Four high-risk cancers in the UK are highly associated with obesity

Cancer Research UK has found that overweight people are at greater risk of bowel, kidney, ovarian and liver cancer than smokersPostmenopausal women's breast and pancreas, esophagus, upper abdomen, gallbladder, uterus, thyroid and other areas of cancer, as well as multiple myeloma and meningioma are also associated with obesityThe association between obesity and cancer is only applicable to adults, and it is not that overweight or obese people must have cancer, but that the risk of cancer is relatively highabout a third of British adults are obese, according tofiguresCancer Research UK explained that there was no intention to blame people for being overweight, and the findings do not suggest a direct comparison between smoking and obesity-related cancer risks, but that both are risk factors that can lead to cancerCurrently, the number one preventable cause of cancer in the UK is smoking, followed by obesityThe number of smokers in the UK is falling year by year, while obesity rates are rising, worrying health expertsAlthough researchers have determined that obesity is associated with cancer, the physiological mechanisms that cause cancer are not entirely clearOne possible reason is that fat cells secrete more hormones and growth factors, which increase the differentiation of human cells and thus increase the risk of cancer cellslinda Balder, a disease prevention expert at Cancer Research UK,, called on the government to do more to tackle obesityThe British Medical Association argues that the government's slowness in restricting advertising of unhealthy food and drink should make the public aware that obesity, like smoking, is a significant cause of cancerSimon Stevens, NHS England's chief executive, said the NHS alone would not win the "obesity war." In addition, some people have identified Cancer Research UK's anti-cancer campaign as a suspect in shaming obese peoplealso, a study in France linked to a higher cancer risk from sugary drinks found an overall 18 percent increased risk of cancer by drinking 100 millilitres of sugary drinks a dayThe study did not suggest a causal link between drinking sugary drinks and cancer risk, but study leader Mathilde Tuvier said the link could be due to "the fact that drinking too many sugary drinks is a risk factor for obesity and weight gain, which itself is a cancer risk factor." Another reason for the association may be that certain food additives in sugary beverages are carcinogenic, such as 4-methylmedin in caramel-colored beverages.
