Hi..I've been trying to get an appointment with dermatologist however their computers are down for two days now. So I have been driving myself crazy trying to figure out if this small, dome shaped, clear thingy next to crease of nose is cancer? I noticed it maybe two months ago. Looking at it with a magnifier it has a tiny indent. A few weeks ago I noticed a speck of blood and dabbed with a tissue. Just a TINY bit from middle. So I thought whatever it was will heal . But the dome, clear with center indent is still there. Not noticeable to others so it's very small. I'm 61 with fair skin and yes quilty of much sun exposure without sunscreen . Anyway to tell the difference between just harmless sebaceous hyperplasia since photos I've seen look so similar to basal cell? Thank you.
