I have noticed these small raised areas in the delicate skin under my eyes. I was told that dark haired,olive skin women get them pretty commonly. They are firm to the touch and look like pimples. I also have found one right on the inside of my nostril and one on the tip of my nose. I was messing with one of them to see if maybe its just a clogged pore and managed to squeeze out this firm chunk of white substance,which left a small dent in the tip of my nose where it was removed. It also bled momentarily ,but now it feels fine.
What are these things? Should I be worried about cancer?
