The study was done over a period of nine years during which the researchers conducted various follow ups with the patients.
This benefit of better survival odds was limited to women in the study with hormone receptor-negative cancers. These are some of the figures presented during the conference "Breast Journal Club - The Importance of Cancer Research", which today and tomorrow brings together in Naples some of the most important national and global experts on the disease. A weaker but significant association was also observed among women who did not undergo endocrine therapy treatment. It was revealed at the end of the research that women who consumed high proportions of isoflavones were at a lesser risk of succumbing to death by 21 percent, when compared to women who took in low amounts of the same.
A 2015 study by Toledo and Colleagues indicated that the risk of getting invasive breast cancer was reduced by 68 percent in people who consumed a Mediterranean diet supplemented with EVOO.
Her advice to women: "I would say that from all of the studies that we have, absolutely it's safe for you to get pregnant after breast cancer". The Ontario government, for instance, covers the costs of fertility preservation.
Research in Asian women has shown that soy can protect against breast cancer.
Women who've had estrogen receptor-positive breast cancer and are put on tamoxifen to prevent the cancer from coming back would have to go off the medication, due to the risk of complications to the fetus, said Narod.
While no specific diet has been proven to improve breast cancer survival, the review authors recommend at least 150 minutes of physical activity per week, including 75 minutes of vigorous exercise and around two sessions of strength training to build up muscle.
However, that's a choice some women who want a family make, despite the risk of recurrence. Heart disease is the leading cause of death in the United States, and women who have been diagnosed with early-stage breast cancer face a markedly increased risk of heart disease compared to the general population.
However, that's unproven at this point, he said, and would need more research.
