From Our Blog. Data collected for each participant included age, educational level, height and weight, menopausal status, age at menarche, number of children, age at first birth, use of hormone replacement therapy HRTprevious weight loss reduce cancer risk Dietas rapidas benign breast diseases, family history of breast cancer, physical activity during the year previous to diagnosis, smoking status, and diet.

Based on highest educational level achieved, participants were classified into 3 categories: no formal education - up to first grade; primary education - vocational training; and university graduate or higher. For dietary assessment, cases and controls completed a validated semiquantitative food frequency questionnaire FFQ similar to the Harvard questionnaire Weight loss reduce cancer risk item FFQ has been adapted to and validated in different Spanish adult populations 23and covered eating habits during the preceding 5 years.

Responses were converted to mean daily intake in grams by multiplying consumption frequency by the nutrient content of the portion size specified in the FFQ. From these data we also calculated level of adherence to the Western, Prudent and Mediterranean dietary patterns. Western dietary pattern characterized by a high intake of high-fat dairy products, processed meats, refined weight loss reduce cancer risk, sweets, high-calorie drinks, convenience food, and sauces; and by low intakes of low-fat dairy products and whole grain and Mediterranean dietary pattern characterized by a high intake of fish, vegetables, legumes, boiled potatoes, fruits, olives, and vegetable oil weight loss reduce cancer risk a low intake of juices were already associated with breast cancer risk in a previous EpiGeicam study 20and therefore, possible confounders in the present study.

Subsequently, Principal Components Analysis without rotation of the variance-covariance matrix was applied. We then calculated the adherence score to Western, Prudent and Mediterranean dietary patterns as a linear combination of the weights of each food group pattern loadings in the previously mentioned study 20and the log-transformed centered food group consumption reported by the dieta del apio pepino y pinar. Due to the protective effect of physical activity on breast cancer risk previously detected in these women 21in the present study we decided to adjust for overall physical activity during the year previous to the breast cancer diagnosis in cases or during the year prior to interview in controls.

Relative caloric weight loss reduce cancer risk was our main variable of interest as a potential predictor of breast cancer risk.

Its creation consists of several steps detailed below. First, we calculated the basal metabolic rate using the predictive equations derived from meta-regression weight loss reduce cancer risk of 47 studies developed by Sabounchi et al.

Our primary aim was to evaluate the potential association between relative Adelgazar 50 kilos intake and a diagnosis of histologically confirmed invasive breast cancer.

Weight loss reduce cancer risk, the values for the main outcome variable were Case vs. Our secondary aim was similar, but exploring the link between caloric intake and the different pathologic breast cancer subtypes.

Thus, we created a second dependent variable based on tumour classification according to estrogen receptor ERprogesterone receptor PRand the human epidermal growth factor receptor 2 HER2 status according to a simplified version of the St Gallen international consensus Controls were the reference category. Our primary aim, the potential association between relative caloric intake and breast cancer risk, was assessed using conditional logistic regression models.

Linear trends were tested by entering the independent variable, relative caloric intake, as a continuous term. We adjusted for potential confounders: educational level, BMI one year prior to the interview, menopausal status these last two variables were included in the models with the corresponding interaction termsmoking status, age at first birth with a category of nulliparousage at menarche, history of benign breast disease, family history of breast cancer, HRT use, physical activity, and level of adherence to Western weight loss reduce cancer risk Mediterranean dietary patterns.

Additionally, we evaluated the potential effect modification of menopause on the predictive variable by including an interaction term between relative caloric intake and menopausal status. Our secondary aim, to test whether the perdiendo peso of interest varied across pathological subtypes, was assessed using multinomial logistic regression models with pathological subtype as the dependent weight loss reduce cancer risk.

Models were fully adjusted as described weight loss reduce cancer risk including also age and recruiting area. Heterogeneity of effects for the different cancer subtypes was tested using the Wald statistic. Finally, given the matching nature of our data, we used Multiple Imputation by Chained Equations to impute missing values for overall physical activity during the previous year 8.

Imputation models included these variables as well as the following confounding variables with complete information: case-control status, age, parity, menopausal status, educational level, caloric intake, and previous chronic diseases.

Of the case-control pairs recruited, 44 were excluded due to implausible caloric intake values at least in one of each member below or above calories. Thus, the current analyses are based on case-control participant pairs.

Compared with controls, cases weight loss reduce cancer risk lower educational level, higher proportion of postmenopausal overweight women, slightly higher age at menarche, higher frequency of previous benign breast diseases, more relatives with breast cancer, higher caloric intake and more adherence to the Western dietary pattern.

A similar trend was observed for TN tumours, although the associations failed to attain statistical significance probably due to the limited number of cases. The effect was very consistent across all strata.

Our results suggest that restricted caloric intake offers a protective effect against breast cancer, especially in premenopausal women, whereas excessive caloric consumption increases breast cancer risk.

The latter effect is observed mainly weight loss reduce cancer risk postmenopausal women and women reporting low adherence to the Mediterranean diet. A positive association between relative caloric intake and breast cancer was observed in all pathologic subtypes, though the association failed to reach statistical significance among women with TN tumours due, most likely, to a limited number of cases.

This study has several strengths. First, this is a multicenter Adelgazar 10 kilos carried out in 9 Spanish regions located throughout the second largest country in Europe.

Second, to our knowledge, this is the first epidemiological study to date that explores the effect of caloric deficit or excessive caloric consumption according to the individual energy requirements of each woman based on her basal metabolic rate and physical activity performed.

Previous studies have examined the joint effect of energy intake, physical activity, and body size; however, their analyses were stratified by those three components 14151617 weight loss reduce cancer risk, Third, because physiological pathways and metabolic effects of calories vary by source i. All the possible combinations of these two variables allowed us to capture and adjust for the broad diversity of food consumption patterns found across Spain.

Fourth, regarding breast cancer subtypes, as far as we are aware of, this is the first study exploring the association between caloric intake and breast cancer risk considering HER2 status separately. Finally, the large sample of premenopausal participants allowed for a fully adjusted exploration of the effect of caloric consumption on weight loss reduce cancer risk group. Several limitations should be considered when interpreting our findings.

First, the explanatory variables of interest are based on self-reported data, thus subject to recall bias.

Bariatric surgery has been shown to provide sustained weight loss and to decrease obesity-related mortality in most patients with morbid obesity, but its effect on cancer risk is less clear. Our aim was to review the published studies on the association between bariatric surgery and cancer risk.. A literature search for relevant articles published in English, with no limitation on the year of publication, was conducted using PubMed.

The Lancet Oncologyweight loss reduce cancer risk 8ee Lauby-Secretan, B. New England Journal of Medicine8 This finding was also supported by Adams et al. Building weight loss reduce cancer risk these results, they conducted another retrospective cohort study 9 with the purpose of testing whether reduced cancer mortality following bariatric surgery was due to decreased incidence.

Adelgazar 40 kilos study revealed weight loss reduce cancer risk lower incidence of cancer in surgery patients, although the protective effect of surgery was limited to women and to obesity-related cancers. Following this principle, McCawley et al. Along these lines, the SOS study 10 reported reduced cancer incidence in obese women but not in obese men.

A previous study 6 by the same authors had shown a reduced overall mortality weight loss reduce cancer risk with bariatric surgery, but it was no sufficiently powered to assess mortality due to specific causes.

Contrary results were obtained in a population-based cohort study by Östlund et al. To ascertain conclusively the effects of bariatric surgery on oncologic outcomes, Tee et al. Stratification by gender was also pursued, and the protective effect of bariatric surgery was only demonstrated for women. A similar conclusion was reached by Ashrafian et al. The above-mentioned studies have limited data for other endpoints than the overall cancer risk, but some differences in specific cancer risk were noted in two studies.

Different results were obtained in Östlund et al.

This unexpected finding led the authors to hypothesize that obesity surgery might be associated with increased colorectal cancer risk and they designed a nationwide retrospective cohort study, 15 which concluded that the risk for colorectal cancer increased with time after surgery. There are two weight loss reduce cancer risk articles 4,13 that weight loss reduce cancer risk discuss the potential influence of obesity surgery on some specific cancers, focusing on the upper gastrointestinal Adelgazar 72 kilos. They both concluded that it is impossible to quantify esophagogastric cancer incidence after surgery because of the paucity of data.

They also agreed that carefully evaluation of digestive tract symptoms is mandatory after bariatric surgery in order to prevent the delay in diagnosis.

Until recently, all the published articles that focused on the potential link between bariatric surgery and cancer risk had reported a protective effect, 3,5—10,14 but the current controversy arose with the publication of the article by Derogar et al.

This study has had a significant impact on the bariatric surgery community, becoming an important matter of debate. Our task is to make weight loss reduce cancer risk about the strength of the evidence and the validity of the data before reaching any conclusion.

In the first studies to appear on this topic, 3,5,6 the primary outcome was designated as mortality or morbidity from any cause, not specifically from cancer.

Although the results revealed a lower incidence of cancer in the surgery cohort, the probability of a chance effect was increased, since multiple statistical comparisons were performed. Therefore, those studies were only powered and monitored on the basis of the primary outcome variable.

Regarding the studies in which cancer risk constitutes the primary outcome, 7—11 no randomized trials have been conducted yet. Thus, the main limitations include their designs, which do not achieve the highest levels of evidence. Even though it could not be randomized for ethical reasons, SOS study 10 provides the best evidence with a robust matching of the surgery group, taking into account a richness of cardiovascular, anthropometric and biochemical parameters.

This prospective cohort study included ten pre-defined visits in both surgery and control groups, so the chance for cancer detection was similar in both groups. They stated a reduced cancer incidence in obese weight loss reduce cancer risk but not in men after a follow-up of 15 years, which persisted after the exclusion of all cancer cases that appeared during the first 3 years of intervention.

However, secondary subgroup analysis showed no associations between cancer incidence and weight loss or reduced energy intake, which could have been explained by limited statistical power as a consequence of dividing into multiple subgroups. But another explanation could be the interesting possibility that the beneficial effects of bariatric surgery on cancer could be explained by mechanisms other than reduced energy intake or weight loss.

Actually, several mechanisms have been proposed to explain the weight loss reduce cancer risk cancer protective role of bariatric surgery, like the improvement of insulin resistance, decreased oxidative stress Adelgazar 10 kilos inflammation, along with the beneficial modulation of sex-steroids, gut hormones, cellular energetics, adipokines and the immune system, 12 but more investigation needs to be done in this field to clarify the precise metabolic mechanisms.

As we acknowledged, the majority of the studies state that bariatric surgery might have a protective role in cancer risk, although its effect seems limited to women, reinforcing the importance of studying mechanisms separately by gender. Focusing in obese women, breast and endometrial cancers weight loss reduce cancer risk the most common types, which are hormonally responsive tumors.

As it is known, obesity results in a profound change weight loss reduce cancer risk hormone levels, with effects on circulating peptide and steroid hormones and their binding factors, and these changes may be partially corrected with weight loss. Taking this into account, the control group used by Östlund et al. Subsequently, not weight loss reduce cancer risk done a carefully control group selection may lead into some misunderstanding and this could be one of the reasons why the observed cancer risk in the surgery cohort was not decreased.

Indeed, Tee et al. However, standardizing in order to have homogeneous groups does not exclude the influence of other factors La buena dieta the existence of some biases, for example, operative candidates may have been more motivated to quit smoking, weight loss reduce cancer risk more exercise or follow healthy diets, which could have influenced the results of the studies that showed a decreased risk.

Weight loss reduce cancer risk the same way, focusing on the controversial study 15 that detected an increased risk of colorectal cancer, factors like weight change, body mass distribution are known to influence its incidence, along with the type of diet or the use of protective drugs like aspirin. Regarding this last study, 15 there are some other considerations that should be taken into account.

Conventionally, bariatric surgery has been subdivided into restrictive procedures and malabsorptive procedures, and this study, which included both techniques, found that the increased weight loss reduce cancer risk was similar for all the techniques. Some authors 16 point out that it is hard to understand how cancer risk could be increased when restrictive procedures were performed since the anatomical or absorptive function of the gastrointestinal tract remained untouched.

However, rectal mucosal hyperproliferation persists at least 3 years after Roux-en-Y gastric bypass, which has been associated with increased mucosal expression of the protumorigenic cytokine macrophage migration inhibitory factor, 17 and recent studies weight loss reduce cancer risk also stated alterations in the intestinal microbiota and an increased mucosal bile salt exposure, 18 both implicated in long-term neoplastic risk.

Moreover, the effect of postsurgical neurohormonal modulation may also play a role. In this sense, controversial findings about ghrelin levels in different stages of colon cancer cause to raise the question whether it is carcinogenic or protective against gastrointestinal malignancies.

In fact, the same authors have initiated a Nordic study and a separated British population study in order weight loss reduce cancer risk confirm their findings, 21 using independent databases.

The so-called toxic triad of factors linked to cancer, namely obesity, poor cardiorespiratory fitness CRF and physical inactivity, increase the risk of cancer and, when cancer is present, worsen its prognosis. Thus, obesity and a sedentary lifestyle have been linked to an elevated cancer risk whereas regular physical exercise and good CRF diminish this risk. Despite genetic risk factors, there is evidence to show that some lifestyle modifications are capable of reducing the incidence of cancer and its associated morbidity and mortality. Regular physical exercise targeted at maintaining body weight within healthy limits and improving CRF will reduce a person's cancer risk and, once diagnosed, will also improve its prognosis, reducing mortality and the risk of disease recurrence through similar effects. In this review, we describe how physical activity can be used as a pleiotropic, coadjuvant tool to minimize the toxic triad for cancer and update the mechanisms proposed to date for the effects observed.
