An increasing number of individuals diagnosed with cancer survive and die of a new cancer or other lifestyle-related diseases. With the intent to encourage and assist oncologists in promoting lifestyle changes to improve health of their patients, this article sums up the evidence behind a brochure including ten one-line health messages in Danish inspired by the American initiative Cancer Survivors' Eight Ways to Stay Healthy After Cancer. We conclude by discussing the challenges of implementation of preventive and health promoting activities in clinical practice in Denmark.
