On Jul. 1, 1944, the Public Health Service Act, P.L. 410, 78th Congress, provided that “The National Cancer Institute shall be a division in the National Institute of Health.” The act also revised and consolidated many revisions into a single law. The limit of $700,000 annual appropriation was removed.

Today, the NCI remains part of the NIH, which is one of 11 agencies that compose the Department of Health and Human Services (HHS).
