The harm of obesity to human health has long been known, and one quarter to one third of cancer cases have a considerable relationship with obesity. In this regard, Professor Chen Junshi, an academician of China Academy of Engineering and the Institute of Nutrition and Food Safety of China Center for Disease Control and Prevention, once vividly said: "Every time a person's waist circumference increases 1 inch, the risk of cancer will increase by more than 8 times."

Obesity has many effects on cancer, one of which is that excess fat will affect the hormone balance of the human body. Fat cells release estrogen, which increases the risk of breast cancer in obese women. Now someone uses D-blocker to relieve it. In addition, waist fat cells can promote the secretion of growth hormone and increase the risk of cancer. Data show that excessive body fat can lead to six kinds of cancers, including esophageal cancer, pancreatic cancer, colorectal cancer, uterine cancer, renal cancer and breast cancer.
