Lifestyle during and after cancer treatment.

The aim of this overview was to examine the evidence for links between lifestyle during and after cancer treatment and quality of life, risk of treatment side-effects, rate of progression and prevention of relapse. The reviewed studies were divided into categories according to the role lifestyle plays in progression, during treatment, and in relapse prevention. The evaluated evidence was utilised to show potential lifestyle interventions to facilitate well-being and quality-of-life initiatives. There is now persuasive evidence that dietary choice and exercise can improve the physical and psychological function of patients with cancer. There is also persuasive evidence that lifestyle choice can prevent cancer or the reoccurrence of cancer in susceptible individuals, and possibly improve survival.
