes that lead to the occurrence of colorectal cancer. I hope everyone will pay attention to avoid this situation in life.
