The clinical effects of physical activity in cancer survivor

Introduction: A cancer survivor is defined as anyone who has been diagnosed with cancer, from the time of diagnosis through the rest of their life.Many cancer survivors are highly motivated to seek information about food choices, physical activity, and complementary nutritional therapies to improve their response to treatment, speed recovery, reduce their risk of recurrence, and improve their quality of life(1).The short-term (the rehabilitation period immediately follows primary treatment) and long-term(the prevention/health promotion period) benefits of exercise after cancer treatment have been considered. The aim of this study to evaluate the scientific evidence and best clinical practices related to physical activity and the diagnosis of cancer. Methodology: We planned to assess the effects of physical activity on cancer outcomes (that is, rates of survival and recurrence), psychological outcomes, and physical outcomes. A systematic search of medical Literature from the MEDLINE and PubMed database published (from 2007 to August 2015) using the search terms physical activity OR execise AND Diet OR Nutrition AND cancer AND clinical Trials were done. We also reviewed the reference lists of articles to identify relevant studies. The inclusion criteria followed the PIOC (Population, Intervention, Outcomes, and Comparison) framework.The population under study was defined as: cancer patients who had recently completed adjuvant chemotherapy and/or radiotherapy Results: The beneficial impact of Physical Activity Issues by Selected Cancer Sites was also studied, for example postdiagnosis physical activity was associated with a lower rate of breast cancer recurrence and mortality. The result of the Colon Health and Life-Long Exercise Change (CHALLENGE) trial indicates that Colorectal cancer survivors should be advised to maintain a healthy weight, participate in regular physical activity for cancer and heart disease prevention. The other substantial benefits of physical activity which has been seen in Endometrial Cancer and Ovarian Cancer, Hematologic Cancers and Cancers Treated With Hematopoietic Stem Cell Transplantation, Prostate Cancer, Upper Gastrointestinal , Head and Neck Cancers, are a lower risk of disease recurrence and improved survival, decreased cardiovascular disease and obesity risk. Impact of Obesity on cancer Treatment, can influence the accuracy of cancer diagnostics such as certain surgical complications, higher rates of toxicity and reduced imaging quality. Discussion: Exercise is an important treatment for the recovery and rehabilitation of cancer survivors(2). A combination of yoga with aerobic exercise and resistance training should be considered to maximize the physiological, functional and anthropometric benefit for cancer survivors. The American College of Sports Medicine (ACSM) panel recommended that individuals avoid inactivity and return to normal activity as soon as possible after diagnosis or treatment. The principal goal for cancer patient should be encouraged to adopt a physically active lifestyle, rather than none. References: 1.
