Be careful — unusual dots on your skin could be a sign of cancer. While freckles and harmless moles are common, spots that change in size, shape, or color, have irregular borders, appear red and scaly, cluster in unusual patterns, or form dark marks under the nails may signal skin cancer. Use the ABCDE rule (Asymmetry, Border, Color, Diameter, Evolution) to check suspicious marks and seek medical advice promptly. Early detection saves lives, so monitor your skin regularly, protect it from the sun, and never ignore changes.
