Does the physical examination do CT and increase and suffer from the cancer risk
Q: Popular physical examination during these years. Because I belonged to the top management team in the company, the personnel department arranged three advanced physical examinations for me in one year recently, make CT each time, also make PET. Heard from news a few days ago one discovered recently that doing CT causes cancer in U.S.A., is that true? Health control teacher: After 2003, Chinese health consciousness was woken up. Fixed physical examination is a very fashionable thing. The physical examination project is done more and more much, the price of physical examination is more and more expensive, the instrument and equipment are more and more advanced. In fact this is essential preventative fixed physical examination alienation once. The more well what the physical examination is not done is. You if the body health status is good, the so-called " physical examination of the health " having nothing to do with the disease three times in one year ,It is unnecessary, also waste medical resources, may be harmful to health. Really, the magazine of U.S.A. " file of internal medicine department " delivered a research report recently, it is widely different to find the radiation dosage level of what CT scans and uses. Use the too high dosage to do the chance that CT can get cancer after obviously increasing. It is a kind of not invading medical check that CT scans, combine special X ray apparatuses and computer technologies and produce the detailed health fault picture, can help the doctor to find out about internal situation of the body ocularly, have a few gold eyeball pinkeye like Sun Wukong. Over the past 30 years, explosive growth has appeared in the application which U.S.A. CT checked, become 700,000 persons to become 70 million persons by every year 2007 from every year 1980. The research originate from, find, have more thanth the intersection of brain and the intersection of apoplexy and patient make CT check ever in one hospital, Los Angeles of U.S.A., 2009, the dosage to check exceeds normal CT and checks octuple of the dosage. Researcher make CT of patient that CT check check radiation dosage, assess to 1,119, find that varies with each individual, radiation dosage differs significantly. For example, make head CT, the median of the dosage is 2. The radiation dosage that some people accept is 0.3, others are 6. The intersection of belly and CT it checks radiation to be can low to reach 6 in quantity, up to 90. Researchers estimate according to the discovery above, if has made CT coronary artery radiography during 40 years old, have a person who will catch cancer in women every 270 people sooner or later, will have a person who will catch cancer in men every 600 people sooner or later. Make at the age of 40 head CT check, women have one who caused cancer sooner or later in the every 8100 people, have a person who will catch cancer in men every 11080 people sooner or later. The national cancer research institute of U.S.A. has a research that estimates, 29000 cancers that will take place in the future in U.S.A. relate to the fact that CT 70 million times done in 2007 checks too. Among them, making has 14000 people who will catch cancer in the person whose belly and pelvis CT check in the future; Making has 4100 people who will catch cancer in the person whose chest CT checks in the future; Making has 4000 people who will catch cancer in the person that head CT has checked in the future; The philtrum which is done CT coronary artery radiography has 2100 persons to catch cancer in the future. Caused the philtrum of cancer these future that estimate, 1/3 of the people made CT inspection among 35-54 years old; 2/3 of the people are women. According to the above-mentioned result of study, researchers propose, if the doctor wants you to make CT inspection, you should ask a doctor: " What advantages does this CT have on treating my disease to check? Does this CT check whether the result will change your healing solution to my disease? If will change the healing solution, what advantages does this change have on my health? The research above tells us, the more important thing is, if not out of treating the ground of eye, CT checks undoubtedly " Hurt looks right and fetch it heavily two times " ,Should not do. In U.S.A., because nobody will do CT, check by preventative physical examination, so, there is no research in this respect. But if you think scientific evidence reveal, even if sick already, for diagnose, need, either should make CT, check at will, then, the healthy person unless the brain enters water, how could do probably carcinogenic CT to check? For one's own health, we are facing CT and should ask while checking, is it necessary to make CT and check? Can achieve the basically the same goal with other technology without radiation, for example, whether can substitute through the way that supersonic wave is checked?
