Anaemia drugs up cancer death risk:

Treating cancer patients with anemia drugs increases their risk of blood clots and death,US researchers said, confirming concern about these widely used drugs.Researchers said the drugs,including Amgen Inc’s Aranesp and Johnson & Johnson’s Procrit, raised the risk of death by 10% in patients who took them,a finding that could not be explained by the higher blood clot risk alone."Our findings,in conjunction with basic science studies,raise the concern that the drug may be stimulating cancer and shortening cancer patients’ survival," Dr Charles Bennett of Northwestern University in Chicago said in statement.
