Rectal cancer that was misdiagnosed in those years
The incidence of rectal cancer is increasing year by year, and our health is seriously threatened. Rectal cancer is more common in people after the age of 40, and most of the main symptoms are blood in the stool. There are many reasons for blood in the 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.). Among them, hemorrhoids are the most common benign diseases that cause blood in the stool. Rectal cancer is the most common malignant tumor.
Eight types of people are more likely to develop rectal cancer
❶ People with a family history of rectal cancer mainly refer to someone who has rectal cancer in their direct blood relatives.
❷ People with a history of malignant tumors, such as breast cancer.
❸ Have had colorectal cancer before.
❹ Other colorectal diseases, such as rectal polyps, chronic rectal inflammation.
❺ Areas with a high incidence of colorectal cancer (such as Guangzhou, Guangzhou has the highest incidence of colorectal cancer among the 31 tumor registration sites in the country) people over 40 years old.
❻ People who eat high fat and high protein.
❼People who have received radiation therapy in their pelvis.
❽In addition, smoking and obesity may have some relationship with rectal cancer.
Doctor’s suggestion: The above population should be checked for fecal occult blood every year, usually three times for fecal occult blood. Those who are positive need further examination, namely colonoscopy, and rectal tissue biopsy if necessary.
Rectal cancer most favors "heavy taste", these triggers should be avoided
1. High-fat, low-fiber diet
Poor eating habits are an important factor in inducing rectal cancer, especially high-fat, low-fiber eating habits. Because high-fat foods increase the methylcholanthracene in feces, leading to increased bile acid secretion, and insufficient dietary fiber intake leads to an increase in the residence time of feces in the intestines, resulting in an increase in intestinal absorption of carcinogens, and increasing the risk of cancer. Increase the risk of rectal cancer. In order to prevent rectal cancer, it is necessary to reduce fat intake in daily life, and fresh vegetables and fruits, especially foods rich in dietary fiber.
Being sedentary is also one of the three major lifestyle habits that easily induce rectal cancer, and you need to be particularly vigilant. On the one hand, sitting for a long time will lead to slower digestion, decomposition and excretion of ingested fat and protein. Since intestinal metabolites stay in the intestine for a long time, it will increase the time for harmful substances to stimulate the intestine and increase the incidence of rectal cancer. Risk; on the other hand, sitting for a long time will cause the blood circulation of the pelvic cavity and lumbosacral region to be slowed down due to compression, which can easily induce diseases such as hemorrhoids and constipation. At the same time, it will reduce the body's immunity and also increase the risk of rectal cancer. . In order to prevent rectal cancer, the sedentary lifestyle must be changed in daily life.
3. Holding back urine
With the accelerating pace of life and the increasing pressure of life and work, many people often have to hold back for a long time when they feel urinary or defecation. This kind of bad lifestyle is an important factor in inducing rectal cancer and requires special attention. . Stool and urine contain a variety of carcinogens. Frequent holding back will cause these carcinogens to stay in the intestine for a long time, increase the absorption of these carcinogens in the intestine, and increase the risk of rectal cancer. To prevent rectal cancer, you must change this lifestyle in your daily life, and solve it in time when you feel urinary or defecation.
Think about it, how many people were shot at the cause of rectal cancer? If unfortunately, these factors that induce rectal cancer are all there, how do you judge whether you have rectal cancer?
Hemorrhoids will not turn into rectal cancer, but they can be covered
"Will hemorrhoids evolve into rectal cancer?" Everyone is very concerned about this question.
In fact, hemorrhoids and tumors are two different diseases. Hemorrhoids are soft veins formed by the expansion and flexion of the subcutaneous veins at the end of the rectum (that is, inside and outside the anus). The tumor is the metamorphosis of colorectal mucosal cells into cancer cells. The current research has not found a precedent for the evolution of hemorrhoids 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 and delay the early detection of rectal cancer, instead of hemorrhoids becoming rectal cancer.
How to recognize rectal cancer and hemorrhoids early
So how to distinguish between hemorrhoids and rectal cancer without delaying the condition? Let's look down.
Blood in the stool
Hemorrhoids have blood in the stool, which is usually bright red with blood floating on the surface of the stool. The bleeding will stop after defecation. The color of rectal cancer is dark, blood and stool are often mixed together, and in many cases mucus or pus is also mixed.
The difference in bowel habits
Rectal cancer will have changes in bowel habits, such as thinner stools, increased frequency or alternating constipation and diarrhea. Hemorrhoids will not cause these changes.
Rectal cancer is often accompanied by other symptoms
❶ Pain during defecation: About 50% of patients with rectal cancer have pain during defecation, ranging from mild to severe.
❷ Abdominal pain: Some patients have dull abdominal pain as a prominent symptom, and some patients have paroxysmal colic with abdominal distension.
❸Asthenia, anemia and abdominal masses: due to the consumption of tumors, patients may also have systemic symptoms such as anemia, weakness, weight loss, and low-grade fever. If it is hemorrhoids, these discomforts are rarely caused.
The doctor recommends: Once you find the above symptoms, you should go to the hospital for examination immediately. Generally speaking, digital rectal examination can find more than 75% of rectal cancer, and colonoscopy can find almost all rectal cancer.
Controlling your mouth can prevent 90% of rectal cancer
Whether you are a high-risk group of rectal cancer or not, you must follow these recommendations, which are responsible for your own health.
❶ Eat less or skip foods rich in saturated fat and cholesterol: red meat (pig, beef, lamb), oil, animal organs, fried foods, etc.
❷ Eat less or skip pickled foods: Chinese scholars have also found that people who eat pickled foods often have an increased chance of developing rectal cancer, so we try to eat less or not.
❸ Oil limit: Vegetable oils, including peanut oil, soybean oil, rapeseed oil, etc., are limited to about 20-30 grams per person per day, which is about 2 to 3 tablespoons.
❹ Eat more foods rich in dietary fiber: Eat more taro, soybeans and their products, fresh vegetables and fruits, algae, etc. Under the premise of maintaining the same amount of staple food, use part of coarse grains to replace fine grains.
❺ Supplement of vitamins and trace elements: Chinese scientists have found that selenium, calcium, carotene, vitamin B2, vitamin C, and vitamin E all have the effect of reducing the occurrence of colorectal cancer. So eat walnuts, peanuts, dairy products, lean meat, seafood, etc. in moderation to supplement vitamin E; pay attention to intake of foods rich in trace element selenium such as malt, fish, mushrooms, etc.; eat foods containing monounsaturated fatty acids in moderation, such as olives Oil, tuna, etc.
❻Develop healthy living habits: On the basis of keeping our mouth shut, we must quit smoking, limit alcohol, actively exercise, ensure sleep, and develop good and healthy living habits.
Written at the end:
Rectal cancer is easier to detect early than many insidious cancers (such as pancreatic cancer). The treatment of early cancer can often achieve a "radical" effect, and rectal cancer is no exception. The untimely death of many celebrities has once again sounded the alarm for everyone. "Early detection, early diagnosis, and early treatment" is definitely not just a slogan!
