30 percent of cancer deaths are due to fat accumulation

Hypertension, diabetes, dyslipidemia and other life chronic diseases, are closely related to visceral fat hoarding. But it doesn’t just affect these diseases. 

Fat hoarding is linked to colorectal cancer, partial esophageal cancer, endometrial cancer, pancreatic cancer, kidney cancer, breast cancer, liver cancer and other cancers, according to the Obesity Society’s Obesity diagnosis Guide 2016.

It’s not just the Japan Obesity Society that makes such claims. In a 2007 report, the World Cancer Research Fund (WCRF) and the United States Agency for Cancer Research (AICR), Indeed mentioned that obesity will lead to esophageal adenocarcinoma, colorectal cancer, kidney cancer, postmenopausal women breast cancer, endometrial cancer and other cancers increased risk. 

So what percentage of all cancers are caused by obesity? One famous paper looked at Americans dying of cancer to speculate on the cause of the disease. This paper, published in 1981, combines the results of a huge survey conducted before to analyse and investigate the incidence of cancer caused by various types of cancer. 

35% of cancers are caused by eating habits, 30% are caused by smoking, followed by viral or bacterial infections, alcohol consumption, and so on. 

In 1996, the Center for Cancer Prevention of Harvard University in the United States did the same research. Among the causes of cancer deaths, 30% were caused by eating habits and obesity as adults, and 30% were caused by smoking. Other reasons in order are lack of exercise, drinking, and so on. 

Diet and obesity account for between 30% and 35 of the causes of cancer, and the results are truly startling. 

A large study of colorectal cancer in Japan reported that men with a BMI of 27 or more were 1. 4 times more likely to develop colorectal cancer than those with a BMI of less than 25. 

Please take out your most recent health report and make sure your waistline is standard and if so, how much. This is for your health.

Obesity also increases the risk of many cancers! 

Numerous medical studies at home and abroad have shown that at least 12 types of cancer have been found to be linked to obesity, and (National Cancer Institute), the National Cancer Institute, also points out that obesity increases the risk of cancer. In particular, esophageal cancer, pancreatic cancer, colorectal cancer, breast cancer, endometrial cancer, renal cancer, thyroid cancer, biliary tract cancer and so on. 

A study has shown that every 5 kg / m2 increase in body mass index (Body Mass Index, BMI),) increases the risk of biliary system cancer by 56% and the risk of rectal cancer in men by 9%. The risk of developing breast cancer after menopause increased by 11% for every 5 kg gain in weight among adult women who had never used the hormone therapy. In adult women, for every 0.1 increase in the waist-to-hip ratio, the risk of endometrial cancer increased by 21 per cent. 

There are various hypotheses that explain the increased risk of cancer due to obesity. 

In the case of esophageal cancer, in recent years, it has been found that the cell type of esophageal cancer changes from squamous epithelium to glandular cell carcinoma, one of the reasons is that more and more patients are induced by obesity-related gastroesophageal reflux. Obesity also causes cells to secrete hormones that induce an inflammatory response in the body, putting obese people at higher risk of developing esophageal adenocarcinoma than normal people. 

Excess fat intake increases the production of steroids and hormones, such as the estrous hormone (Estrogen) and the androgen (Androgen), which are closely associated with breast, endometrial and prostate cancers. For postmenopausal obese women, a reduction of 10kg without weight loss could reduce the incidence of breast cancer by 50%, since obesity and excess fat intake increase breast fat tissue and estrus receptors, which in turn cause breast cancer.
