Although methods for controlling most cases of severe cancer pain exist. pr
obably about 50% of patients still suffer from unnecessary, poorly controll
ed pain. Cancer pain has a substantial negative effect on mood, resulting i
n anxiety, depressive feelings and even suicidal thoughts and cognitive fun
ctions are disturbed. As cancer pain often originates from skeletal metasta
ses, movements and daily activities (ADL) functions are restricted. Cancer
pain is associated by the public with progressive disease and dying and is
therefore a trigger of existential fears, for both patients and the public.
Pain treatment and education are therefore high-priority matters with effe
cts far beyond the physical suffering.
