The claim seems to be somewhat misleading. In the article, the author makes strong claims that research shows birth control is a serious contender to cancer without giving any resources to back up the data. The website, WebMD, is also not an extremely reliable source, as people can edit and change articles. There are, however, reliable sources for IUDs possibly reducing the risk of ovarian cancer. However, the main claim made is that birth control causes cancer, which is not backed up or fact checked in the article. The National Cancer Institute does explain that oral contraceptives increase the risk of breast and cervical cancer, but the article does not state this information.
