There are three major hospital locations in Fallujah. The main hospital (formerly Saddam General) is located downtown, near the west end. The second is located across the Euphrates River in an area of west Fallujah commonly referred to as the 'peninsula', (due to its shape). The third hospital is the Jordanian Field Hospital located east of the Highway 10/Highway 1 interchange. In 2010, it was reported that an academic study had shown "a four-fold increase in all cancers and a 12-fold increase in childhood cancer" since 2004. In addition, the report said the types of cancer were "similar to that in the Hiroshima survivors who were exposed to ionising radiation from the bomb and uranium in the fallout", and an 18% fall in the male birth ratio (to 850 per 1000 female births, compared to the usual 1050) was similar to that seen after the Hiroshima bombing. The authors cautioned that while "the results seem to qualitatively support the existence of serious mutation-related health effects in Fallujah, owing to the structural problems associated with surveys of this kind, care should be exercised in interpreting the findings quantitatively".
