IUDs may offer cancer protection

Really interesting new study of 20,000 women suggests that the use of IUDs might reduce the risk of both major types of cervical cancer, even in women who contracted cancer-causing HPV. The researchers speculate that the IUD's presence—it is, after all, a foreign object in your lady bits—may serve to stimulate immune responses that fight off HPV infection early and prevent it from progressing to cancer. This needs follow up. But it's intriguing. (Via Colleen McCaffery)
