#Nut Consumption and Risk of #Cancer: A Meta-analysis of Prospective Studies

..When comparing the highest with the lowest category of nut intake, high consumption of nuts was significantly associated with decreased risk of overall cancer (RR = 0.90; 95% CI, 0.85–0.95). The protective effect of nut consumption was especially apparent against cancers from the digestive system (RR = 0.83; 95% CI, 0.77–0.89). Among different nut classes, significant association was only obtained for intake of tree nuts. … Continue reading #Nut Consumption and Risk of #Cancer: A Meta-analysis of Prospective Studies

#Curcumin and #Cancer

Curcumin, a polyphenol extracted from Curcuma longa in 1815, has gained attention from scientists worldwide for its biological activities (e.g., antioxidant, anti-inflammatory, antimicrobial, antiviral), among which its anticancer potential has been the most described and still remains under investigation. The present review focuses on the cell signaling pathways involved in cancer development and proliferation, and which are targeted by curcumin. Curcumin has been reported to … Continue reading #Curcumin and #Cancer

Electronic-#cigarette smoke induces #lung adenocarcinoma and #bladder urothelial hyperplasia in mice

Electronic-cigarettes (E-cigs) are marketed as a safe alternative to tobacco to deliver the stimulant nicotine, and their use is gaining in popularity, particularly among the younger population. We recently showed that mice exposed to short-term (12 wk) E-cig smoke (ECS) sustained extensive DNA damage in lungs, heart, and bladder mucosa and diminished DNA repair in lungs.. ..We found that mice exposed to ECS for 54 … Continue reading Electronic-#cigarette smoke induces #lung adenocarcinoma and #bladder urothelial hyperplasia in mice

Prevalence and clinical implications of #sarcopenic obesity in patients with solid tumours of the respiratory and gastrointestinal tracts: a population-based study

Emerging evidence on body composition suggests that sarcopenic obesity (obesity with depleted muscle mass) might be predictive of morbidity and mortality in non-malignant disease and also of toxicity to chemotherapy.. ..Available lumbar CT images of the obese patients were analysed for total skeletal muscle cross-sectional area; these values were also used to estimate total body fat-free mass (FFM).. ..Sarcopenic obesity was associated with poorer functional … Continue reading Prevalence and clinical implications of #sarcopenic obesity in patients with solid tumours of the respiratory and gastrointestinal tracts: a population-based study

Healthy #lifestyle and life #expectancy free of cancer, cardiovascular disease, and type 2 diabetes: prospective cohort study

..Five low risk lifestyle factors: never smoking, body mass index 18.5-24.9, moderate to vigorous physical activity (≥30 minutes/day), moderate alcohol intake (women: 5-15 g/day; men 5-30 g/day), and a higher diet quality score (upper 40%). .. The life expectancy free of diabetes, cardiovascular diseases, and cancer at age 50 was 23.7 years (95% confidence interval 22.6 to 24.7) for women who adopted no low risk … Continue reading Healthy #lifestyle and life #expectancy free of cancer, cardiovascular disease, and type 2 diabetes: prospective cohort study

Amount and Intensity of Leisure-Time #Physical Activity and Lower #Cancer Risk

To determine whether recommended amounts of leisure-time physical activity (ie, 7.5-15 metabolic equivalent task [MET] hours/week) are associated with lower cancer risk.. ..Engagement in recommended amounts of activity (7.5-15 MET hours/week) was associated with a statistically significant lower risk of 7 of the 15 cancer types studied, including colon (8%-14% lower risk in men), breast (6%-10% lower risk), endometrial (10%-18% lower risk), kidney (11%-17% lower … Continue reading Amount and Intensity of Leisure-Time #Physical Activity and Lower #Cancer Risk

A Review of the In Vivo Evidence Investigating the Role of #Nitrite Exposure from Processed Meat Consumption in the Development of Colorectal #cancer

..The World Cancer Research Fund (WCRF) 2007 stated that the consumption of processed meat is a convincing cause of colorectal cancer (CRC), and therefore, the public should avoid it entirely. Sodium nitrite has emerged as a putative candidate responsible for the CRC-inducing effects of processed meats. Sodium nitrite is purported to prevent the growth of Clostridium botulinum and other food-spoiling bacteria, but recent, contradictory peer-reviewed … Continue reading A Review of the In Vivo Evidence Investigating the Role of #Nitrite Exposure from Processed Meat Consumption in the Development of Colorectal #cancer

Sustained #weight loss and risk of #breast cancer in women ≥50 years: a pooled analysis of prospective data

..Compared with women with stable weight (± 2kg), women with sustained weight loss had a lower risk of breast cancer. This risk reduction was linear and specific to women not using postmenopausal hormones (>2-4.5kg lost: Hazard Ratio (HR)= 0.82, 95% confidence interval (CI): 0.70-0.96; >4.5-<9kg lost: HR = 0.75, 95% CI: 0.63-0.90; ≥9kg lost: HR = 0.68, 95% CI: 0.50-0.93). Women who lost ≥9kg and gained some (but not … Continue reading Sustained #weight loss and risk of #breast cancer in women ≥50 years: a pooled analysis of prospective data

Association of Indoor #Tanning Exposure With Age at #Melanoma Diagnosis and BRAF V600E Mutations

..The 114 patients who reported indoor tanning exposure were younger at diagnosis than the 222 patients who did not (51.5 vs 64.0 years, two-sided P < .001). BRAF V600E genotype was more prevalent in ever-users than in nonusers (42.9% vs 28.3%, two-sided P = .04) and higher in ever-users who initiated indoor tanning prior to age 25 years compared with age 25 years or older (62.2% vs … Continue reading Association of Indoor #Tanning Exposure With Age at #Melanoma Diagnosis and BRAF V600E Mutations

Use of #anastrozole for #breast cancer prevention (IBIS-II): long-term results of a randomised controlled trial

..3864 women were recruited between Feb 2, 2003, and Jan 31, 2012. 1920 women were randomly assigned to 5 years anastrozole and 1944 to placebo. After a median follow-up of 131 months (IQR 105–156), a 49% reduction in breast cancer was observed for anastrozole (85 vs 165 cases, hazard ratio [HR] 0·51, 95% CI 0·39–0·66, p<0·0001). The reduction was larger in the first 5 years … Continue reading Use of #anastrozole for #breast cancer prevention (IBIS-II): long-term results of a randomised controlled trial

Association Between #Marijuana Use and Risk of #Cancer A Systematic Review and Meta-analysis

.. In pooled analysis of case-control studies, ever use of marijuana was not associated with head and neck squamous cell carcinoma or oral cancer. In pooled analysis of 3 case-control studies, more than 10 years of marijuana use (joint-years not reported) was associated with TGCT (OR, 1.36; 95% CI, 1.03-1.81; P = .03; I2 = 0%) and nonseminoma TGCT (OR, 1.85; 95% CI, 1.10-3.11; P = .04; I2 = 0%).
