Processed Meat Increases Stomach Cancer Risk
bacon and sausageA new review has found that increasing the consumption of processed meats dramatically increases the risk for stomach cancer. The meta-analysis published in the Journal of the National Cancer Institute reviewed the evidence from studies conducted between January 1966 and March 2006 on processed meat consumption and stomach cancer risk. The review found that increasing consumption of processed meats–like bacon, ham, and sausage–by just 1-ounce daily increased stomach cancer risk by 15 percent to 38 percent. One ounce of processed meat is equivalent to approximately two strips of bacon or one small slice of deli ham. Stomach cancer is the second leading cause of cancer death worldwide and claims about 700,000 lives annually.

Adult Weight Gain Increases Risk for All Types of Breast Cancer
More evidence shows that being overweight increases a woman’s risk for breast cancer. The relationship between weight gain and a type of invasive breast cancer among 44,161 postmenopausal women was examined by a group of scientists at the American Cancer Society. Women with over 60 pounds of adult weight gain were nearly two times as likely as women with 20 pounds or less of adult weight gain to develop one form of breast cancer. Weight gain was associated with increased risk for all types, stages, and grades of breast cancer, particularly advanced cases. Obese women were three times as likely to develop regional or distant metastases compared with women who had minimal weight gain in adulthood. This study emphasizes the importance of maintaining a healthy weight throughout life.

Lifestyle Changes More Likely with Education After Breast Cancer Diagnosis
cancer educationResearchers in Providence, R.I., sought to determine why some breast cancer patients change their diets and lifestyles after diagnosis while others do not. Many breast cancer survivors eat fewer than five servings of fruits and vegetables daily, consume too much fat, and lead sedentary lifestyles. This study found that cancer survivors who believed their cancer was caused by poor diet, lack of exercise, or alcohol consumption—or who believed a diet change would help ward off recurrence—were more likely to change these behaviors. Reducing fat intake, increasing fiber intake, consuming plenty of vegetables, exercising, and maintaining a healthy weight are all believed to increase breast cancer survival. Educating breast cancer survivors on these important factors will increase their likelihood of making positive lifestyle changes.
