What kind of cancer should be prevented in adolescence, young adulthood, middle age and old age respectively? How to prevent? Here’s the practical advice from the experts! Youth (10-20 years old): The most important thing to prevent is breast cancer The trend of breast cancer becoming younger and younger is becoming more and more obvious, breast cancer used to occur mostly in women aged 40-60 years old, but nowadays it also occurs in women in their 20s, and there are even young patients as young as 14 years old. This is related to the unreasonable lifestyle of more and more young and middle-aged women, the indiscriminate use of birth control pills, the imbalance of hormones in the body, and the abuse of cosmetics containing estrogen. Prevention means 1. Eat more cruciferous vegetables For breast cancer, diet should be low in fat and high in fiber, you can eat more fiber-rich cruciferous vegetables, such as bok choy, cabbage, cauliflower and broccoli. Animal fats and oils should be controlled. In fact, weight control is very important, at least 5 days a week exercise to maintain a normal weight and improve body resistance. 2. 1 cup of sour milk per day Drinking sour milk regularly can also prevent the occurrence of breast cancer because sour milk contains highly active lactic acid bacteria, which can interfere with the intestinal and liver circulation in the human body and reduce the absorption of fat. Therefore, in order to reduce the incidence of breast cancer, it is best to get into the habit of drinking one cup of sour milk every day. 3. Suitable lingerie The supporting effect of lingerie can protect the breast from deformation and the breast fiber from injury due to excessive pulling. Remember not to be too thick or too small. The tight and thick lingerie, poor breathability and excessive pressure on the breast fibers will affect the blood and lymph circulation, which in the long run will cause breast enlargement, and even the risk of breast cancer will be greatly increased. It is advisable to choose cotton, moderate thickness, after wearing the underwear will not leave a visible mark (size appropriate). 4. Become a mother before 30 years old Many urban women have children after 30 years old or even do not want to have children, which can also become a cause of breast cancer. A woman’s first full-term pregnancy can mature the breast epithelium, enhance the epithelial cells’ ability to resist genetic mutation, and produce a large amount of progesterone, which is beneficial for protecting breast health and “swelling” for breast tissue enlargement. It is recommended that women complete childbirth before the age of 30. Screening methods For breast cancer, young women should develop the habit of self-examination and have a breast examination on the 7th-10th day after their monthly menstruation. When breast lumps, small nodules, skin changes, nipple overflow, eczema-like changes in the breast and enlarged axillary lymph nodes are found, they should go to the hospital for further examination by a specialist. Women over 35 years of age should have regular mammograms. Youth (20-40 years old): Prevention of gastric cancer In recent years, a lot of research data shows that the incidence age of gastric cancer has an obvious trend of rejuvenation, in the past, gastric cancer was mostly found in the age group of 40 to 60 years old, but now it is mostly found in the age group of 35 to 55 years old, especially the incidence rate of gastric cancer among young people under 35 years old has shown an obvious rising trend in recent years. Generally speaking, it is related to patients’ long-term irregular diet, not eating breakfast, sometimes busy eating lunch until afternoon, and eating spicy and salted products, which will lead to stomach discomfort and stimulation of gastric mucosa, and long-term gastric ulcer will easily develop into gastric cancer. Means of prevention 1, refuse stinky tofu, salt-cured meat Stomach cancer is related to the preference for smoked, high-salt, spicy food and alcoholism, which will destroy and damage the gastric mucosa, causing gastritis, gastric ulcers and other diseases. People in Jiangsu and Zhejiang have the habit of eating pickled foods, such as moldy winter melon, stinky tofu, soy sauce chicken and salt meat, which can contain carcinogenic substances. It is very important to refuse these foods to prevent stomach cancer. In Iceland, a country with high incidence of stomach cancer, people like to eat fish and lamb, and there are even fewer fresh fruits and vegetables on the table, so the intake of vitamin C is much lower than that of other countries. Foods with high vitamin C content include kiwi, orange, tomato, chili, green vegetables, bitter melon, etc. People with high risk of stomach cancer may want to consciously consume more of the above-mentioned foods, but it is not recommended to supplement vitamin C with drugs. 3. Two treasures for Shandong people to prevent stomach cancer On the table of Shandong people, garlic and green onion are definitely indispensable, which are not only locally abundant but also one of the reasons for the low incidence of stomach cancer in Shandong. These two foods are not only locally abundant, but also one of the reasons for the lower incidence of stomach cancer in Shandong. Garlic extract can reduce the content of carcinogenic nitrite, while onion is rich in propylene sulfide, which can inhibit the conversion of nitrite to nitrosamine by gastrointestinal bacteria, blocking the carcinogenic process. Screening methods Timely gastroscopy in case of stomach discomfort can help early screening of the disease. Middle age (40-60 years old): Prevention of intestinal cancer The incidence of colorectal cancer ranks 5th in China and is increasing at a rate of 4.2% per year. What is more noteworthy is that the number of colorectal cancer incidence in China has exceeded that of the United States, and the median age of onset of patients is about 10 years earlier than that of Europe and the United States, and young patients are more common than those in Europe and the United States. Prevention means 1.More meat and less fiber will cause trouble As our living standard improves, we eat more and more fine things, in fact, in the process of refining, we have lost many useful things, among which the most important one is fiber. Once you eat little fiber, feces stay in the body for a long time, increasing the stimulation of carcinogens on the intestinal tract, which is very unfavorable. 2.Three kinds of high-fiber fruits and vegetables every day The diet structure of many colon cancer patients is unreasonable, high protein, high calorie, low fiber, eating too fine, easy to produce constipation, the stool stays in the intestine for too long, the toxins in it will be more easily absorbed by the intestine, thus causing lesions. Insist on eating at least three high-fiber fruits and vegetables every day, such as celery, broccoli, leeks, mushrooms, sweet potatoes, corn, apples, etc. The incidence of colorectal cancer among white-collar workers is increasing rapidly, which has a lot to do with sedentary and little exercise. A new study published in the British Journal of Cancer found that regular exercise can significantly reduce the risk of bowel cancer. Thirty minutes of exercise a day can reduce cancer-prone intestinal polyps by one-third. At least thirty minutes of moderate intensity exercise, such as brisk walking, should be performed daily to slightly feel some big breaths. Screening methods 1. Seeing blood in stool can be self-checked: Early colorectal cancer with blood in stool can be easily confused with hemorrhoids, the blood in stool of the former is usually dark red, and there will be mucus attached to the surface of stool in addition to blood during defecation. Sometimes, there is always the urge to defecate for a short period of time, but no stool is passed out except for a small amount of blood or mucus. It can be distinguished from the bright red blood in the stool of hemorrhoids. 2.After 30 years old, you should do colorectal cancer screening once a year, and you can choose rectal finger examination and colonoscopy. Elderly (over 60 years old): lung cancer prevention Since the 1970s, the incidence of malignant tumors in China has continued to rise, of which lung cancer has become the first cause of cancer death in China, and smoking has been proven to be one of the main causes of lung cancer at home and abroad. Data from the Beijing Municipal Health Bureau show that from 2001 to 2010, the incidence of lung cancer in Beijing increased by 56%, with an average annual growth rate of 2.4%. Preventive measures 1. Quit smoking The risk of lung cancer among smokers and those who passively inhale “second-hand smoke” increases by 20% to 30% compared with other people. Moreover, the earlier the age of smoking, the longer the number of years of smoking and the greater the amount of smoking, the greater the risk of developing lung cancer. A person who smokes for 20 years and quits at age 40 still develops lung cancer at age 70. You can’t complain, why do you still get cancer after quitting smoking? The real situation is that quitting smoking does not eliminate the adverse effects of the first 20 years of smoking, but quitting smoking extends your healthy life by 30 years. 2. Stay away from kitchen fumes Kitchen fumes are the scourge of lung adenocarcinoma in women. High temperature fumes from cooking will produce a lot of cancer-causing fumes, which will irritate the eyes and throat for a long time and cause damage to the cellular tissues of the respiratory system and lead to lung cancer. It is best to turn on the range hood 1 minute before frying and turn it off after 3~5 minutes of frying. 3, eat more beans A recent survey by the Japanese Ministry of Health, Labour and Welfare shows that: men who regularly consume soy products can reduce the risk of lung cancer. Soybeans are rich in antioxidants isoflavones, and their anti-cancer effects are unquestionable. You can eat soybean grains directly, such as cooking soybeans with some diced radish. For soy products, and vitamin D-rich food together, but also has a good calcium supplement effect, such as meat, fish, eggs, shrimp, etc.. 4.Laughing to prevent lung cancer Since the beginning of 1999, a study on lung cancer incidence factors in Xi’an region found that long-term mental depression is a risk factor for lung cancer. Cultivating good personal character and emotion may have a role in reducing the incidence of lung cancer. “People’s immune system is low under depression, anger and sadness, and they are prone to grow malignant tumors at this time.” You may want to ask yourself if you can have a good laugh at morning, noon and night every day, and always remind yourself to keep a good mood. Screening methods It is recommended that people over 40 years old with a long-term smoking history and a family history of lung cancer should have an annual lung examination, preferably a low-dose spiral CT. To help people discover potential lesions as early as possible for a better chance of cure, eHealth, a strategic partner in tumor screening and prevention, has now launched the “3650 Precision Health Checkup Package”. “In addition to the 10 standard regular packages, low-dose spiral CT, the world’s leading robotic capsule gastroscopy and other value-added services are offered. Among them, the low spiral dose CT can detect the lung in three dimensions without missing any corner, and lung tumors of about 0.5cm in diameter can be clearly detected and imaged, and its lung cancer detection rate is about 10 times that of chest X-ray, which is more conducive to the detection of early lung cancer. The NaviCam capsule gastroscope used in this package only requires the examinee to swallow a small “capsule”, which is as simple as taking medicine, painless and non-invasive, without discomfort, and provides a comprehensive understanding of your stomach in 15 minutes, leaving no place to escape.
