Breast Cancer is currently number one among Cancers in Women and occupy 2nd to 3rd in cause of Cancer-related deaths in Women. While various policies on prevention through education and screening have been put in place by different Governments Worldwide, the situation is still grim – Women are diagnosed of Breast Cancer and will possibly die of same within 5-10 years of diagnosis. This begs the question – what can be done to increase quantity and quality of Life of those diagnosed of Breast Cancer?
New research highlights key recommendations that breast cancer survivors can incorporate into their lifestyle so as to reduce the risk of breast cancer recurrence.
However, in some cases, the cancer does recur, either in the same form or more aggressively than the first time. Research suggests that overall, almost 30 percent of women who were diagnosed with breast cancer at an early stage develop metastasis later on.
New research examines some of the lifestyle factors that influence breast cancer recurrence rates.
The research was conducted by Dr. Ellen Warner, of the Sunnybrook Health Sciences Centre in Canada, in collaboration with coauthor Dr. Julia Hamer, and the findings were published in the Canadian Medical Association Journal (CMAJ) .
The study consists of a meta-analysis of 67 articles that examine several lifestyle choices, including exercise, weight management, dietary patterns, smoking, and alcohol consumption. The review investigates the impact of these lifestyle changes on the chances of recurring cancer and summarizes key points.
While the authors present their key findings as recommendations to patients, they also caution that the findings should not be seen as a panacea for every breast cancer survivor. Some forms of breast cancer are particularly aggressive and may come back despite the most vigorous efforts to make lifestyle changes.
“Patients should not be made to feel that inadequate lifestyle changes have led to recurrence of their cancer,” the authors note.
Of all the lifestyle factors reviewed, physical activity and avoiding weight gain seem to have the most beneficial effect on the odds of breast cancer recurrence.
The researchers comment:
“Of all lifestyle factors, physical activity has the most robust effect on breast cancer outcomes. Weight gain of more than 10 percent body weight after a breast cancer diagnosis increases breast cancer mortality and all-cause mortality. However, there are good reasons to discourage even moderate weight gain because of its negative effects on mood and body image.”
Women who are overweight or obese seem to have the lowest chances of survival. By contrast, women who exercise moderately – 30 minutes of physical activity every day, 5 days a week, or 75 weekly minutes of intense exercise – significantly reduce their risk of breast cancer recurrence and breast cancer death.
Diet, however, does not seem to have an impact on breast cancer recurrence. No specific diet was shown to reduce the risk, and the authors note soy consumption is not harmful, but quite the opposite – replacing meat protein with soy might help patients avoid weight gain.
“Making positive lifestyle changes can be psychologically beneficial to patients by empowering them, since the feeling of loss of control is one of the biggest challenges of a cancer diagnosis,” they write, adding:
“Because it is common for patients to reduce their level of physical activity after a breast cancer diagnosis, it is important for health care professionals to promote and encourage exercise in this patient population. Simply receiving advice from an oncologist to exercise more has been shown to increase patients’ level of activity.”
