In March 2018 researchers from Germany, Italy, Spain, UK, The Netherlands, Austria and Turkey published their review of the medical scientific literature to assess the the impact of smoking, sexual activity, and sports and exercise on prostate cancer risk and outcome after treatment. Results showed that smoking is associated with aggressive tumour features and worse cancer-related outcome, which seems to be maintained for 10 yr after smoking cessation. In addition, physical activity appears to reduce prostate cancer risk and improve cancer-related outcomes. Less convincing and limited evidence exists for the association of sexual activity with prostate cancer risk and further research is required to assess whether the suggested association between prostate cancer risk and sexual behaviour is real or false.
