Last month more than 150 people visited the Museum of Science for a series of lectures and discussions — many led by MGH staff — that provided information about cancer and its effect on patients and their families. Co-sponsored by the MGH, the Whitehead Institute for Biomedical Research, the American Society of Law, Ethics and Medicine and the Museum of Science, the two-day symposium, entitled Demystifying Cancer, also highlighted information resources about cancer treatments and research. Using the Internet as a resource was an important focus for many of the attendees.
