Hello, I've always had moles on my body. Recently, I've been told I should see a dermatologist. As I age they seem to appear more and more frequently. A few years ago, I developed a 3-4 inch patch of darker skin on my lower back. This is not concerning to me because i was born with a similar birth mark on the opposite hip, however, my concerns arose when 20 or so moles decided to populate the darker patch of skin.
Is this something I should be weary of?
