Bariatric surgery linked to higher colorectal cancer risk

Bariatric surgery doubles a patient’s risk for colorectal cancer, UK researchers reported in the British Journal of Surgery. Researchers studied a cohort of 8,794 patients who underwent gastric bypass, sleeve gastrectomy or gastric banding. However, bariatric surgery was also associated with a five-fold decrease in the risk of hormone-related cancers (breast, endometrium, and prostate).  The

A study in the journal Gut found taking daily calcium supplements may increase the risk of serrated colon polyps, a precursor lesion to colon cancer. People who took calcium or calcium plus vitamin D were more likely to develop polyps from six to 10 years after the study began, but calcium from dietary sources was

Nitrates may increase colon cancer risk

A recent study suggests nitrates in drinking water were associated with a higher risk of colorectal cancer. Researchers from Aarhus University in Denmark reported in the International Journal of Cancer wrote that exposure to the highest nitrate levels raised the risk of colorectal cancer by 15%, compared with exposure to the lowest concentrations. These findings

Highly Processed Foods Tied to Higher Cancer Risk

Every 10 percent dietary increase in packaged snacks, fizzy drinks, sugary cereals and other highly processed foods boosts the risk for cancer by 12 percent, new research suggests.    In several developed countries, ultra-processed foods may make up as much as 50 percent of the daily diet, the researchers noted. This includes convenience foods, such

Bariatric surgery reduces risk for certain cancers

Bariatric surgery appears to reduce the risk for colon, breast, endometrial, pancreatic and other cancers, according to a review of medical data from 22,198 bariatric surgery patients. Overall, bariatric surgery was associated with a 40% risk reduction for 13 obesity-related cancers and a 23% reduction in risk for other cancers. See the article on Healio

Fatty liver may predict polyp risk

A fatty liver index of 30 or greater was tied to a greater risk of colorectal adenoma, and high-index patients had more adenomas and more advanced adenomas than those with a low-index, according to a study in the Diseases of the Colon & Rectum. “The high fatty liver index may be a useful predictor of

Bacteria linked to esophageal cancer

Patients with higher levels of Tannerella forsythia bacteria, which can be associated with gum disease, may have a greater risk of esophageal cancer. The increase may be as much as 21% according to a study in Cancer Research. Other bacteria, for example Streptococcus and Neisseria bacteria, were linked to decreased risk. “Our study indicates that

Fatty liver disease may increase cancer risks

NAFLD Linked to Higher Incidence Rates of Cancer Significantly associated with HCC, colon cancer in men, and breast cancer in women Nonalcoholic fatty liver disease (NAFLD) was tied to an increased risk of hepatocellular carcinoma (HCC), colorectal cancer in men, and breast cancer in women, South Korean researchers found. Adjusted results from an observational meta-analysis
