What is the meaning of "interval cancer" in breast cancer diagnosis?

The term "interval cancer" specifically refers to breast cancer that is diagnosed between scheduled screening mammograms. This type of cancer might not have been visible during the last screening but is later found upon further investigation, often when a patient reports symptoms or during a follow-up exam. The significance of interval cancers lies in the understanding that they represent cancers that were missed during the previous screening, raising considerations about the effectiveness and timing of mammography protocols.

In identifying the meaning of interval cancer, it is essential to recognize that it contrasts with cancers diagnosed at routine screenings. This aspect of timing is crucial in evaluating screening practices, as interval cancers may suggest the need for improved detection methods. Other options, while potentially related to the topic of cancer diagnosis, do not align with the specific medical definition of "interval cancer" as defined in breast cancer diagnostics.
