Let’s take a look at the symptoms of colorectal cancer, the cause of colorectal cancer, and the foods that are good for colorectal cancer. Colorectal cancer is a malignant tumor that occurs in colons or rectum, and is an important disease that ranks second in the incidence among Koreans. In the early stages, it is often difficult to find because of the lack of symptoms or insignificant, but it is also a cancer with a high cure rate when it is found early. It is possible to prevent colon cancer by improving eating habits and lifestyle, and it is important to find early through regular checkups.
Colorectal cancer symptoms
Colorectal cancer is a malignant tumor that occurs in colon or rectum, and in the early days, it is often difficult to find because of the lack of symptoms or insignificant. Colorectal cancer has a high cure rate when found early, but regular checkups are important when symptoms appear. Symptoms of colon cancer may vary depending on the position and progress of the tumor, and the pattern of symptoms varies depending on the right colon cancer, the left colon cancer, and rectal cancer. It is important to recognize the symptoms of colorectal cancer early and consult with a medical professional.
Change of bowel habits
- Constipation and diarrhea: Changes in bowel habits are constantly appearing. Constipation and diarrhea may appear alternately, or you may see stools often or rarely than usual. In particular, if these changes persist for more than three weeks, you should consult with your doctor.
- Residue: It is the main symptom of rectal cancer that lasts the feeling that the stools remain after defecation. This occurs because the tumor takes up the space in the rectum and interferes with complete bowel movements. If these symptoms appear repeatedly, it is better to consult with a specialist.
Bloody and bleeding
- Bloody: Mixed with red or dark red blood in the stool is a typical symptom of colon cancer. Especially in the case of rectal cancer, the red bloody stool may appear, and the black blood stool may appear in the case of the right colon cancer. Bloody stools can also appear in benign diseases such as hemorrhoids, so accurate diagnosis is required.
- Anal bleeding: In some cases, there may be direct bleeding in the anus. If you have a lot of bleeding or persistent, you may cause anemia, so be careful. In particular, if there is an unknown bleeding at age 40 or older, you must be tested.
Abdominal symptoms
- Abdominal pain and bloating: When colon cancer progresses, pain in the abdomen may cause pain or bloating. Especially in the left colon cancer, the intestines can be narrowed and abdominal pain can be severe. Continuous abdominal discomfort is an important warning signal of colorectal cancer.
- Abdominal mass: In the case of colon cancer, the chunks can be touched in the abdomen. In particular, if the right column is in progress, the masses may be touched on the lower belly. If the chunks that were not before in the abdomen are touched, you should immediately consult your doctor.
Systemic symptoms
- Reduction of weight and poor appetite: Losing weight and loss of appetite are common symptoms of many cancers, including colon cancer. It is especially common in patients with colon cancer on the right. If you have unintended weight loss, it is a good idea to consult a medical professional.
- Anemia and fatigueChronic bleeding caused by colorectal cancer can cause anemia, which can cause symptoms such as fatigue, dizziness, and breathing. Especially in patients with colon cancer on the right, anemia symptoms are common. If there is an unknown anemia, it is necessary to consider colonic examination.
The symptoms of colorectal cancer may be insignificant or initially insignificant, so if you are over 50 years old or have a family history, it is important to have regular colon checks. If the symptoms mentioned above lasts for more than 2-3 weeks, you must consult a medical professional to get an appropriate test. Early detection can greatly increase the success rate of colon cancer treatment.
Causes of colorectal cancer
Colorectal cancer is a malignant tumor that occurs in colon or rectum, and has recently increased the incidence with westernization of diet. The occurrence of colon cancer is known to include environmental factors such as dietary habits, genetic factors, and inflammatory bowel diseases that cause chronic inflammation in the colon. Colorectal cancer tends to occur in proportion to age, which is common in age over 50 years of age. Accurately understanding the cause of colorectal cancer can help prevent and early detection.
Dietary factor
- Animal fat and red meat: Excessive intake of red meats such as animal fat and saturated fat, especially pork and beef, increases the risk of colon cancer. It is reported that the risk of colon cancer is further increased if you bake, fry, or barbecue. Eating a lot of animal fat through carnivores increases the production and secretion of cholesterol and bile acids in the liver, which increases the amount of bile acids in the large intestine.
- Low fibrillation: Lack of fiber intake increases the risk of colon cancer. The fiber reduces the intestinal passage time of the feces, reducing the time for the carcinogens and the intestinal mucosa. Processed refined low residual and alcohol intake also increases the risk of colorectal cancer.
Genetic factor
- Family5%of colon cancer is clearly caused by genetic, and about 15-20%of all colon cancer is related to genetic predisposition. Familiar adenomatous polyposis develops thousands of adenoma on the colon wall and develops almost 100% cancer when adults become adults.
- Genetic expenses species of colorectal cancer: Hereditary Non-Polyposis Colorectal Cancer is more common than family polyps. If these two diseases are known to increase the risk of developing colorectal cancer in immediate families by two to three times.
Line
- PolypsPolyp refers to a lesion formed like a hump, with part of the intestinal mucosa that protrudes from the surrounding mucosal surface. The greater the size of adenoma polyps (more than 1.0 cm in the surface diameter), the higher the hyper -level hydration, and the higher the characteristics such as Villous, the higher the carcinogenicity.
- Progress: The adenoma polyps found in the large intestine can be slowly performed in cancer over five to ten years. This is considered a precancard lesion in the occurrence of colon cancer, and early detection and removal are important.
Inflammatory bowel
- Increased riskInflammatory bowel disease can be classified as ulcerative colitis and crohn’s disease. The colon cancer is known to develop 20 to 30 years earlier than ordinary colon cancer.
- The effect of chronic inflammationIf chronic inflammation persists in the intestine, DNA damage and variation of intestinal mucosal cells accumulate, increasing the risk of cancer. Patients with inflammatory bowel disease are essential for regular colon checkups.
Since the causes of colorectal cancer are diverse and complex, dietary control, regular exercise, and regular checkups are important for prevention. Especially if you are over 50 years old or family history, it is important to find early through regular colonoscopy. Colorectal cancer is a cancer with a high cure rate, so it is necessary to recognize risk factors and take appropriate preventive measures.
Food for colorectal cancer
Colorectal cancer is a malignant tumor that occurs in colon or work, and is the main cancer that ranks second in Korea. Colorectal cancer is closely related to eating habits, which plays an important role in preventing proper diet. In particular, westernized eating habits are pointed out as a major cause of increased incidence of colon cancer, so the right food selection is essential. Eating foods that help prevent colorectal cancer can significantly lower the risk of cancer.
Vegetables and fruits
- Vegetables and fruits of various colors: It is recommended to eat more than 200g of vegetables and fruits per day. This corresponds to two baseball -sized fruits, two vegetables, and a plate of herbs. Vegetables and fruits are rich in fiber, vitamins, and antioxidant nutrients.
- 5 -color food: You need to eat red, yellow, green, purple and white foods to prevent colon cancer. Lycopene in red foods such as apples and tomatoes strengthens the intestinal mucosa. Beta -carotene of yellow foods such as pumpkin and carrots reduces cell damage and inflammatory reactions to enhance immunity. Green foods such as spinach and broccoli are rich in folic acid and vitamin C, which reduces the risk of colon cancer and colon polyps.
Beans and nuts
- Soybean: Eating beans with beans is effective in preventing colon cancer. Isoflavones rich in soybeans have the effect of preventing cancer cell proliferation. According to the National Cancer Center study, men who consumed more than 105g of beans such as tofu and bean sprouts per day were 33% lower than men who consumed less than 40g.
- nutsNuts rich in healthy fatty acids, fiber and flavonoids reduce the risk of colon cancer. Nuts such as almonds, cashew nuts, hazelnuts, pecans, pistachios, and macadamia also reduce the risk of type 2 diabetes, and diabetes is one of the risks of colon cancer. Especially in patients with 3rd cancer patients, nuts rich in nuts are related to cancer recurrence and reduction in mortality.
All grains and fiber
- Unrefined grain: All grains such as barley, brown rice, and quinoa are rich in essential fiber. High fiber meals help the intestinal bacteria fermentation, and can produce anticancer components such as bootyrates, a single -chain fatty acid. In addition, by increasing the volume of the stools, it prevents constipation and reduces the time of the intestinal residence of the stools to minimize the colon mucosa contact of carcinogenic substances.
- oatmealOatmeal is rich in dietary fiber, which helps to promote intestinal health. Dietary fibers promote the growth of the intestinal beneficial bacteria and reduce the time for carcinogens to contact the intestinal mucosa. According to a study of French Dijonburgundy University Hospital, people who have consistently consumed foods with many dietary fiber have lowered the risk of colon cancer by up to 52%.
Dairy and fish
- Low fat dairy: Calcium rich in dairy products such as low-fat milk, yogurt, cottage cheese, etc., combined with fatty acids and bile acids to form an insoluble calcium-soap to promote excretion of fat, reducing colon cancer. Insurance with vitamin D increases the absorption of calcium, which is effective in suppressing carcinogenesis.
- Fresh fishBishes such as herring, mackerel, salmon, sardines, tuna are rich in omega-3 fatty acids to help reduce inflammation in the body. Chronic inflammation causes continuous cell conversion and is related to several types of cancers, including colon cancer, so it is important to reduce this.
In order to prevent colon cancer, regular exercise, smoking cessation, and sobriety must be performed in addition to diet. In particular, it is important to maintain normal weight through proper exercise, to actively exercise intestinal exercise to maintain intestinal health. In addition, food is recommended to be cooked raw, boiled, or cooked, and baked or fried recipes can produce carcinogens.
FAQ
Q: What is the main symptom of colon cancer?
A: The main symptoms of colorectal cancer include changes in bowel habits (repeated constipation and diarrhea), bloody stools, abdominal pain and abdominal bloating, unknown weight loss and anorexia. In particular, rectal cancers are characterized by residuals and red blood stools after bowel movements, and the right colon cancer is the main symptom of anemia and fatigue. If these symptoms persist for more than 2-3 weeks, it is better to consult a medical professional.
Q: What is the main cause of colon cancer?
A: The main causes of colorectal cancer include dietary factors (excessive intake of animal fat and red meat, low fiber oil diet), genetic factors (family polyps, genetic expensive colon cancer), adenoma polyps, and inflammatory bowel disease. In particular, the incidence of colon cancer is increasing with westernized eating habits, and the risk of occurrence is increased in age over 50 years old. Regular checkups are essential if you have a family history or have inflammatory bowel disease.
Q: What food is good for preventing colon cancer?
A: Foods for preventing colon cancer include vegetables and fruits, soybeans and nuts, rich in all grains and fiber, low-fat dairy, and omega-3 fish. In particular, foods rich in dietary fiber reduce the time of stay in the intestines to minimize the contact of carcinogens, while foods rich in antioxidants prevent cell damage. On the other hand, red meat and meat, high -fat foods, and alcohol are recommended.
Q: When should I get colorectal cancer screening?
A: Colorectal cancer screening is generally recommended to start at age 50, and you should start earlier if you have a family history or risk factors such as inflammatory bowel disease. The national cancer screening project provides adults aged 50 or older every year, and recommend colonoscopy if there is any abnormalities. Color’s endoscopy is the most effective test for early detection of colon cancer. If you find polyps, you can immediately remove it to prevent the progression of cancer.
