Breast cancer continues to be researched in the hopes of increasing the success of early detection, improvement on effective medical treatment and to better understand how breast cancer can be caused by inheriting faulty (mutated) genes or with mutated cells from exposure to environmental toxins. One of these suspected toxins that have been linked to cancer is sugar. Sugar consumption has tripled over the last 50 years. This excessive amount of consumed dietary sugar is said to have many negative health problems, especially cancer.
According to four different studies of mice that were each fed a different diet, not only did they find that sugar did in fact impact the development of tumors on the mammary gland but it also often metastasized.
“We found that sucrose intake in mice comparable to levels of Western diets led to increased tumor growth and metastasis, when compared to a non-sugar starch diet,” said Peiying Yang, Ph.D., assistant professor of Palliative, Rehabilitation, and Integrative Medicine.
“We determined that it was specifically fructose, in table sugar and high-fructose corn syrup, ubiquitous within our food system, which was responsible for facilitating lung metastasis and 12-HETE production in breast tumors,” said co-author Lorenzo Cohen, Ph.D.
An epidemiological study of breast cancer mortality in relation to food consumption, found there is a strong correlation in older women, between breast cancer mortality and sugar consumption. According to this study, the possible link between sugar consumption and breast cancer is insulin. Our bodies supply insulin production in response to our blood glucose level. When this regulatory mechanism is overloaded by large dietary sugar intake, the levels can become excessive. This imbalance may explain the increased risk of mammary cancer in diabetics.
