“…20,25 However, there is also evidence that physical leisure activities would already be sufficient to obtain similar results. 25 It is also important to consider that the relationship between PA and improved QOL, well-being and symptoms of fatigue in women undergoing treatment for BC is complex. The latter involves several mechanisms, such as immune, neuroendocrine changes and body composition.…”

Objective: to evaluate the relationship between levels of physical activity, fatigue and quality of life (QOL) in women diagnosed with breast cancer. Methods: 215 women between the ages of 40 and 65 years were recruited at a cancer clinic. Physical activity levels were assessed by using the International Physical Activity Questionnaire (IPAQ), fatigue levels by using the revised Piper scale, and QOL by means of EORTC QLQ-C30 and WHOQOL-Bref. Statistical analysis was performed using Minitab statistical software, version 16. Results: the mean age of subjects was 52.66 years (SD=8.6); patients were mostly white (58.14%) and overweight (55.81%). Most women were fatigued (72.09%) while physically active women showed lower symptoms of fatigue (p<0.001). Mean scores for QOL were significantly lower among fatigued women (p<0.001). More active women scored higher on all scales of QOL (EORTC), especially for functional capacity (p<0.001), compared with the sedentary patients. A significant association was found between level of physical activity and overall QOL (WHOQOL-Bref) for all domains (p<0.001). Climacteric symptoms ranged from mild to strong and did not show any statistically significant results; however, the most active women had the fewest symptoms. Conclusion: physical activity appears to positively influence fatigue and QOL in women diagnosed with breast cancer.

“…24 Several studies support the numerous benefits gained from PA, including both decreased risk of BC and decreased relapse in women diagnosed with the illness. 25 However, there is still no consensus on what intensity such exercise should be performed. Some research claims it should be from moderate to high.…”

Exercise and physical activity have been shown to reduce the risk of many common cancers and strongly influence tumor biology. A cause-effect mechanism explaining this relationship is dependent on cellular pathways that can influence tumor growth and are exercise responsive. The insulin-like growth factor (IGF) axis is reported to promote the development and progression of carcinomas through cellular signaling in cancerous tissues. This review summarizes the physiologic basis of the role of the IGF axis in oncology and the influence of exercise on this process. We examined the effects of exercise prescription on the IGF axis in cancer survivors by evaluating the current scope of the literature.The current research demonstrates a remarkable heterogeneity and inconsistency in the responses of the IGF axis to exercise in breast, prostate, and colorectal cancer survivors. Finally, this review presents an in-depth exploration of the physiologic basis and mechanistic underpinnings of the seemingly disparate relationship between exercise and the IGF axis in oncology. Although there is currently insufficient evidence to categorize the effects of exercise prescription on the IGF axis in cancer survivors, the inconsistency of results suggests a multifaceted relationship, the complexities of which are considered in this review.

“…moderate and vigorous activity (World Health Organization [WHO], 2010). Yet, breast cancer survivors who are active after treatment have a lower risk of cancer recurrence, co-morbidities and death from all causes, compared with those who are less active (Lahart et al, 2015;Gonçalves et al, 2014). As reported by Ellis, Butow, Tattersall, Dunn and Houssami (2001) and Gattellari, Voigt, Butow, & Tattersall (2002), being diagnosed with a life-threatening disease such as cancer could affect decision-making, and many patients struggle with complex and difficult treatment decisions.…”

Although scientific evidence supports the role of physical activity (PA) as a safe and effective intervention for improving health-related quality of life (for a review, see Mishra et al., 2012;Irwin, 2009), the majority of cancer survivors do not comply with public health guidelines (Blanchard, Courneya, & Stein, 2008;Lynch et al., 2010), i.e. at least 150 minutes per week of moderate-intensity aerobic PA throughout the week or at least 75 minutes of vigorous-intensity aerobic PA throughout the week, or an equivalent combination of This study was designed to demonstrate the advantage of adding cancer barriers to components of decision-making in the transtheoretical model (TTM). In study 1, questionnaires were completed by 139 breast cancer survivors including decisional balance, cancer-related barriers and stages of readiness. In study 2, efficiency of directly tackling cancer-related barriers through motivational-style conversation was tested in a quasi-experimental design. From study 1, all decisionmaking variables were related to stages of readiness, but cancer-related barriers were the sole predictors of engagement in physical activity. Out of the three groups of study 2, only the group with motivational-style conversation displayed a significant progress for engagement in physical activity. Demonstrating that cancer-related barriers predict stage of change above the effects of the two components of decisional balance provides a validation of positions that put cancer-related barriers as uniquely related to stages of change, and suggests that adding them in decision making variables in TTM's model can provide a genuinely new contribution to the understanding of physical activity adherence. Regarding implication for cancer survivors, these results suggest that in order to stimulate progress in early stages of change, a greater emphasis may be needed on reducing cancer-related barriers.

En el estudio 1 los cuestionarios fueron respondidos por 139 supervivientes de cáncer de mama, en ellos se incluyó el equilibrio decisional, las barreras relacionadas con el cáncer y las etapas de preparación. En el estudio 2 la eficacia de abordar las barreras relacionadas con el cáncer a través de conversaciones de tipo motivacional se puso a prueba con un diseño cuasi-experimental. En el estudio 1 todas las variables de toma de decisiones se relacionaron con las etapas de preparación, pero las barreras relacionadas con el cáncer fueron los únicos predictores de la participación en la actividad física. De los tres grupos del estudio 2, sólo el grupo con conversación de tipo motivacional mostró un progreso significativo para la participación en la actividad física.
