Minimum Latency & Types or Categories of Cancer Revised for WTC Program

The WTC Program Administrator has determined minimum latencies for the following five types or categories of cancer eligible for coverage in the WTC Health Program:

(1) Mesothelioma—11 years, based on direct observation after exposure to mixed forms of asbestos;

(2) All solid cancers (other than mesothelioma, lymphoproliferative, thyroid, and childhood cancers)—4 years, based on low estimates used for lifetime risk modeling of low-level ionizing radiation studies;

(3) Lymphoproliferative and hematopoietic cancers (including all types of leukemia and lymphoma)—0.4 years (equivalent to 146 days), based on low estimates used for lifetime risk modeling of low-level ionizing radiation studies;

(4) Thyroid cancer—2.5 years, based on low estimates used for lifetime risk modeling of low level ionizing radiation studies; and

(5) Childhood cancers (other than lymphoproliferative and hematopoietic cancers)—1 year, based on the National Academy of Sciences findings.

According to the James Zadroga 9/11 Health and Compensation Act of 2010 ("Act") (42 U.S.C. §§ 300mm to 300mm-61), a determination that an individual's 9/11 exposure is substantially likely to be a significant factor in aggravating, contributing to, or causing an individual’s health condition must be made based on an assessment of the following: (1) the individual's exposure to airborne toxins, any other hazard, or any other adverse condition resulting from the terrorist attacks; and (2) the type of symptoms and temporal sequence of symptoms (42 U.S.C. § 300mm-22(a)(2)). With regard to the temporal sequence of symptoms, cancers do not occur immediately after exposure to a causative agent and they usually take many years up to several decades to manifest clinically.
