...potentially toxic radiation therapy, or to opt for a mastectomy, removing the entire breast and contending with the disfigurement that entails. The decision typically rests on where and how widespread the tumors are. It's no wonder, then, that more and more women are relying on high-tech MRI (magnetic resonance imaging) scans to help them examine their cancer and choose the right treatment...
...that may not be such a good idea, say researchers in a commentary appearing in CA: A Cancer Journal for Clinicians, a publication of the American Cancer Society. The authors looked at studies pitting preoperative use of MRI, which relies on magnetic waves, against mammograms and similar tests that use radiation to take pictures of breast tissue. Researchers found that women choosing MRIs often ended up with more aggressive surgery - much of which wasn't necessary - than women who did not use the scans. What's more, employing the newer and more sensitive MRI technology did not improve a woman...
...studies have shown that lumpectomy combined with radiation therapy yields the same survival and recurrence rates as mastectomy; while more cancer may remain in a breast following lumpectomy, these lesions are generally destroyed by the radiation, which gives the two procedures the same outcomes. Yet women receiving an MRI tend to choose the more invasive approach. (Read about the benefits of post-cancer weightlifting...
...expensive equipment. There are a whole range of reasons why that might be true, but the point is, is that it's not like people out there are - would automatically be prevented from getting CAT scans if we just tried to think when is a CAT scan or an MRI working and appropriate in improving care and when...
...unlikely that No Lie MRI will give up anytime soon - the company claims that the potential market for its technology could exceed $3.6 billion. While that figure seems exaggerated given legal safeguards against using polygraphs, Greely estimates that if fMRI lie detection became admissible in court, the industry could easily be worth more than a billion dollars per year.
