These are known as interval cancers. Most of these interval cancers are newly detectable cancers that developed since the last screening appointment. However, some interval cancers were visible at the last screen, but were not recalled for further tests because the signs of cancer were subtle and thought to be normal, or were missed completely. These “minimal signs” and “false negative” interval cancers make up about half of cancers that are detected through symptoms in the period after a routine screening round .
The introduction of AI can possibly improve the number of breast cancers detected at screening, but this depends on AI's ability to detect cancers that would otherwise be overlooked or missed by radiologists during screening. We will evaluate the potential of AI to prevent interval cancers before they occur.
