We all know that obesity is always related to diabetes, cardiovascular disease and other diseases. But if you want to say that obesity is closely related to cancer, many people will say they do not understand. In fact, a lot of scientific studies have shown that obesity can also cause cancer! Researchers from the World Health Organization’s International Agency for Research on Cancer (IARC) reviewed more than 1,000 studies on the relationship between weight and cancer risk and found that obesity increases the chance of 13 types of cancer. For both men and women, the greater the body mass index, the higher the risk of cancer. About 9 percent of cancers are associated with obesity. The study was published in the New England Journal of Medicine, the leading medical journal in the United States. Become fat, be careful of cancer all over the body The list of obesity-related cancers, in addition to the already confirmed colon cancer, esophageal cancer, kidney cancer, uterine cancer and breast cancer 5 kinds of cancer, but also added the following 8 kinds. 1, stomach cancer Excessive fat can lead to chronic inflammation, especially inflammation of the gastrointestinal tract, which can cause the stomach to secrete more stomach acid and suffer from gastroesophageal reflux. If the proximal end of the stomach is repeatedly stimulated by the refluxed stomach acid, the risk of developing cancer will rise significantly. 2, liver cancer Liver cancer is not only related to excessive alcohol consumption and viral hepatitis infection, but also related to obesity. A study of 1.57 million adults found that BMI increased by 5 per cent on a normal basis, and the risk of liver cancer increased by 38% for men and 25% for women. To calculate, BMI = weight (kg) ÷ height² (m). If not detected and treated in time, fatty liver may develop rapidly and even induce liver cancer. The development route from fatty liver to liver cancer: simple fatty liver → non-alcoholic steatohepatitis → liver fibrosis → cirrhosis → liver cancer 3. Gallbladder cancer An epidemiological survey published in the medical journal The Lancet in 2014 showed that when BMI increased by 5 for every increase on a normal basis, the risk of gallbladder cancer increased by 31%. Obese people like to eat high-fat, high-calorie, trans-fatty acid-rich food, diet disorders, prone to metabolic disorders, bile composition is increasingly viscous, and then receive the stimulation of gallbladder inflammation, prone to gallstones, further development will lead to serious complications, but also increased the risk of gallbladder cancer. 4. Ovarian cancer According to the same study, for every 5 increase in BMI on a normal basis, the risk of ovarian cancer increases by 9%. Excess adipose tissue releases excess estrogen and pro-inflammatory factors, which may be responsible for the increased risk of ovarian and breast cancer in menopausal women. 5, pancreatic cancer one of the functions of the pancreas is to digest fat, and obese people love to eat high-fat food, will cause the pancreatic burden is too heavy, in the long run, easy to induce pancreatic cancer. In addition, obesity is a risk factor for type II diabetes, and most patients with type II diabetes have lost the function of regulating the release of insulin from the pancreas, which will increase the possibility of pancreatic cancer. 6, meningioma 2015 Live Science reported a study shows that obesity is one of the risk factors of meningioma, will make the chance of meningioma up to 50%, the excess hormone released by the adipose tissue may play a role in it. 7, thyroid cancer obesity will induce thyroid cancer is the result of the interaction of a variety of hormones, such as estrogen, insulin resistance, adipokines, etc.. In addition, with the increase in weight, the size of the thyroid gland itself is also increasing. The larger the thyroid gland is, the greater the chance of cell mutation and cancer. 8.Multiple myeloma Obesity will stimulate inflammation formation and affect the regulatory cycle of bone marrow cell growth, accelerating the occurrence of genetic mutations and cancer. Weight loss is anti-cancer! In terms of the relationship between obesity and cancer, weight loss is the fight against cancer, which requires diet control and regular exercise, one without the other. 1.Adhere to regular exercise, at least half an hour of moderate physical exercise every day, and maintain the weight between BMI 22-24. 2.Healthy diet ①Limit the intake of sugary drinks, such as sports drinks, soft drinks, etc.; replace drinks with pure vegetable and fruit juices. ②Choose low-energy, low-fat food, limit the intake of high-energy food, eat more warm food and less cold food. ③Diet advocates coarse and fine, mix grains, coarse fiber food with meat, eggs, etc. ④ Dinner to “seven minutes full” as a principle, can drink soup before the meal to control the intake of food. (6) Eat less and more meals.
