what does a hemorrhoids look like,Viewing colorectal cancer from the living habits of urban young people

    Colorectal cancer includes colon cancer and rectal cancer. The incidence of colorectal cancer is rectum, sigmoid colon, cecum, ascending colon, descending colon, and transverse colon. The incidence rate increases with age. Due to the extension of human life span, the incidence and mortality of colorectal cancer are gradually increasing in China and the world, and it is one of the ten most common malignant tumors. There are 1.02 million new cases and 530,000 deaths worldwide each year. The latest statistics: The incidence of colorectal cancer in China has been "rising" year after year. The number of new cases is about 130,000 to 160,000 and the death toll is about 60,000 to 90,000. It mostly occurs in large and medium-sized cities and is second only to gastric cancer in gastrointestinal tumors. Ranked second. What is disturbing is that statistics from various countries show that the incidence of colorectal cancer, especially colon cancer, is rising rapidly, and young patients have always accounted for a certain proportion. Especially in large and medium cities, the age of onset is mostly around 45 years old.

    The incidence of colorectal cancer is showing an "urbanization" trend, with an incidence rate of 20/100,000, and an annual increase of 2%. This typical urban disease is seriously threatening the health of residents in large and medium cities. The more affluent areas, the higher the incidence. The diets of patients with colorectal cancer generally have the characteristics of "three highs and one low", that is, high fat, high protein, high calorie and low fiber. These excess nutrients are difficult to digest and stimulate the intestinal wall to cause defecation disorders, constipation, and accumulation of stool in the intestines. , Among them, the long-term retention of harmful substances brings the risk of colorectal cancer. In addition, due to the accelerated pace of life, there is no time to exercise and defecate, which is also the main cause of colorectal cancer in some young people.

    The occurrence and fatigue of colorectal cancer are directly related to prolonged dry stool and constipation. But it is also related to internal factors such as bad mood, mental factors, and gastrointestinal dysfunction. Due to the accelerated pace of life, there is no time to exercise and defecate, which is the main cause of colorectal cancer in some young people.

    There are four major characteristics that affect the prognosis of colorectal cancer in young people: First, there are few early detections. Digital rectal examination is not included in the routine physical examination options. Young people lack vigilance about the disease, and young women are even more ashamed of the examination. 60% of the diagnosed patients are in the middle and late stages. The second is the high degree of malignancy. Among young people diagnosed with colorectal cancer, more than 60% have metastasized. Third, there are many missed diagnoses. Clinical statistics found that the average time for colorectal cancer patients under 35 years old from feeling unwell to seeing a doctor and finally being diagnosed is 5 to 15 months, and 70% of patients are misdiagnosed as hemorrhoids, enteritis, and intestinal worms. Fourth, the treatment effect is poor. Because most patients are in the middle and advanced stages when they are diagnosed, the tumor has metastasized or invaded surrounding tissues and organs, and the 5-year survival rate after surgery is less than 30%. In view of the above characteristics, experts remind citizens that they should develop the habit of regular physical examinations from a young age, in addition to changing bad eating habits and eating more whole grains; it is also very important to develop the habit of regular bowel movements.

    Our living standards are getting better and better, and the food we eat is getting more refined. In fact, in the process of finishing, we lost a lot of useful things, of which cellulose is now considered the most important. Once the cellulose is eaten very little, the time it takes for feces to pass through the intestine is shortened, resulting in a reduction in volume and increasing the stimulation of carcinogens to the intestine, which is very unfavorable. Stool stays in the body for a long time, which can cause colorectal cancer. Due to bile acid in the stool, carcinogens are produced. The longer this carcinogen is in contact with the intestine in the stool, the greater the damage to the intestine.

    Many people love to eat deep-fried things and they are very fragrant. But it is actually a very bad eating habit. There are several main aspects. Firstly, once the high temperature of the oil is above 160 degrees, in fact, when you are cooking, when the oil smokes, it will be above 160 degrees. At this time, the oil itself It will decompose and decompose some carcinogens. There is also something to do with the food you make. If you fry fish or meat, protein will be denatured and carcinogens will also be decomposed. Grilling is even more troublesome. Many people in Beijing love to eat lamb kebabs. The phenyl-to-propylene ratio contained in a lamb kebab is a strong carcinogen, equivalent to 500 cigarettes. But don't be too scared, because the process of tumor occurrence is a very long and gradual process, that is to say, eat less, not at all. There are also some pickled foods. Frequent consumption of smoked foods can also induce colorectal cancer.

    Distinguish between colorectal cancer and hemorrhoids: The early symptoms of colorectal cancer have many similarities with hemorrhoids, so it is important to distinguish colorectal cancer and hemorrhoids early. The common point of colorectal cancer and hemorrhoids is blood in the stool, but there are three main differences: one is the increase or irregularity of the stool frequency of patients with colorectal cancer, while the hemorrhoid patients generally do not increase the frequency of stool; the second is bleeding and bleeding The condition is different. Colorectal cancer bleeding, blood and stool are often mixed together, causing more bleeding, while hemorrhoids bleeding usually occurs before or after stool, and the amount of bleeding is small; third, colorectal cancer develops to a certain degree, usually abdominal pain, but hemorrhoids will not stomach ache. The human large intestine is generally 1.5 meters long, and its symptoms vary depending on the location of the disease. When the course of the disease progresses to the middle and late stages, there will be abdominal pain. Rectal cancer will have a significant anal drop.

    If you find early symptoms, such as blood in the stool, increased stool frequency, abnormal stool shape, abdominal pain, etc., you must go to the hospital for examination in time to make early diagnosis and treatment. This is the key to ensuring effective treatment of colorectal cancer.
