About one in eight USA women will be diagnosed with breast cancer during her lifetime, and these women are living longer thanks to advances in screening and treatment.
It has been found that soy is a rich source of isoflavone - a plant derived compound, which is a class of phytoestrogens that halts the growth of hormone-sensitive breast tumours. North America occupies the major market share due to high research activities on triple-negative breast cancer, buying power of patients are the major factors boosting the growth of this market during the forecast period.
Consumption of soy for women with breast cancer has been a hotly debated topic in the last couple of years but a new study conducted by Tufts University seems to provide some much-needed clarity as researchers discovered that incorporating isoflavones into one's diet may have a positive effect. In fact, for some breast cancer survivors, soy consumption was found to be tied to longer life.
But while there is no definitive way to prevent cancer, and while you can't change your genetic risk of developing the illness (about 5five to 10 percent of breast cancers are thought to be hereditary and caused by genes passed from parent to child), there are some risk factors that you can control.
The study found that women with breast cancer who engaged in the equivalent of five hours of moderate exercise per week before their diagnosis were 40 percent less likely to have a cardiovascular event and 60 percent less likely to die from coronary heart disease compared to those with a low pre-diagnosis level of exercise. ER-negative breast cancer sufferers have low survival rates. In the trial, 307 women who had been treated for early breast cancer were given the choice of following their normal diet or switching to a Mediterranean diet. Her findings are published in the journal Cancer. "Therefore, we can recommend women to consume soy foods because of soy's many health benefits", said Omer Kucuk from Winship Cancer Institute of Emory University.
And there are other unanswered questions, according to Marian Neuhouser, a registered dietician and nutritional epidemiologist at Fred Hutchinson Cancer Research Center. A weaker but significant association was also observed among women who did not undergo endocrine therapy treatment.
Even with new research, Anders says, she's still hesitate about soy.
