A recent study published in the journal Cancer found an important correlation between socioeconomic status and the type of cancer that develops. The types of cancer that rich and poor people are susceptible to vary. This finding suggests that cancer is the result of the interaction of genetic and environmental factors over a long period of time. I. Cancer is the result of the combined effect of genetics and environment The family clustering of cancer has genetic defects, but the “common living environment and lifestyle” may play an important role. Modern genetics shows that cancer depends not only on genetic factors, but also on “exposure to acquired carcinogens and carcinogenic agents”. Breast cancer, lung cancer, liver cancer, esophageal cancer, cervical cancer and colorectal cancer are greatly influenced by bad living habits and environmental factors. A new study published in the journal Cancer found that there are “rich cancers” and “poor cancers”. A new study published in the journal Cancer found that there is a distinction between “rich cancer” and “poor cancer”. In the study, researchers followed 3 million cancer cases diagnosed in the United States from 2005-2009, covering 42 percent of the U.S. population and the wealthiest and poorest communities in the country. The results found a significant association between socioeconomic status and the type of cancer developed. Wealthier people were more likely to develop melanoma, thyroid, skin and testicular cancers, while poorer people were more likely to develop Kaposi’s sarcoma, laryngeal, cervical, penile and liver cancers. Why is it so? The reason is that different triggers (environmental and lifestyle habits) that lead to the occurrence of cancer will eventually produce different types of cancer. What are the poor cancers and rich cancers in China? ”Poor cancers include liver cancer, stomach cancer, esophageal cancer and cervical cancer; rich cancers include lung cancer, colorectal cancer, breast cancer, lymphoma and prostate cancer. ”Poor cancers” are related to long-term chronic infections. V. Why liver, stomach, esophagus and cervical cancers are “poor cancers”? A study in the Annals of Oncology showed that some cancers can be caused by long-term chronic infections. In our country, hepatitis B virus, Helicobacter pylori, human papillomavirus (HPV) and EBV are the most common infections and carcinogens. Infection with hepatitis B virus further evolves into cirrhosis through acute and chronic inflammation, and in a small number of patients, can eventually lead to liver cancer. Helicobacter pylori is the most prevalent type of infecting bacteria, which may trigger gastritis and peptic ulcers, and long-term infection may promote gastric cancer. The bane of cervical cancer and its precancerous lesions has been shown to be human papilloma virus infection. The high incidence of nasopharyngeal cancer is linked to EBV infection. Generally speaking, these cancers related to long-term chronic infections mostly occur in economically underdeveloped areas, where the natural environment is often harsh, nutritional conditions are poor, hygiene levels are low, and living habits are also bad, thus making them prone to such cancers. ”Why are lung cancer, colorectal cancer, breast cancer, lymphoma and prostate cancer called “rich cancers”? In terms of pathogenesis, colorectal cancer and diabetes, hypertension and coronary heart disease are influenced by associated genes, and in terms of lifestyle, factors such as high-fat diet, lack of dietary fiber intake, sedentary lifestyle, irregular bowel movement or habitual constipation are common causes. 7. Why excessive intake of high-fat food is one of the cancer-causing factors? A new study found that a high-fat diet shifts the intestinal microecology (i.e., microbial composition) – some bacteria are increased while others are decreased. The result is a lowered immune defense against bowel cancer and an accompanying increase in the incidence of cancer. VIII. Why are sedentary people more likely to develop cancer? Immune function in human body is enhanced with the increase of activity, and sedentary can make the body lack enough immune cells. A Canadian epidemiologist found that there are 49,000 cases of breast cancer and 43,000 cases of colon cancer associated with inactivity in the United States each year, and breast cancer and colon cancer seem to be the two cancers closely related to exercise. Blocking infections can effectively prevent “poor cancers” Infections and cancers are not directly causal and do not “kill” each other. If we can stop the spread of the disease and eliminate them in the cradle, we can effectively prevent the occurrence of cancer. Vaccination. According to some data, in one region, 95% of infants and children were vaccinated against hepatitis B since 1984, and the number of hepatitis B carriers dropped from 10-20% to 0.2% after 20 years, and the incidence of liver cancer was reduced by 70%-80% accordingly. Early treatment. H. pylori can be completely eradicated by combined antibiotic treatment, which not only can relieve gastritis and gastric ulcer, but also can play a good role in resisting further development of gastric cancer. Do screenings. it is important for women over 30 to have regular cervical screenings. Also protect yourself by using condoms, not having sex too early and limiting the number of sexual partners, etc. Split meals. H. pylori and other germs are highly contagious and can be transmitted through hands, food and utensils, so it is best to share meals in family life. Nine, a healthy lifestyle can prevent “rich cancer” like colorectal cancer, breast cancer and lymphoma and other “rich cancer”, there is no unique and significant causes, some people think it is difficult to prevent. However, there are some common triggers for these types of affluenza diseases – lack of food, high-fat and high-protein diet, and lack of exercise. The way to prevent it, therefore, is to establish a healthy lifestyle. This is more difficult to do than the “poor cancer” caused by chronic infections, and requires greater determination and perseverance.
