Women who take vitamin D after being diagnosed with breast cancer have a greater chance of survival, according to a new study supported by the Irish Cancer Society.
Researchers at the Irish Cancer Society's cancer research center, BREAST-PREDICT, analyzed data from nearly 5,500 breast cancer patients and found an increase in relative survival of 20% over other. The study was conducted by cancer researchers based at RCSI (Royal College of Surgeons in Ireland).
Miriam O'Callaghan, a breast cancer researcher, has launched "Cups Against Breast Cancer", a fundraising campaign of the Irish Cancer Society to raise funds for breast cancer research and cancer services. support.
Breast cancer is the second most common cancer in women, and at Meath, 95 women were diagnosed with breast cancer over a 12-month period.
Dr. Robert O'Connor, Director of Research at the Irish Cancer Society, said: "This research is an example of the BREAST-PREDICT program, made possible by the country's support for fundraising campaigns such as" Cups Against Breast Cancer.
"Since the Irish Cancer Society created BREAST-PREDICT five years ago, we have funded the work of more than 50 breast cancer researchers across the country. This means an investment of 7.5 million euros that was only possible thanks to generous donations from the public.
"The Irish Cancer Society can only invest in cancer research with this support. Throughout the month of October, we are asking the people of Meath to continue this support by holding a coffee morning for the Breast Cancer Cup to raise funds for breast cancer research and services. free patient support.

This research was led by Dr. Jamie Madden, a researcher at RCSI, under the supervision of Prof. Kathleen Bennett, Associate Professor of Pharmacoepidemiology at Dublin RCSI. For research, the National Cancer Registry of Ireland provided anonymized data on pharmacy requests from nearly 5,500 women with breast cancer aged 50 to 80 between 2000 and 2011.
Professor Bennett said, "Previous studies have shown that high blood levels of vitamin D, which can come from our diet, sunlight or supplements, are associated with an increase in breast cancer survival. Our study suggests that vitamin D supplementation might be helpful for women with breast cancer. Major clinical trials are already under way abroad to further this question.
The results of the research team were recently published in the journal "Research and Treatment of Breast Cancer".
Although the results are significant, the researchers did not have access to information on other measures of women that may have an impact on their likelihood of better outcomes. For example, more and more studies show that moderate physical activity and maintaining a healthy diet may be beneficial for a patient undergoing cancer treatment, but this study did not determine .
Research has also shown that vitamin D users are on average younger, less likely to smoke, and have a lower tumor stage and tumor progression than non-users, all of which are more likely to contribute to better outcomes. survival.
Dr. O'Connor added, "Before purchasing vitamin D supplements, we urge women with breast cancer to consult their medical team. Vitamin D consumption can lead to health problems and each woman's cancer is unique and will require personalized treatment.
"Although this is an important preliminary study, the results show only a link of association, not of causality. We will only know if vitamin D supplementation should be recommended to improve the results of breast cancer treatment in the coming years when the results of clinical trials are known. "
