Cancer survivor Jan Geissler, who lives in Germany, is an active patient advocate globally. In this interview, he shares the reasons he became an advocate and steps he feels others can take to have a voice in their own health care. He also talks about actions being taken in Europe and the progress being made there in giving more patients input into the clinical trial process. Geissler, a chronic myelogenous leukemia (CML) patient, points out the success made in developing new treatments for CML patients and the benefits that knowledge is providing for many other types of cancers. He says great progress has been made, but there is still much more to be done. He advises patients to become informed, join patient support groups and to seek second medical opinions when they feel they are needed.
