Good evening. Tonight our lead story comes from the world of medicine. Its about cancer, and its about changing how we refer to it, changing our definition of it. In part, its about the minor stuff, the comparatively smaller things that are discovered during screenings, giving them different names, making them a lot less scary. A panel of this nations top doctors now says even the word cancer is often misused. They warn not all cancers are alike, not all are deadly so they shouldnt be treated or talked about the same way. In plain english, they want to stop wasting time, money and worry and concentrate on whats important. Its where we begin here tonight with our medical editor dr. Nancy snyderman. This is important stuff. It is, good evening, brian. For many in the cancer world todays step is long overdue in making the diagnosis and treatment of cancer smarter and more cost effective. Turn the page of any dictionary, land on the letter c and find one of the most frightening words no one wants to hear, cancer. This one word carries a loaded and complex meaning for millions of americans every year. A panel of experts advising the National Cancer institute is recommending an about face in the way doctors diagnose and treat some types of the disease that have little or no chance of being lethal. In fact, the group is even taking a closer look at what the word cancer means in some instances. For example, in women the diagnosis ductal carcinoma in situ is a nonlethal breast disease that should not be called cancer. Whenever something is called carcinoma or cancer, people immediately want to act, and the reality is we should be watching them as opposed to aggressively treating. 66yearold rue harris wishes he had taken a conservative approach to a possible Prostate Cancer diagnosis a few years ago. A high psa level had him and his doctor worried he might have the disease which can be slow growing. He got a biopsy which came back normal, but that process wasted his money, the Health Care Systems money, not to mention costing him lost time and anxiety. I spent that whole year between the first biopsy and the second biopsy preparing to die. I wasnt enjoying living. I was scared of the possibility that i might have cancer and that i would die. Reporter the organs most overtested for cancer this panel says include thyroid, breast, prostate and lung. Todays announcement is hopefully a big step in a long process. Some of these lesions are not aggressive and actually dont need to be treated and can be watched. Will there be some pushback . You bet there will, but there is no smoking gun. This is not an attempt to get Insurance Companies not to cover people. Its to make our medical system work smarter for us, and the next thing i think, brian, well have to stop defining cancers by organ systems and recognize that cancer of the lung has some properties in common with other cancers like of the prostate and ovary and start to treat them with regard to their genetics. So its about language, yes, but also prioritizing in whats become a testcrazy nation. Exactly. I mean, if you start ct scanning and mriscanning everybody, youre going to find things that dont look normal. Does that mean you should take everything out and start treating people . The answer is no. We know we waste onethird of our medical expenditures on things that arent worth chasing or arent worth treating, and you know what . We hurt people in the process, so the smarter we make this, the better we make it. Thats why today was so impactful. Nancy, thank you as always. To the journalists sitting in the back of his plane flying him back to the vatican from rio, the popes words today during a surprise airborne News Conference seemed if not revolutionary certainly newsworthy and historic in terms of the Catholic Church.
