Study: High Fructose Intake Increases Risk of Breast and Lung Cancer

You need to be little cautious if you love eating western diet rich in high sucrose and fructose levels. As per a new study, researchers have found increase in risk of developing breast and lung cancer in women who eat more of western diet including sugary content. Researchers from the University of Texas MD Anderson Cancer Center conducted the research on mice and found increased risk of breast and lung cancer in mice who consumed high sucrose and fructose levels. You must be thinking that sugar is needed to generate energy, the study shows that refined sugar and fructose affects the body differently.

Researchers said that high levels of fructose in table sugar and high-fructose corn syrup, and used in a high percentage of food items, encouraged breast tumor growth, and helped it spread. According to the Dana-Farber Cancer Center, many studies conducted in the past have shown link between dietary sugar and several types of cancer. Several studies even resulted out connection between sugar and inflammation that can lead to development of cancer. Dr. Lorenzo Cohen, a professor of palliative, rehabilitation, and integrative medicine at MD Anderson, said recent study found impact of dietary sugar on mammary gland tumor development in multiple mouse models, along with mechanisms that may be involved. The study found that fructose, in table sugar and high-fructose corn syrup, is responsible for facilitating lung metastasis and 12-HETE production in breast tumors.

By the end of the research, about 50 and 58% of mice on a sucrose-enriched diet developed mammary tumors by the time they were six months old, but just 30% of mice on a starch-control diet had measurable tumors at the same age. The study conducted on mice has found that the refined sugar and fructose had an effect on a metabolic process called 12-LOX, which is responsible for the growth of cancer. The latest study bolsters the previous research, which suggests that about 66% of all cancers are preventable, in that they are caused by lifestyle choices like smoking, tobacco use, lack of exercise and unhealthy diet.

In a statement provided to UPI, pharmacists in Oregon are now permitted to prescribe birth control pills to qualifying women as part of a wave of new state laws for 2016. Oregon is the first U.S. state to put such a law into effect, with California reportedly looking to follow suit. A doctor's approval is no longer needed for a supply of pills, although experts urge women not to overlook preventative health care in the form of doctor visits.

ModernReaders report said, a study from the University of Texas MD Anderson Cancer Center showed that fructose and sucrose, which are found in table sugar and corn syrup, speed up breast tumor growth, also making it spread to other parts of the body. Both are also key ingredients in many foodstuffs that comprise traditional Western diets.

This study adds to others that have linked dietary forms of sugar and Western diets in general to various types of cancer, and also backs up studies that have separately associated sugar with tumor growth. It does, however, sort of contradict studies that claim lifestyle choices, such as diet and smoking, are mainly responsible for several types of cancer.

In a statement provided to NBC Connecticut, Yet researchers say this sole factor is harder to pin down, since "sugar" is a very broadly used term.

"A lot of patients are told it doesn't matter what you eat after you are diagnosed with cancer. This preliminary animal research suggests that it does matter," said Lorenzo Cohen of the University of Texas M.D. Anderson Cancer Center, who worked on the study.
