We encourage individuals and organizations to link to the National Cancer Institute (NCI) Web site (http://www.cancer.gov) and to the Spanish language site, Cancer.gov en español (http://www.cancer.gov/espanol). The source can be cited as follows:

The Web site of the National Cancer Institute (http://www.cancer.gov)

The NCI Web site is periodically revised, and content may be deleted or moved. We try to ensure that existing links will redirect to the new page(s).

Links from NCI to Other Web Sites

The NCI Web site includes links to external Web sites. These links are for your convenience and to supplement Cancer.gov content. In general, NCI links to:

• Other federal agencies.
• NCI partners (such as a cancer center or clinical trial cooperative group).
• Organizations with which we have a formal relationship (such as a Memorandum of Understanding, license, or development agreement).

Selection of external links is at NCI discretion and does not imply endorsement of external organizations, their products and services. NCI does not guarantee the currency, accuracy, relevance, or completeness of information found on linked, external Web sites.

We reserve the right to remove links to external Web sites that no longer meet our content needs.

Periodic Link Review

NCI periodically reviews internal and external links to ensure that they are still functional and valuable, but you may occasionally encounter a broken link. If so, please send a message to cancergovstaff@mail.nih.gov or use our e-mail form.
