[Pain in adolescents with cancer.].

Adolescence is a transitional period between childhood and adulthood that can be difficult to cross. The disease is often lived as supplementary suffering, as the word cancer is often linked to a long, painful and lethal disease. The teenager presenting cancer has several obstacles to overcome: his adolescence, his cancer disease and his pain. Pain can be present throughout the cancerous disease: at diagnosis, in case of relapse, or in the event of terminal tumor progression. Pain can be difficult to assess in adolescents who are opposed to treatments or to healthcare. Pain management must be discussed with a multidisciplinary team and has to have a holistic approach including drug therapy and complementary approaches.
