What could red,flat marks, and not itchy marks mean?

I don’t know what it is. I’ve had it for a year but I didn’t do anything about it because it didn’t bother me at all. it’s kind of small. I’m freaking out right now because I noticed that it’s starting to spread. It is located on the side of my waist near my chest.

I’m starting to get worried because I looked up my symptoms. I can’t find an image to it but all I see is people getting surgeries or dying from cancer from these spots! =( I’m really worried.

Anyways, I’m trying to find a good dermatologist because my current one is booked for one month…ridiculous.
