Recently, the Portuguese press announced in several front pages that a private Foundation (Fundação Champalimaud) was capable to cure 90% of cancer patients with single dose radiotherapy. This announcement was very unfortunate. It is obviously a false statement from the professionals and scientists standpoint, but not for patients. Patients and their families tend to invest their expectations in whatever promise, even if the “good news” may sound as suspicious to everybody that is not sufficiently acquainted with science progress (and limitations).
