As you might expect, a multitude of World Wide Web sites deal with aspects of breast cancer. I've chosen sites that exemplify various types of home pages. OncoLink is sponsored by the University of Pennsylvania Cancer Center, with the goal of educating health care personnel, patients, and others. Although OncoLink is partly funded by a large drug company, it does not appear biased.
Editors are M.D.s, backed by an editorial board of oncologists.
As large as it is, OncoLink is well-designed and simple to navigate. Mounted by the National Cancer Institute and frequently updated, it offers a rich variety of government information sources, useful to both health professionals and lay users. This well-conceived large site provides information to breast cancer patients and their families, with a small section geared to health professionals. Information is provided by a partnership of fourteen organizations including the American Cancer Society, Columbia-Presbyterian Medical Center, the National Alliance of Breast Cancer Organizations, and a chapter of the Susan G. Komen Breast Cancer Foundation. A subject index and an internal search engine allow homing in on a topic.
