"This type of breast cancer usually has a worse prognosis than other types".
The study was led by professor of Maastricht University in the Netherlands, Piet van den Brandt. However, Dr. Fang Zhang, the research director, cautioned that other studies suggest that the estrogen-like effects of isoflavones may decrease the effectiveness of hormone therapies used in the treatment of breast cancer.
To provide some clarity, researchers looked at the relationship between dietary intake of isoflavones and death from any cause in 6235 American and Canadian women diagnosed with breast cancer.
Although the traditional Mediterranean Diet involves moderate consumption of alcohol, in this study alcohol was excluded from the criteria, as this is a known risk factor for breast cancer, and linked to 12,000 cases annually.
The latest study, based on 62,573 women aged between 55 and 69, found that those who stuck to a Mediterranean diet most closely could significantly reduce their risk of developing the oestrogen-receptor negative (ER-negative) subtype of breast cancer.
Now, a study has said that women following the Mediterranean diet, which is rich in fresh fruits, vegetables, lean proteins and healthy fats and low in refined sugars and saturated fats, are 40 percent less likely to develop ER-negative breast cancer.
Previous findings have shown that nearly 12,000 cases of breast cancer could be prevented in the United Kingdom each year if alcohol consumption ceased.More news: Woman questioned after 9yo boy mauled, 5yo boy missing in Murray River
The same analysis was conducted based on early adulthood diet, and researchers determined that those in the highest inflammatory score group had a 41% higher risk for premenopausal breast cancer relative to those in the lowest-score group.
The researchers say the benefits of a Mediterranean diet on reducing the risk of cancer may be explained by its high amounts of fibre, antioxidants and vitamins and its ability to reduce inflammation and oxidative stress.
During this time, there were 3,354 breast cancer cases among those taking part. About 40 per cent of all cancers are linked to lifestyle and the risk of breast cancer is heightened by obesity, poor diet, alcohol and smoking.
But the study found the Mediterranean diet only had a weak and non-significant effect on the risk of developing hormone-sensitive breast cancer.
"Breast cancer isn't just one disease - not all types have the same triggers and this study unpicks these complexities".
"However, it's important to remember while lifestyle choices help reduce the risk of cancer, they don't guarantee prevention".
"So it's crucial women know the signs and symptoms of breast cancer, and contact their GP with any concerns".
