Final answer:
The 'A' in the 'ABCDE' rule for evaluating melanoma stands for Asymmetry, indicating that the mole should look equal in size from side to side. This mnemonic also includes Borders, Color, Diameter, and Evolving, which are all characteristics to watch for when self-examining moles for early signs of melanoma.
Step-by-step explanation:
The "A" in the "ABCDE" rule used in evaluating melanoma stands for Asymmetry. This rule is a mnemonic device given to patients by doctors to help with the early detection of melanoma, which is the most severe form of skin cancer. When observing a mole, if one side does not mirror the other, it is considered asymmetrical and could be an early sign of melanoma. Other aspects of this rule include:
- Borders - the edges are irregular in shape.
- Color - the mole shows varied shades of brown or black.
- Diameter - it is larger than 6 mm (0.24 in).
- Evolving - there are changes in shape or size over time.
It's very important to conduct regular self-examinations of your skin and consult with a healthcare provider if you notice any of these characteristics. Early detection of melanoma significantly increases the chances for successful treatment.
