PURPOSE: To determine the effectiveness of low level laser therapy on insulin resistance and inflammatory biomarkers in obese postmenopausal breast cancer risk women BACKGROUND: The American Obesity Association (2002, 2003) defines obesity as 'a complex, multifactorial chronic disease involving environmental (social and cultural), genetic, physiologic, metabolic, behavioral, and psychological components'. However, the most commonly used definitions of obesity are based on BMI, which is defined as weight in kilograms divided by height in meters squared. In adults, obesity is generally defined as a BMI of 30.0 or greater. Obesity has become a major contributor to the global burden of chronic disease and disability. It is a complex condition with serious social and psychological dimensions, affecting virtually all ages and socioeconomic group Obesity is associated with an increased risk of developing insulin resistance and type 2 diabetes. In obese individuals, adipose tissue releases increased amounts of non-esterified fatty acids, glycerol, hormones, proinflammatory cytokines and other factors that are involved in the development of insulin resistance. In overweight and obesity, there exists low-grade chronic inflammation characterized by the increase of cytokines and serum concentrations such as fibrinogen and C-reactive protein (CRP) The areas of low - intensity laser use have expanded in several conditions by different mechanisms and ways. LLLT has been used as an important tool for the control of the inflammatory process. Its anti-inflammatory effect has been studied and its ability to induce analgesia under different conditions has also been reported. Because laser acupuncture appears to be safe, it could be considered as a complementary form of palliative care for prevention of cancer risk, especially for clinical problems for which conventional care options are limited. Investigations suggest the benefits of low-level laser therapy (LLLT) to improve noninvasive body contouring treatments, inflammation, insulin resistance and to reduce body fat.
