The incidence of rectal cancer is increasing year by year, and our health is seriously threatened. Rectal cancer occurs in people after 40 years old, and most of the main symptoms include blood in the stool. There are many causes of blood in the stool, which are generally divided into two categories: benign diseases (hemorrhoids, anal fissure, inflammatory bowel disease) and malignant tumors (rectal cancer, colon cancer, etc.), among which hemorrhoids are the most common benign disease causing blood in the 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 someone in the direct blood line suffering from rectal cancer.
2.People with a history of malignant tumors, such as breast cancer.
3.People who have suffered from colorectal cancer before.
4.Other colorectal diseases, such as rectal polyps, chronic rectal inflammation.
5.People above 40 years old in areas with high incidence of colorectal cancer (such as Guangzhou, which ranks first in the incidence of colorectal cancer among 31 tumor registry sites in China).
6.People with high fat and high protein diet.
7.People who have received radiation treatment to the pelvis.
8.In addition, smoking and obesity may also have some relationship with rectal cancer.
Doctors suggest that the above-mentioned people should have fecal occult blood examination every year, usually three times, and those who are positive should be further examined, i.e. colonoscopy, and if necessary, rectal tissue biopsy should be taken.
Rectal cancer favors “heavy taste”, these triggers should be avoided
1.High-fat and low-fiber dietary habits
Bad dietary habits are important factors to trigger rectal cancer, especially high-fat and low-fiber dietary habits. High-fat food will increase methylcholanthrene in stool, leading to the increase of bile acid secretion, while insufficient intake of dietary fiber leads to the increase of stool residence time in the intestine, resulting in the increase of intestinal absorption of carcinogens, which increases the chance of cancer, thus increasing the risk of rectal cancer. In order to prevent rectal cancer, we must reduce the intake of fat in daily life, and at the same time, we must have many fresh vegetables and fruits, especially foods rich in dietary fiber.
2.Sitting still
Being sedentary is also one of the three major habits that are prone to induce rectal cancer, which requires special vigilance. On the one hand, sedentary will lead to slower digestion, decomposition and excretion of ingested fats and proteins, which will increase the risk of rectal cancer due to the prolonged stay of intestinal metabolites in the intestine, thus increasing the stimulation time of harmful substances to the intestine; on the other hand, sedentary will lead to slower blood circulation in the pelvis and lumbosacral area due to pressure, which will easily induce diseases such as hemorrhoids and constipation, and also reduce the immunity of the body, which will also increase the risk of rectal cancer. This will also increase the risk of rectal cancer. In order to prevent the occurrence of rectal cancer, we must change our sedentary lifestyle habits in daily life.
3.Bringing in stool
As the pace of life continues to accelerate and the pressure of life and work increases, many people often have to hold their urine and stool for a long time before solving them, which is an important factor that induces rectal cancer and requires special vigilance. This bad life habit is an important factor to trigger rectal cancer, which requires special vigilance. Stool and urine contain many carcinogenic substances, and frequent holding of stool and urine will cause these carcinogenic substances to stay in the intestine for a long time, which will increase the absorption of these carcinogenic substances in the intestine, thus increasing the risk of rectal cancer. To prevent rectal cancer, we must change this habit in our daily life and solve it in time when we have the urge to urinate or stool.
Think about it, how many people are shot in the causes that induce rectal cancer? If, unfortunately, all these triggering factors of rectal cancer are present, how to determine whether you are suffering from rectal cancer?
Hemorrhoids won’t turn into rectal cancer, but can provide cover for it
”Will hemorrhoids evolve into rectal cancer?” This question is of great concern to people.
In fact, hemorrhoids and tumors are two different diseases in nature. Hemorrhoids are soft venous masses formed by the expansion and flexion of the veins under the skin at the end of the rectum (that is, inside and outside the anus). In contrast, tumor is the transformation of colorectal mucosal cells into cancer cells, and current research has not found any precedent of hemorrhoids becoming rectal cancer.
However, some patients say, “How did hemorrhoids become rectal cancer when they used to be hemorrhoids?” 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 identify rectal cancer and hemorrhoids at an early stage
So how to distinguish between hemorrhoids and rectal cancer without delaying the disease? Let’s read on.
1.Difference between blood in stool
Blood in stool from hemorrhoids is usually bright red and floats on the surface of stool, and it stops on its own after defecation. In rectal cancer, the blood is darker, blood and stool are often mixed together, and in many cases, mucus or pus is also mixed.
2.Difference in defecation habits
Rectal cancer can cause changes in bowel habits, such as thinner stools, more frequent or alternating constipation and diarrhea. But hemorrhoids will not cause these changes.
Rectal cancer is often accompanied by other symptoms
1. Painful defecation: about 50% of rectal cancer patients have pain when defecating, the degree of which may be mild or severe.
2.Abdominal pain: some patients have abdominal pain as a prominent symptom, while others have paroxysmal colic with abdominal distension.
3.Lack of energy, anemia and abdominal mass: Due to the consumption of tumor, patients may also have systemic symptoms such as anemia, weakness, weight loss and low fever. In case of hemorrhoid, it rarely causes these discomforts.
Doctor’s advice: once you find the above symptoms, you should go to hospital for examination immediately. Generally speaking, rectal finger examination 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 cancer
Whether you are a high-risk group for rectal cancer or not, it is responsible for your health to follow these suggestions below
1.Eat less or no food rich in saturated fat and cholesterol: red meat (pork, beef, lamb), oil, animal offal, fried food, etc.
2, eat less or do not eat pickled foods: our scholars also found that those who often eat pickled foods, rectal cancer chances increase, so we try to eat less or not.
3.Limit oil: Vegetable oil, including peanut oil, soybean oil and canola oil, is 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, etc. In the premise of maintaining the same amount of staple foods, replace fine grains with some coarse grains.
5.Supplement vitamins and trace elements: Our scientists found that selenium, calcium, carotene, vitamin B2, vitamin C and vitamin E all have a role in reducing the occurrence of colorectal cancer. So 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 foods rich in trace elements of selenium; moderate consumption of foods containing monounsaturated fatty acids, such as olive oil, tuna, etc.
6.Cultivate healthy habits: On the basis of controlling mouth, we should also quit smoking and limit alcohol, actively exercise, ensure sleep and cultivate good and healthy habits.
Compared with many insidious cancers (such as pancreatic cancer), rectal cancer is relatively easy to be detected at an early stage. The treatment of early stage cancer can often achieve the effect of “cure”, and rectal cancer is no exception. The premature death of many celebrities has once again sounded the alarm that “early detection, early diagnosis and early treatment” is definitely not just a slogan!
