[Contribution of physical rehabilitation to cancer follow-up].

The number of people with cancer is constantly increasing. Thanks to new screening techniques and treatment protocols, the number of survivors is also increasing. However, treatments cause some undesirable side effects that usually persist over time. The level of physical activity of these patients tends to decrease with the diagnosis of cancer and does not usually increase before the end of the treatments or even beyond. However, physical activity is beneficial not only in terms of preventing the progression or recurrence of the disease but also in the fight against side effects related to the disease and its treatments. There are various physical activity recommendations for cancer survivors that will be developed in this article. The project «Sport après cancer. Citoyen sportif, j'agis pour ma santé», developed by the University and the University Hospital of Liège, aims to promote adapted physical activity after cancer, creating a link between outpatient rehabilitation in a hospital setting and the practice of physical activity in a sporting and associative context.
