Objective : To present an overview of current reports and guidelines of physical activity and exercise intervention for cancer survivors Methods : We searched Pubmed for the related studies such as randomized controlled trials and observational studies, as well as published guidelines or recommendations for exercise intervention. Results : Physical activity and exercise intervention is considered safe and effective for most cancer survivors. According to the guidelines, patients with peripheral neuropathy, musculoskeletal disorder, or those who are at risk of fracture, should undergo proper medical assessment before starting exercise intervention. Also, patients with bone metastasis, thrombocytopenia, symptomatic anemia, or acute infection may fall into one of the contraindications of exercise intervention. Conclusions : Physical activity and exercise intervention may play a major role in improving physical functioning, quality of life, or treatment-related symptoms of cancer survivors. It is necessary to recognize the benefits and precautions of exercise in caring cancer patients.
