Which of the following is NOT part of the ABCDE cancer checklist?

The ABCDE cancer checklist is a widely recognized tool used for the early detection of melanoma and other skin cancers. Each letter in the acronym represents a specific trait to look for in moles or skin lesions.

Asymmetry refers to the shape of the mole; if one half does not match the other, it could be a warning sign. Border irregularity describes the edges of the mole; if they are notched or scalloped, this raises concern. Color pertains to the presence of multiple shades within a mole, which may indicate a higher risk of cancer.

Duration, on the other hand, does not fit into this acronym. The ABCDE guideline focuses on specific physical characteristics of the mole rather than the length of time it has been present. Therefore, duration is not included in the checklist, making it the correct answer in this context.
