In the ABCD checklist, what does 'B' stand for?

In the ABCD checklist, 'B' stands for "Borders," which refers to the edges of a mole or growth on the skin. Specifically, it is used to assess whether the borders are irregular or not. Normal moles typically have smooth, even borders, while those that are potentially cancerous often have uneven, notched, or scalloped edges. The presence of irregular borders is a critical factor in evaluating lesions for signs of melanoma.

This method helps in identifying suspicious moles early, where early detection can significantly improve treatment outcomes. Regular monitoring of moles and understanding the significance of border characteristics are essential practices for maintaining skin health, especially for individuals at higher risk of skin cancer.
