Endometriosis is a chronic disease that affects "5 1/2 million women and girls in the USA and Canada, and millions more worldwide." The Endometriosis Association (EA), a non-profit, self-help organization, is dedicated to "providing information and support to women and girls with endometriosis, educating the public as well as the medical community about the disease, and conducting and promoting research related to endometriosis." The EA Web site contains background information on the disease, its causes, symptoms, and treatment options. In addition, the site provides access to available resources such as books, CD's and tapes, videos, newsletters, support groups, and family programs. For anyone with endometriosis or affiliated with a relative or friend who has this painful disease, the EA site is an excellent place to go to find helpful information that can assists with one's recovery.
