The American Cancer Society (ACS) released new guidelines today, with advice especially aimed at cancer survivors seeking help about avoiding the return of the disease, or hoping to protect family members from their own plight. The ACS recommendations are pretty straight forward, although many of us find it hard to implement and maintain them. Volumes of research has shown that physically active, non smokers, who maintain a healthy lifestyle and eat a diet of more fruits, vegetables and grains, are far less likely to suffer from cancer than those with less healthy lifestyles. Alcohol consumption is also red flagged. Those following their recommendations also benefit from decreased risk of cardiovascular disease. Whilst in theory the same advice should apply to cancer survivors, there was little hard data on the matter, but recent research has made the picture much clearer.
Protection Against Many Cancers Provided By Vitamin E In Diet But Not The Form Commonly Used In Supplements
Next time you need to choose between vegetable oil and margarine in that favorite recipe, think about your health and reach for the oil. While the question of whether vitamin E prevents or promotes cancer has been widely debated in scientific journals and in the news media, scientists at the Center for Cancer Prevention Research, at Rutgers Ernest Mario School of Pharmacy, and the Cancer Institute of New Jersey, believe that two forms of vitamin E - gamma and delta-tocopherols - found in soybean, canola and corn oils as well as nuts do prevent colon, lung, breast and prostate cancers. "There are studies suggesting that vitamin E actually increases the risk of cancer and decreases bone density, " says Chung S. Yang, director of the center. "Our message is that the vitamin E form of gamma-tocopherols, the most abundant form of vitamin E in the American diet, and delta-tocopherols, also found in vegetable oils, are beneficial in preventing cancers while the form of vitamin E, alpha- tocopherol, the most commonly used in vitamin E supplements, has no such benefit.
The Anticancer Effects That Come With Breastfeeding May Be Due To High Levels Of TRAIL Protein In Breast Milk
The benefits of breast milk are well known, but why breastfeeding protects against various forms of cancer remains a mystery. A new study in the Journal of Human Lactation (published by SAGE) found high levels of cancer-fighting TNF-related apoptosis inducing ligand (TRAIL) in human milk, which might be one source of breast milk's anticancer activity. Researchers took samples of colostrum, the first milk available to newborns, and of mature breast milk from new mothers. Researchers then obtained samples of blood from healthy women, and various ready-to-feed infant formulas. The colostrum, mature breast milk, blood and formula were then all tested to measure their level of TRAIL. The researchers found that colostrum and breast milk contained 400- and 100-fold, respectively, higher levels of TRAIL than blood.
Colon cancer patients who take aspirin regularly shortly after diagnosis tend to live for longer, researchers from Leiden University Medical Centre, the Netherlands, reported in the British Journal of Cancer. The authors explain that NSAIDs (non-steroid anti-inflammatory drugs) have been known to have a preventive role with regards to colorectal cancer, and in particular, aspirin. Recently, some studies and experts have suggested that regular aspirin may have a therapeutic role too. However, studies so far have not been conclusive. Dr Gerrit-Jan Liefers and team set out to determine what the therapeutic effect of aspirin/NSAIDs as adjuvant treatment might be on colorectal cancer patients after diagnosis. They carried out an observational population-based study. They gathered prescription data from the PHARMA linkage systems, focusing on patients who had been diagnosed with colorectal cancer (1998-2007).
Following the discovery in a new study that mice have a higher risk of developing cancer after eating the popular British-made low-calorie artificial sweetener sucralose, a leading cancer scientist calls for urgent research. Dr. Morando Soffritti, director of the Ramazzini Institute in Bologna, Italy will present the findings of the study for the first time at the Childhood Cancer 2012 conference in London. Hundreds of millions of people all around the world consume artificial sweeteners, which can be found in a large variety of foods and drinks, including soft drinks, cakes and foods for diabetics, as well as medicines. The increasing problem of obesity in developed countries, which started in the 70's in Europe and the U.S., has led to increasing demands for reduced-calorie foods and drinks.
