Link Between Cancer and Obesity Argues for More Aggressive Treatments

Scientists are connecting greater cancer risk for obese patients to bacteria residing in the digestive tract

Los Angeles, CA, July 12, 2013 – Michael Feiz, M.D., F.A.C.S believes that it’s becoming clear that the prevention of cancer is another major benefit of healthy, long-term weight loss that can be fostered by such bariatric procedures as the sleeve gastrectomy and the Lap Band.

Lapband (Laparoscopic Gastric Banding) Before and After - Dr FeizObese people are used to hearing warnings regarding heart disease, high blood pressure, diabetes, and stroke; however, the link between obesity and cancer is often left out of the discussion. That may change somewhat given new evidence recently revealed in the highly respected scientific journal, Nature. A new article describes how a team of researchers, led by Eiji Hara of the Japanese Foundation of Cancer Research, established clear links between obesity, liver cancer, and some of the microbes that make their home in the gastro-intestinal tract. The study shows that obesity causes the microbes to secrete an acid that appears to harm DNA and thereby increases the likelihood of tumors. Since the evidence indicates that ending obesity would also stop this process, Dr. Feiz believes cancer prevention is an important factor to consider when contemplating a gastric sleeve, band, or bypass operation.

The Nature article is only the latest in a seemingly endless procession of data points regarding the many health risks associated with obesity and the numerous benefits of reversing it. For all the discussions about the various factors associated with Lap Band vs gastric sleeve surgery, it’s becoming clear that ending or reducing obesity is one of the most important health steps a person of any age can take. People who have tried reduced calorie diets and increased vigorous physical activity without success, but who are determined to do whatever it takes to shed their excess weight, should contact Dr. Feiz & Associates to inquire about attending a free educational seminar.

Dr. Hara’s study focused on a number of genetically modified mice who were exposed to carcinogenic substances similar to the pollutants that often effect humans. The mice included a number of animals who had been made obese with a high fat diet, and a number of slimmer rodents. After a period of several months, only 5 percent of the more lean mice had developed cancer, but 100 percent of the obese mice had become afflicted. The diseased mice were found to have a significantly higher amount of a DNA damaging secretion, deoxycholic acid, in their blood.

The process by which obesity becomes entrenched and, in turn, leads to other illnesses is a highly complex one, but bariatric procedures undertaken by highly skilled surgeons have been proven time and again to be highly effective and very safe. As one of the most respected weight loss surgeons in the nation, Dr. Feiz’s effectiveness is without question, and his compassionate bedside manner has been praised by countless grateful patients.

  • A new set of studies out says bariatric surgery completely reversed Type 2 diabetes in 75 percent of patients. In cases where the bariatric surgery was more extreme, the percentage for people who completely reversed the disease rose to 95 percent. In fact, the results were so immediate; doctors say some people were able to stop taking insulin as early as three days following the surgery.

  • Surgical weight loss procedures including gastric bypass and gastric banding surgery continue to be the most popular options for morbidly obese patients.

  • Even though weight loss can be as simple as a healthy diet and consistent workout regimen for many people, it is a struggle for those who are severely overweight or medically obese. Even though some obese patients are successful with weight loss programs that include bariatric surgery, a change in attitude and educating oneself about food and nutrition can also help the individual lose the weight for good. Addressing issues such as a food addiction, poor eating habits and getting off the yo-yo diet cycle can all help to increase chances of success with any weight loss program.
