(Reprint-NaturalNews) Most cancer drugs are used to hopefully kill tumors and keep malignancies from spreading. Unfortunately, new research from the Washington University School of Medicine in St. Louis raises serious concerns that Big Pharma’s highly touted class of cancer drugs known as IAP antagonists actually increases the risk of tumors spreading to bone.
“These investigational drugs are getting broad attention right now because they seem to be very effective against primary tumors,” senior author Deborah V. Novack, MD, PhD, associate professor of medicine, said in a media statement “There is also excitement because until now, these drugs have not appeared to have major side effects.”
However, the study by Novack and her research team (just published in the journal Cancer Discovery) reveals that while the IAP drugs target a protein that makes tumors vulnerable to death, the same protein also over-activates cells called osteoclasts which are responsible for tearing down bone. The risk for patients? Potentially, IAPs can trigger the bone weakening disease osteoporosis and, even more worrisome, they may cause metastasis of cancer to the bones.
