Melanoma is so dangerous because it tends to metastasize early on. New treatment approaches utilize, among other things, the ability of the immune defense to search out and destroy malignant cells. Yet this strategy is often only temporarily effective. A research team has discovered why this is the case: In the inflammatory reaction caused by the treatment, the tumor cells temporarily alter their external characteristics and thus become invisible to defense cells. This knowledge forms an important foundation for the improvement of combination therapies.
