Alex, uite inca un motiv sa iti faci un scan mai ales daca fumezi. X-rayul normal vede problemele abia cand e prea tarziu. In state se intampla altceva. An de an se fac 80.000.000 de CT scanuri. Adica 1 din 3 americani face un CT pe an (majoritatea sunt torace si stomac). Probabilitatea de a muri de cancer e de 42%, iar riscul aditional dat de CTuri datorita radiatiei e de 0.7%.
In a 2009 study from Brigham and Women's Hospital in Boston, researchers estimated the potential risk of cancer from CT scans in 31,462 patients over 22 years. For the group as a whole, the increase in risk was slight — 0.7% above the overall lifetime risk of cancer in the United States, which is 42%.
