As I have noticed you have moles that greatly varied. Moles that often look different from one another and are usually with bigger diameter than normal moles, are known as dysplastic or atypical moles.
People who have them are at an increased risk of melanoma (they usually resemble melanoma). Sometimes a melanoma begins within a dysplastic nevus.
Enlargement of a previously stable mole or appearance of a new mole after age 40 always raises suspicion.
I don't wanna cause you unbiased worries, but, there is no need to delay the appointment.
