The Association and Relation of Blood Group with Lung Cancer in Erbil Governorate

Abstract

Lung Cancer is one of the leading causes of cancer deaths in the U.S. It is expected that  about   180,000   new  cases  will  be  diagnosed   within  the  U.S.  this  year,  and  of these, about  160,000 people will die. While the incidence of lung cancer has been declining in men since the  1980s, it is still rising  in women.  The most well  known  risk factor  for lung  cancer  is  cigarette  smoking  (which  has  been  linked  to 85 to  90 percent  of all cases).  Other  well  known  risk  factors  include  exposure  in the  workplace  to  certain substances  (including  asbestos and some organic chemicals),  radiation  exposure,  radon exposure  (especially in smokers), and even second-hand  environmental  tobacco  smoke. Because  of the  close associated  of lung cancer with cigarette  smoking,  It is expected that  this strong risk factor  possibly overwhelm   blood type differences.
