"When assessing cancer risk, body mass index (BMI) and fat percentage may not be adequate measures as they fail to assess the distribution of fat mass," she explained. "Avoiding central obesity may confer the best protection."
Obesity has become one of the leading preventable causes of cancer. Yet, the mechanisms of how obesity and associated systemic inflammation can promote cancer progression remain poorly understood. In a new study, researchers found that the cytokines interleukin 5 (IL-5) and granulocyte macrophage colony-stimulating factor (GM-CSF) are induced in obesity and, in obese mice, this leads to lung neutrophilia and supports breast cancer metastasis to the lung. Quail, Olson et al. used mouse models of obesity, induced by a high-fat diet (diet-induced obesity, DIO mice) or leptin deficiency (ob/ ob mice), to study how inflammation in obesity is linked to breast cancer metastasis.
Research is still lacking to support a link between obesity and an increased risk of developing all types of cancer. Nevertheless, a review1 of more than 1,000 epidemiologic studies by the International Agency for Research on Cancer (IARC), a division of the World Health Organization, examining the preventive effects of weight control on cancer risk […]
The ASCO Annual Meeting brings together more than 30,000 oncology professionals from around the world to discuss state-of-the-art treatment modalities, new therapies, and ongoing controversies in the field.
Type 2 diabetes mellitus (T2DM) is becoming increasingly prevalent worldwide. Epidemiologic data suggest that T2DM is associated with an increased incidence and mortality from many cancers. The purpose of this review is to discuss the links between diabetes and cancer, the effects of various antidiabetic medications on cancer incidence and mortality, and the effects of anticancer therapies on diabetes.
There is growing evidence that inflammation is a central and reversible mechanism through which obesity promotes cancer risk and progression.
The association of obesity with cancer, increasingly recognized in both lay and medical communities and underscored by the ongoing obesity epidemic, has stimulated a large body of research and led to calls for programs to minimize any potential impact of obesity on cancer
We reviewed the literature regarding overweight and obesity and breast cancer survival outcomes, overall and with regard to breast cancer subtypes, breast cancer therapies, biologic mechanisms, and possible interventions.
Observational studies have reported a modest association between obesity and risk of ovarian cancer; however, whether it is also associated with survival and whether this association varies for the different histologic subtypes are not clear. We undertook an international collaborative analysis to assess the association between body mass index (BMI), assessed shortly before diagnosis, progression-free survival (PFS), ovarian cancer-specific survival and overall survival (OS) among women with invasive ovarian cancer.
Although several studies have established a link between obesity and colon cancer risk, little is known about the effect of obesity on outcomes after diagnosis. We investigated the association of body mass index (BMI) with outcomes after colon cancer in patients from cooperative group clinical trials.
