Controversial Claim

" Health news tonight if confusing and it is a possible change to decades of conventional wisdom about cancer. The American Cancer Society now reports the way we look for some forms of the disease may not be doing us any good at all. Of course for years doctors have been telling women that mammograms can help save lives because they can detect breast cancer in its early stages -- and early treated early. Same thing goes for men and prostate cancer screenings but now many researchers saying much of what we think we know about checking for the disease could be all wrong. The -- fox sport correspondent Jonathan Hunt has been looking into what was a I don't know a confusing set of paperwork."

" Yes -- this doesn't really steps seem to change conventional wisdom more tornado on its head."

" By claiming in essence the doctor isn't doing too much screening for cancer."

" Researchers arguing the latest edition of the journal of the American Medical Association published today. That screening for breast and prostate cancer in particular can often find cannon says that actually don't need to be treated at. Am left alone would never spread or kill. As evidenced researchers point -- that the huge increase in screenings has not brought about. A similar reduction in the number of cancers of the deadly they say for instance the breast cancer diagnoses have gone up by 40%."

" But there has only been 810% decrease."

" In cancers that have spread beyond the breast to other areas of the body in other words the increasing screenings. It's not catching a similar number of deadly cancers. The American Medical Association says screenings are important. But the patient should know all the facts."

" The more you know about your risk and the benefits of of a screening test. As well as what the screening tests may create just follow it as far as other tests that have to be done. Very important for you to have that discussion so that at the end of the day you know what of the things you're doing to keep yourself healthy. But some doctors say this research risks turning patients away from screenings that they say off saving lives."

" Screening works. And doctors just need to decide of -- once they have the information once they have the diagnosis when is the appropriate time and what is the appropriate type of treatment for the patient."

" So this is clearly a very complex issue as you just heard even doctors -- if you all confused about what all this means. So it seems. But the experts at -- comes in that way Jonathan Hunt thanks very much a marine."
