According to a British study, compared with women, men are more likely to suffer from colorectal cancer when they watch TV for a long time. This statement is based on a comparative study, so it still has some credibility. So we must pay attention to those men who love watching TV. What are the common symptoms of colorectal cancer?
Men who watch TV for more than four hours a day may have an increased risk of colon cancer, while women who watch TV for a long time are less likely to have cancer, according to a British study.
Researchers from Oxford University, Imperial College of technology and the international cancer research center looked at the lifestyle and medical data of more than 500000 Britons, nearly 2400 of whom had cancer six years later. Data analysis shows that men who watch TV for more than 4 hours a day have a 35% higher risk of colon cancer than men who watch TV for less than 1 hour, and women who watch TV for a long time have a 11% higher risk of colon cancer than other women. However, sitting in front of a computer screen for a long time has no similar relationship with bowel cancer.
Researchers speculate that people are more likely to eat junk food, smoke and drink while watching TV than they are in front of a computer, and previous studies have shown that such behavior increases the risk of colorectal cancer. As for why men are more at risk of colon cancer from watching TV for a long time than women, further research is needed.
What are the symptoms of colorectal cancer
Altered bowel habit
The change of defecation habit is the most common symptom of colon cancer. Many patients easily confuse the early symptoms of colon cancer with general constipation, thus delaying the treatment. With the growth of intestinal tumor, fecal excretion will be hindered, which will cause the change of defecation habits.
Bloody stool
The stool blood caused by colorectal cancer is usually persistent and accompanied with mucus. At the same time, the stool will increase, sometimes only some blood or mucus will be discharged. If the tumor is far away from the anus, the incidence of hematochezia will be low. About 80% of rectal cancer patients have hematochezia.
Gastrointestinal symptoms
Gastrointestinal symptoms caused by colorectal cancer are mainly abdominal distension and dyspepsia. The abdominal distention and abdominal pain caused by colorectal cancer are mostly intermittent at the initial stage, and will gradually change to persistent at the later stage. Some patients will also have intestinal obstruction, acute symptoms of abdominal pain and exhaust obstruction. There are also chronic intestinal obstruction, such as paroxysmal abdominal pain, hyperactivity of bowel sounds, constipation, fecal blood and mucus, etc.
Abdominal mass
About half of the patients with colorectal cancer will have abdominal mass, which is caused by the adhesion of tumor mesentery and surrounding tissue. The mass is irregular in nature and has a certain degree of activity. However, it may be difficult to move in the late stage of colorectal cancer due to the high degree of tumor infiltration.
Anemia and emaciation
With the progress of the course of the disease, the patient may have chronic wasting symptoms, such as anemia, emaciation, fatigue and fever, and even bad fluid quality, often accompanied by fatigue and unexplained sudden weight loss, which is related to hematochezia, inadequate intake and excessive consumption.
How to prevent colon cancer
Adjust eating habits
At ordinary times, the proportion of coarse grains and miscellaneous grains in the staple food can be increased moderately, which should not be too fine or too refined; the habit of focusing on meat and diet with high fat content should be changed; eating less sweet and greasy food, especially the intake of animal fat, such as lard and fat meat, should be controlled. A large number of such foods will promote the occurrence of colorectal cancer.
Exercise regularly
We should keep exercising and keep the standard weight. Obesity, especially abdominal obesity, is a high risk factor for colorectal cancer. Too much abdominal fat will affect the digestion and peristalsis of the intestine. At the same time, less physical activity is also the cause of colorectal cancer. People who exercise all year round, not only have good physical fitness, but also are not easy to get cancer, including colon cancer.
Supplement dimension E on demand
Medical research has shown that vitamin E deficiency may induce colon cancer. As a natural antioxidant, vitamin E is good for all aspects of our body. Therefore, to prevent colorectal cancer, we might as well eat some foods rich in vitamin E in our daily life, such as walnuts, seafood, dairy products and so on.
Eat sweets carefully after meals
For the middle-aged and old people who have bad eating habits, we should pay special attention to prevent all kinds of colon cancer, one of the most important points is not to eat sweets in or after dinner. It's not good to overeat your dinner. If you add high calorie sweets, you will have a heavier burden on your gut. For the sake of intestinal health, we should correct the bad habit of eating sweets at dinner.
