The incidence of rectal cancer is increasing year by year and our health is under serious threat. Rectal cancer is most common in people after 40 years old, and most of the main symptoms are blood in stool. There are many causes of blood in stool, generally speaking, they are divided into two categories: benign diseases (hemorrhoids, anal fissure, inflammatory bowel disease) and malignant tumors (rectal cancer, colon cancer, etc.), of which hemorrhoids are the most common benign diseases causing blood in stool, and rectal cancer is the most common malignant tumor. Eight types of people are more likely to suffer from rectal cancer 1, people with family history of rectal cancer, mainly refers to the immediate blood relatives in which someone suffers from rectal cancer. 2.People with history of malignant tumor, such as breast cancer. 3.Previously suffered from colorectal cancer. 4.Other colorectal diseases, such as rectal polyps and chronic rectal inflammation. 5, People over 40 years old in areas with high incidence of colorectal cancer (e.g. Guangzhou, where the incidence rate of colorectal cancer ranks first among 31 tumor registries in China). 6, People with high fat and high protein diet. 7.People who have received radiation therapy to the pelvis. In addition, smoking and obesity may have some relationship with rectal cancer. The above people should do fecal occult blood examination every year, and generally should do three times of fecal occult blood, and those who are positive should be further examined, i.e. colonoscopy, and rectal tissue biopsy should be taken if necessary. Rectal cancer favors “heavy taste”, these triggers should be avoided 1, high-fat, low-fiber dietary habits Undesirable dietary habits are important factors that induce rectal cancer, especially high-fat, low-fiber dietary habits. As high-fat food will increase methylcholanthrene in feces, leading to the increase of bile acid secretion, and insufficient dietary fiber intake leads to the increase of feces staying time in intestines, resulting in the increase of intestinal absorption of carcinogens, increasing the chances of cancerous changes, which raises the incidence risk of rectal cancer. In order to do a good job in preventing rectal cancer, it is necessary to reduce the intake of fat in daily life, and at the same time consume fresh vegetables and fruits many times, especially the food rich in dietary fiber. 2, Sedentary lifestyle Sedentary lifestyle is also one of the three major lifestyle habits that can easily induce rectal cancer, which requires special vigilance. On the one hand, being sedentary will lead to slower digestion, decomposition and excretion of ingested fats and proteins, due to which intestinal metabolites will stay in the intestines for a long period of time, thus increasing the time of stimulation of intestinal tract by harmful substances and increasing the risk of incidence of rectal cancer; on the other hand, being sedentary will lead to the slowing down of pelvic cavity and lumbar-sacral blood circulation due to pressure, which is easy to induce hemorrhoids and constipation, and will also reduce the immunity of the body, which will increase the risk of incidence of rectal cancer as well. At the same time, it will reduce the immunity of the body, which will also increase the risk of rectal cancer. In order to prevent the occurrence of rectal cancer, it is necessary to change the sedentary habit in daily life. With the accelerated pace of life and increased pressure of life and work, many people often have to hold their urine and stool for a long time before they can solve the problem. This kind of bad habit is an important factor that induces rectal cancer, and it needs to be especially vigilant. This kind of bad habit is an important factor to induce rectal cancer and requires special vigilance. Stool and urine contain many kinds of carcinogenic substances, and holding stool frequently will cause these carcinogenic substances to stay in the intestines for a long period of time and increase the absorption of these carcinogenic substances in the intestines, thus increasing the risk of developing rectal cancer. To prevent rectal cancer, you must change this habit in your daily life and solve the problem in time when you have the urge to urinate or defecate. Think about it, how many people are shot by the causes that induce rectal cancer? If, unfortunately, you have all these factors that trigger rectal cancer, how can you tell if you have rectal cancer? Hemorrhoids don’t turn into rectal cancer, but they can provide cover “Can hemorrhoids evolve into rectal cancer?” This question is of great concern to everyone. In fact, hemorrhoids and tumors are two diseases of different natures. Hemorrhoids are soft venous masses formed when the veins under the skin at the end of the rectum (that is, inside and outside the anus) undergo expansion and flexion. Tumor is a heterogeneous transformation of colorectal mucosal cells into cancerous cells. Current research has not found any precedent of hemorrhoids evolving into rectal cancer. However, some patients in the clinic said, “How did hemorrhoids become rectal cancer?” In fact, sometimes the symptoms of hemorrhoids cover up the symptoms of rectal cancer, delaying the early detection of rectal cancer, instead of hemorrhoids becoming rectal cancer. How to Identify Rectal Cancer and Hemorrhoids Early So how can you tell the difference between hemorrhoids and rectal cancer without delay? Everyone and look down. Difference between hemorrhoids and rectal cancer Hemorrhoids are usually bright red, blood floating on the surface of the stool, bleeding during defecation, which will stop by itself after defecation. Rectal cancer has darker blood, blood and stool are often mixed together, and in many cases, there is mucus or pus. Difference in Bowel Habits Rectal cancer will cause changes in bowel habits, such as thinner stools, more frequent bowel movements or constipation alternating with diarrhea. Hemorrhoids do not cause these changes. Rectal cancer is often accompanied by other symptoms 1.Pain in defecation: about 50% of rectal cancer patients have pain in defecation, the degree of which varies from mild to severe. Abdominal pain: some patients have hidden abdominal pain as prominent symptom, while some others have paroxysmal colic pain, accompanied by abdominal distension. 3.Weakness, anemia and abdominal mass: due to the consumption of the tumor, patients may also have systemic symptoms such as anemia, weakness, weight loss and low fever. In case of hemorrhoids, it rarely causes these discomforts. As soon as the above symptoms are noticed, the patient should go to the hospital for examination. Generally speaking, rectal fingerprinting can detect more than 75% of rectal cancers, and colonoscopy can detect almost all rectal cancers. Keeping your mouth shut can prevent 90% of rectal cancers Whether you are a high-risk group for rectal cancer or not, it is responsible for your health to follow these suggestions. 1. Eat less or no food rich in saturated fat and cholesterol: red meat (pork, beef, mutton), oil, animal offal, fried food, etc. 2, eat less or do not eat pickled food: our scholars also found that often eat pickled food, rectal cancer incidence increased, so we try to eat less or not eat. Limit oil: vegetable oil, including peanut oil, soybean oil, canola oil, etc., should be limited to about 20-30 grams per person per day, which is about 2-3 tablespoons. 4, eat more food rich in dietary fiber: eat more taro, soybeans and their products, fresh vegetables and fruits, algae and so on. Under the premise of maintaining the same amount of staple food, replace fine grains with some coarse grains. 5, supplement vitamins and trace elements: our scientists found that selenium, calcium, carotene, vitamin B2, vitamin C, vitamin E have the effect of reducing the occurrence of colorectal cancer. Therefore, moderate consumption of walnuts, peanuts, dairy products, lean meat, seafood, etc., supplement vitamin E; pay attention to the intake of malt, fish, mushrooms and other food rich in trace elements such as selenium; moderate consumption of food containing monounsaturated fatty acids, such as olive oil, tuna, etc.. 6. Adopt healthy living habits: On the basis of keeping our mouth shut, we should also quit smoking and limit alcohol, actively exercise, ensure sleep and develop good and healthy living habits. Compared with many hidden cancers (such as pancreatic cancer), rectal cancer is easier to be detected at an early stage. The treatment of early cancer can often achieve the effect of “cure”, and rectal cancer is no exception. The early deaths of many celebrities have once again sounded the alarm that “early detection, early diagnosis and early treatment” is definitely not just a slogan in the face of diseases!
