Cancer related to blood cells is called as Leukemia. Under Leukemia condition, bone marrow produces abnormal cancerous blood cells that crowd out the normal and healthy blood cells. Leukemia is of different types based which blood cell type has become cancerous. White blood cells are more to prone to become cancerous than RBCs and platelets. Leukemia can be acute or chronic and Lymphocytic or Myelogenous. It occurs most commonly in adults above 55 years and children younger than 15 years. The treatment methods used depend on the blood cell affected and whether the leukemia is acute or chronic or Lymphocytic or Myelogenous. Chemotherapy is frequently used to treat leukemia.
The nationwide Geocap case-control study included the 2,753 cases diagnosed in mainland France over 2002-2007 and 30,000 contemporaneous population controls. The last addresses were geocoded and located around the 19 NPPs. The study used distance to NPPs and a dose-based geographic zoning (DBGZ), based on the estimated dose to bone marrow related to NPP gaseous discharges. There was no increase in AL incidence over 1990-2001 and over the entire 1990-2007 period. The results suggest a possible excess risk of AL in the close vicinity of French NPPs in 2002-2007. The absence of any association with the DBGZ may indicate that the association is not explained by NPP gaseous discharges. Overall, the findings call for investigation for potential risk factors related to the vicinity of NPP and collaborative analysis of multisite studies conducted in various countries.
