Dairy foods like ice cream, regular cheese and whole milk are high in fat and saturated fat, linked to an increased risk for heart disease. There is little evidence that total dietary fat affects cancer risk, but it is less clear whether specific high fat foods or types of fats affect cancer risk.
Now, a new study published in the Journal of the National Cancer Institute suggests that, for breast cancer survivors, consuming high fat dairy foods may be related to an increased risk of breast cancer mortality.
The researchers followed 1893 women diagnosed with early-stage invasive breast cancer who were enrolled in the Life After Cancer Epidemiology (LACE) study. The participants completed food frequency questionnaires, including how much dairy they consumed, when they entered the study and in 6 year follow-up surveys. In this study median follow-up was 11.8 years. Continue reading
Sweet potatoes, tomatoes, and the many other colorful fruits and vegetables high in carotenoids may reduce women’s risk of breast cancer, suggests a new analysis published last week.
The study was published in the Journal of the National Cancer Institute.
Carotenoids are a large group of phytochemicals that give our foods their red, orange, and yellow hues. Many dark green vegetables, such as kale and spinach, also contain plenty of these phytochemicals. Beta-carotene, lycopene, zeaxanthin and lutein are a handful of the well-studied carotenoids for their role in cancer prevention – and other health benefits, such as eye health. Continue reading
Research is clear that obesity increases the risk of developing breast cancer. Now, a large study suggests that women who are overweight or obese when they are diagnosed with the most common form of breast cancer have the greatest risk of an earlier death and recurrence, even when undergoing optimal treatment.
The study was published early online in the journal CANCER. Here’s the abstract.
The link was seen among women who had hormone-receptor positive breast cancer, which make up about two-thirds of breast cancers.
In all, the study included almost 7,000 women who went through treatment. The researchers pulled data from three National Cancer Institute trials that were studying the effects of chemotherapy, tamoxifen and/or other treatments on women with breast cancer. Their breast cancers ranged from the early stage to the later stage III, where the cancer could have spread to nearby lymph nodes.
The largest of the three trials tracked the women’s health for an average of 8 years; the other two followed the women for 14 years. Continue reading
