The extreme exposure to light UV is most common reason for developing dyspalstic moles.
Although, the susceptibility to have them is usually inherited.
People with multiple dysplastic moles, need to have regular checks (systemic exams when dermatologist may photograph your skin so that changes in your moles can be detected at follow-up visits), because individuals with a single dysplastic mole on their bodies have a twofold risk of developing melanoma.
Dysplastic moles have characteristics similar to melanoma, but, only very few dysplastic moles actually turn into melanoma and they do not need to be removed routinely.

Do you feel some new and weird sensations on the two suspected spots?
How they look?

Thank you so much for replying. No, just that they are similar in color. That is all....since I have had these exisions, I have been seeing my dermatologist every three months and it seems every three months she shaves a spot off of me and I end up going to get an exision.
