In China, cancer has become the leading cause of death, and morbidity and mortality are still rising, posing a huge threat to public health. According to statistics, more than 2.8 million people died of cancer last year in China, with an average of 7,500 people a day.
As we all know, the prevention and treatment of cancer is closely related to life. The prevention of cancer is particularly important. For this reason, medical experts from all over the world are conducting in-depth and multi-angle research.
In 2016, what are the latest findings that are worth knowing?
We have summarized the top ten new discoveries that have been publicly reported in the media in 2016 and are closely related to life. I hope to help you.
Walking every day can prevent multiple cancers
The latest study by the British Charity Walker Association and the Macmillan Cancer Aid Center found that walking 1.6 kilometers a day and walking within 20 minutes has obvious benefits for the treatment of breast cancer, prostate cancer and intestinal cancer, up to 50. % death risk.
Previously, a number of recent international studies have clearly pointed out that walking can enhance immunity, improve endocrine, regulate hormone levels, and have outstanding effects in preventing cancer and cancer.
Review
When walking, the body should be straight and the eyes should be able to look straight ahead, pay attention to the shoulders to relax, do not deliberately maintain a fixed walking position, so as to avoid discomfort in the neck and shoulders. Before walking, you should do moderate warm-up exercises, start slowly, wait until the feet are a little hot, and then increase the speed. When you get to the terminal, slow down slowly, don't stop right away. If you choose to walk after dinner, you should do it within half an hour after meals to two hours before bedtime.
Unscientific use of vegetable oil or carcinogenic
According to Singapore’s “Lianhe Zaobao†on August 10, a recent study in Australia found that the incidence of lung cancer among women in Asian countries is high, probably because vegetable oil is working.
Studies have found that vegetable oils are highly unstable, and at high temperatures, they may release substances harmful to the nerves, causing DNA to mutate and cause cancer. Cheap vegetable oils extracted from plant seeds contain large amounts of polyunsaturated fats compared to animal oils, olive oil and coconut oil.
When these fats exceed 180 degrees, they produce highly toxic, cancer-inducing chemicals.
Review
In fact, normal vegetable oil itself is not carcinogenic, and the cause is mostly the problem of cooking. Vegetable oil contains unsaturated fatty acids that are not heat-resistant. When exposed to high temperatures, it is easy to produce carcinogens such as acrolein and other aldehydes. In general, less frying, more cooking, and good cooking habits are more helpful in preventing cancer.
Eat 3 servings of nuts per week to prevent colon cancer
A recent study in South Korea also found that a nut-rich diet can reduce the chance of colon cancer in an individual.
The study was published at the annual meeting of the American Association for Cancer Research on April 18.
According to Aesun Shin, assistant professor of preventive medicine at Seoul National University's School of Medicine, people who eat no less than 3 nuts a week are 69% less likely to develop colon cancer than those who do not. Women's risk of getting nuts is reduced by as much as 81%.
Review
Some of the nuts, including cellulosic and antioxidants, can reduce the risk of colon cancer. In addition, "three high and one low" foods, such as high protein, high fat, high calorie, low cellulose foods should be eaten less.
Cruciferous vegetables prevent breast cancer
Researchers at Oregon State University have found that a compound rich in broccoli and other cruciferous vegetables can slow the growth of breast cancer cells, especially for early breast cancer patients.
In the new study, the researchers used 45 breast cancer patients to allow some subjects to take a placebo, while others took a dose of sulforaphane supplement.
The sulforaphane contained in the supplement is equivalent to a small cup of broccoli seedlings per day. It is generally believed that the broccoli seedlings contain more sulforaphane than the mature broccoli.
The team reported in a new issue of the Journal of Cancer Prevention Research that the results showed that taking a sulforaphane supplement reduced the growth index of breast cancer cells, suggesting that this compound may help slow the growth of cancer cells. .
Eating saury can reduce the risk of liver cancer
According to a survey released by the National Cancer Research Center of Japan, people who eat squid, saury, sardines, and other blue-backed fish and squid have a risk of developing liver cancer compared with those who do not eat these fish. 40% lower.
Fish with blue backs such as squid are collectively referred to as "green fish" in Japan. These fish have very high levels of unsaturated fatty acids.
The researchers conducted long-term follow-up investigations on about 90,000 residents aged 45-74 in Japan.
The researchers recorded the amount of eight species of fish, such as sardines and squid, which were selected from the same species. The eight species selected were all higher in unsaturated fatty acids.
As a result, it was found that a group of people whose total fish intake reached about 70.6 grams per day had a 36% lower risk of liver cancer than a group of people who only took about 9.6 grams per day.
Eat tomatoes regularly to prevent skin cancer
According to a recent study by the Leibniz Institute of Environmental Medicine in Germany, eating tomatoes often reduces wrinkles and prevents skin cancer.
The researchers found that volunteers who ate tomatoes every day had significantly less wrinkle-related genes.
Researcher Jane Kutman said the study confirmed that eating tomatoes can effectively resist the adverse effects of UV radiation, reduce wrinkles and prevent skin cancer.
Experts from the British Dermatology Association reminded that in addition to improving the diet, in order to better protect against UV rays, the sun should not be more than 40 minutes a day, and must be sunscreen.
Eating fish often reduces the risk of pancreatic cancer
The National Cancer Research Center of Japan published a report in the new issue of the American Journal of Clinical Nutrition, which stated that its research showed that the intake of fish fatty acids called “n-3 polyunsaturated fatty acids†can reduce the risk of pancreatic cancer. Up to 30%, the main reason may be that this type of fatty acid can reduce inflammation of the pancreas.
Experts say that pancreatic cancer is difficult to detect due to early symptoms, and even the five-year survival rate of patients with pancreatic cancer is only 6%, becoming a veritable "king of cancer". The findings of this study are for people with high risk of pancreatic cancer. To prevent pancreatic cancer from finding a breakthrough.
Review
According to previous research reports, the occurrence of pancreatic cancer is related to chronic inflammation, and the "n-3 polyunsaturated fatty acids" from fish have anti-inflammatory and immune-modulating effects, which may reduce the risk of pancreatic cancer. .
Eating mango reduces the risk of cancer
Scientists at the Texas Research Center in the United States have found that mangoes are very beneficial to the human body. Eating more mangoes can help reduce the risk of cancer. Scientists have found that although mango contains 3-4 times less antioxidants than pomegranate and blackberry, its flesh contains polyphenols, which prevent and prevent the formation of cancer cells in humans. It is worth noting that polyphenols do not cause side effects.
Significant weight gain increases cancer risk
A recent study by the University of Manchester in the United Kingdom showed that if the increase in body weight over a period of time would increase the risk of cancer, men's risk increased in this regard.
The researchers found that men whose body mass index increased from 22 to about 27 had a 50% higher risk of cancer compared with those with normal weight. If the body mass index of women increased from 23 to about 32, the risk would be Increase by 17%. The body mass index is a commonly used indicator for measuring the degree of fatness and thinness in the world. It is calculated by dividing the body weight (kg) by the square of the height (m).
It is generally believed that this index is overweight for over 25 and obesity for more than 30.
Review
The industry's research on obesity and cancer has also previously confirmed that overweight or obesity is associated with the risk of cancers such as colorectal cancer, pancreatic cancer, breast cancer, and uterine cancer. Therefore, weight loss should be one of the effective ways to prevent cancer, which deserves attention from overweight people.
Eating white rice often increases lung cancer risk
The most controversial cancer news this year is a new study from Texas State University. The results of this study show that people who eat white rice, white bread, and other foods with high glycemic index (GI) can increase the risk of lung cancer. %.
It is understood that in this study, the researchers compared 1,905 lung cancer patients with 2,413 healthy people and found that patients with the highest daily glycemic index (GI) had a higher risk of lung cancer (higher than 49). %); High GI smokers also have a 31% higher risk of lung cancer than low GI smokers.
The paper concluded that the total carbohydrate quality of the diet affects the risk of cancer, and the high glycemic index is associated with lung cancer. Foods with high glycemic index include white rice and white bread.
Review
Eating rice without a normal diet will not lead to lung cancer. This study only proves that foods with high glycemic index are related to the occurrence of lung cancer. It is not easy to understand that eating white rice can cause cancer. However, domestic studies have also confirmed that pre-diabetes can lead to increased risk of cancer, especially with the increased risk of liver cancer, endometrial cancer, gastric cancer, colorectal cancer, pancreatic cancer and breast cancer, so scientific diet, scientific control Sugar is an effective way to prevent cancer!
