This question is located in the Sample Adult Cancer Screening section.

According to the 2010 and 2015Field Representative's Manuals, this and related questions were asked: determine the practices and knowledge of the public with regard to cancer screening practices. This includes practices that are known to reduce mortality from cancer and some for which evidence of effectiveness is not available. The 2010 Cancer Screening Supplement will be the first time questions about having a breast MRI, virtual colonoscopy, and lung x-ray are in the NHIS.

The Manual further provided the following definition for cancer:

A term for diseases in which abnormal cells divide without control. Cancer cells can invade nearby tissue and can spread through the bloodstream and lymphatic system to other parts of the body.

The Manual also provided the following statement regarding how the data from the Cancer Screening questions would be used:

Together, this information will be useful in developing public health and health services programs to increase... the use of regular and effective screening.
