? air pollution
Inhalation of fine particulate matter (PM2.5), ozone (O3), sulfur dioxide (SO2) and other pollutants in the air will cause damage to human respiratory system, cardiovascular system and nervous system, leading to asthma, chronic obstructive pulmonary disease, myocardial infarction, stroke and other diseases.
? water pollution
Drinking or eating water containing heavy metals, nitrosamines, chloroform and other harmful substances will cause damage to the digestive system, urinary system and endocrine system of human body, leading to diseases such as gastric cancer, liver cancer, renal failure and hypothyroidism.
? soil contamination
Food chain or skin contact with soil polluted by harmful substances such as heavy metals, pesticide residues and polycyclic aromatic hydrocarbons will cause damage to human immune system, nervous system and reproductive system, leading to allergic dermatitis, Parkinson's syndrome, infertility and other diseases.
? food pollution
Intake of mycotoxins, heavy metals, carcinogens and other harmful substances in food will cause damage to the digestive system, liver and blood system of human body, leading to food poisoning, liver cirrhosis, anemia and other diseases.
In addition, infectious diseases such as tuberculosis are easy to breed in harsh and crowded environments, which are often closely related to unsanitary housing and poor environmental sanitation!
Then let's get back to the question. Is it a coincidence that 73-year-old people and their brothers and sisters were diagnosed with precancerous lesions, or is there some genetic or environmental factor between them that led to precancerous lesions?
To know the answer to this question, we must first understand what is intestinal precancerous lesions. According to the definition of National Digestive Disease Clinical Medical Center, precancerous lesions of intestine refer to pathological changes closely related to colorectal cancer, including colorectal adenoma, adenomatosis, sessile serrated lesions, traditional serrated adenoma and dysplasia related to inflammatory bowel disease. These lesions may turn into colorectal cancer under certain conditions, so timely diagnosis, treatment and monitoring are needed.
To sum up, then we can rule out the idea of infection or being infected. I sorted out the articles published in Chinese Journal of Digestive Endoscopy, and we can see that the related factors that have been verified for the occurrence of intestinal precancerous lesions are roughly as follows:
I. Genetic factors:
Genetic syndrome increases the risk of colon cancer. Some genetic mutations inherited from family generations can significantly increase the risk of colon cancer. Simply put, if there are many people in the family who suffer from intestinal cancer or precancerous lesions, the risk of other family members will be relatively high. In this case, the elderly and three brothers and sisters were diagnosed as precancerous lesions of the intestine, which may be affected by genetic factors.
Two. Colorectal adenoma:
It is generally believed that most colorectal cancers originated from adenomas, so adenomatous polyps are regarded as precancerous lesions.
Three. Age:
With the increase of age, the incidence of intestinal precancerous lesions will also increase. This is due to the long-term accumulation effect, which leads to the abnormal proliferation of intestinal mucosal cells. Like this old man, he is 73 years old, and his age may also be an influencing factor.
Four. Diet:
High-fat and low-fiber diet may be related to the occurrence of colorectal cancer. Studies have shown that people whose diets contain a lot of red meat and processed meat have a higher risk of colon cancer. There are also long-term high-fat diet, lack of exercise, smoking, drinking and other bad habits, which may also increase the risk of intestinal cancer.
Verb (abbreviation for verb) Other factors:
Schistosomiasis, pelvic radiation, environmental factors (such as molybdenum deficiency in soil) and smoking may all be related to the occurrence of colorectal cancer.
It can be seen from the above that the living environment does have a certain influence on the occurrence of intestinal precancerous lesions. However, it does not mean that all people living in harsh environment will suffer from precancerous lesions of the intestine, nor does it mean that all people living in good environment will not suffer from precancerous lesions of the intestine. This is only a statistical probability, not an absolute causal relationship.
Then, below, I will give you some suggestions for preventing and treating intestinal precancerous lesions. Don't think it doesn't matter, let's take a look ~
? Routine screening for colon cancer. Doctors suggest that the general risk group should start screening for colon cancer around the age of 45. If there are high-risk factors, screening should be carried out as soon as possible. There are many screening methods, such as fecal occult blood test, fecal DNA detection, colonoscopy and so on. Screening can find and remove polyps in time, thus preventing colon cancer.
? Improve your lifestyle. Eating more fresh fruits, vegetables and whole grains, rich in fiber, vitamins and antioxidants, is good for your health. Eating less or not eating red meat and processed meat may increase the risk of cancer. In addition, we should also pay attention to moderate drinking, not excessive. Exercise more every week to make you healthier and happier!
? Pay close attention to your physical changes. Please take good care of your health and pay more attention to observe whether there are any abnormal changes in your life. If you feel any uncomfortable symptoms, such as blood when going to the toilet, stomach discomfort or pain, sudden weight loss, etc. Don't delay, hurry to see a doctor!
These are some effective ways to prevent colon cancer. Of course, if you persist, you can't just prevent this disease. After all, many diseases can be avoided and overcome as long as we screen them in time, treat them actively and live a healthy life! So I hope you can seriously implement it and protect your health!
The article is coming to an end here ~ I believe that all the friends present here should have a clear concept of whether there is a relationship between diseases and living environment. Of course, the specific situation must be judged according to the actual situation of the individual. Finally, I hope the above article is enough to help you!
