1, the king of cancer – pancreatic cancer causes: westernized diet Clinical epidemiological studies over the past decades have found that pancreatic cancer is more likely to occur in middle-aged and elderly people, and the incidence rate of pancreatic cancer in the West is much higher than that in other regions. Currently, the incidence rate of pancreatic cancer in Shanghai has reached as high as 12-14/100,000 and is on the rise. Smoking is currently the only recognized risk factor with a definite effect on the development of pancreatic cancer. A large number of prospective studies and case-control studies abroad have shown that the risk ratio of pancreatic cancer patients who smoke to non-smokers is 1.6-3.1:1, and the amount of smoking is positively correlated with the incidence of pancreatic cancer. Therefore, the importance of quitting smoking cannot be overstated. You Jie, Department of Traditional Chinese Medicine, Ninth People’s Hospital, Shanghai Jiaotong University School of Medicine The increasing westernization of dietary habits, excessive intake of sweets, meat and fried foods, and too little intake of vegetables, fruits and coarse grains are closely related to the increasing incidence of pancreatic cancer. The high-fat, high-protein “big fish and meat” diet will stimulate the gastrointestinal tract to release cholestrol and other hormones, increasing the sensitivity of the pancreas to carcinogens and accelerating the time of normal cell mutation. At the same time, the amino acids and proteins in food will be decomposed into heterocyclic aromatic amines that can induce pancreatic cancer when fried at high temperatures, and frequent consumption of fried food will increase the risk of pancreatic cancer. Therefore, the general public should start by adjusting their dietary habits, not eating burnt and baked foods, minimizing the consumption of high-fat, high-oil, fried and salty foods, while keeping cereals, beans, sweet potatoes and other coarse grains as important dietary supplements, consuming more fresh vegetables and fruits every day, and increasing the intake of fiber, carotene, vitamin E and essential minerals in the diet. Since pancreatic cancer does not have “specific symptoms” in its early stages, once people experience abdominal pain, indigestion, or other symptoms, it is important to take care of them. Once people have symptoms such as abdominal pain, indigestion, back pain and sudden blood sugar abnormalities, we recommend that they should go to the pancreatic surgery department of a specialized oncology hospital in addition to internal medicine, orthopedics and endocrinology to rule out the possibility of pancreatic cancer and then go to the relevant departments for further treatment. Don’t delay the disease due to the treatment of “symptom but not cause”. 2. Female killer – cervical cancer causes: unclean life” There are two major “red-faced killers” for women, one of which is cervical cancer. Nowadays, more and more young unmarried women are infected with HPV virus due to unclean life and unfortunately suffer from cervical cancer as a result. Behind the alarmingly high incidence rate, we found that there are two age groups with high incidence of cervical cancer in Shanghai: one is 25-45 years old and the other is 55-65 years old. For example, less than 10% of cervical cancer patients younger than 35 years old came to the Cancer Hospital of Fudan University more than 10 years ago, but now 15%-20% of patients in this age group. Thus, we find that the number of young cervical cancer patients is increasing year by year and the trend is gradually getting younger. To keep away from cervical cancer, young women should be clean, not to have sex too early, and not to have multiple sexual partners, so as to reduce the chance of high-risk HPV virus and build up a green life barrier for themselves. In addition, TCT (cervical exfoliation cytology) is a powerful tool for early detection of cervical cancer, which involves placing a speculum in the vagina of the screened person and using a brush to remove cells from the surface of the cervix and the cervical canal. Cell morphology. As an annual screening test, cytology is non-invasive, affordable, easy to perform and very sensitive, while the positive detection rate is very high. Therefore, we recommend that those who have had sex too early, have too many sexual partners; have a family history of cervical lesions, cervical cancer, gynecologic tumors, and women who have had sex for more than three years or have had sex over the age of 21 need to have TCT once a year. 3.One of the possible causes of lymphoma: long-term staying up late Nowadays, we often see some young white-collar workers around us staying up late all night due to heavy work pressure, and even sudden death occurs. At the same time, we also find that some young people unfortunately suffer from lymphoma, and some of them are already in advanced stage when diagnosed. Facing the trend of lymphoma becoming “younger”, where should we go from here? Currently, the incidence of lymphoma in Shanghai is higher than the national average, about 10-11 per 100,000, which is close to the Western level. The higher incidence of lymphoma among people in developed areas is, to some extent, closely related to modern lifestyles. The increasing pace of work and excessive work pressure may induce the disease if young and middle-aged people cannot release their psychological pressure in time. From the results of epidemiological investigation and research, the occurrence of malignant lymphoma is related to ethnicity, genes, living environment, and the tendency of family occurrence. Studies have shown that the occurrence of malignant lymphoma may be related to viral infection, and the incidence of malignant lymphoma is increased in people with immune deficiency. Office white-collar workers are not only under great work pressure, but also need to work overtime frequently. Some people are obviously severely physically overstretched due to frequent late nights and overtime work and long hours in an environment of electronic radiation or radioactivity, leading to long-term overwork and a decrease in the immune function of the body. Along with the weakened immune system, the chance of virus infection also increases, so lymphoma is more likely to “take advantage of the situation”. For this reason, prevention of lymphoma should start with good living habits, such as not staying up late for a long time, keeping a good attitude to cope with stress, and strengthening physical exercise to enhance physical fitness; eating more green and healthy food. In addition, because the early manifestation of lymphoma is insidious, it is more difficult to be detected. The most obvious is the painless swelling of lymph nuclei in the neck, armpit or groin. Therefore, when painless swelling of lymph nodes occurs in the body, one should go to a regular hospital for biopsy examination in time to gain valuable time for early detection.
