It was only in the past few decades that research found diet plays a role in preventing colon cancer. Now, a study suggests that colon cancer patients whose diets are relatively low in starchy foods and carbohydrates have a lower risk of recurrence and death compared to those eating a high carb diet.
The findings were published online yesterday in the Journal of the National Cancer Institute.
The study builds on the authors’ earlier research that observed a link between an overall pattern of eating and recurrence among colon cancer patients. That study found patients who ate the most fats, meats, carbs and sugary desserts — a Western diet — were three times more likely to have their cancer recur compared to those whose diets were least Western.
The current study focused on teasing apart which part of the Western diet might most contribute to the effect. 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
I’ve been listening to a lot of research about exercise here at the American College of Sports Medicine conference and for cancer survivors, the evidence is heartening: activity may help survivors’ health.
One of the latest major published studies mentioned here links physical activity to a longer life among breast and colon cancer patients. Exercise may also lengthen the life of other cancer survivors, but the evidence for that is not as clear, the study concluded.
The analysis comes ahead of the 25th annual National Cancer Survivors Day, which is this Sunday. It was published in the Journal of the National Cancer Institute.
The authors looked at all relevant studies published from 1950 to 2011, ending up with a total of 45 articles. The studies focused on physical activity, and cancer survival and/or biological indicators – biomarkers – of survival. Continue reading
