Is it normal to gain new skin spots and freckles if i've never have b4? i'm 25
I'm 25, something like one week after I turned 25, I right away noticed one morning that some freckles appeared on the top of my hand/ wrist area. A couple on my other hand, but I imagine I got more on the left hand because that one may receive a little more sunlight from me driving. My boyfriend noticed these spots right away too, and said, "what's that? That wasn't there before." I'm half Mexican/ Spanish with a little bit of American Indian and I have always had an even skin tone. These freckles vary in size up to about 3mm and on my left hand I have like 20 of them. My sister says they are just sun freckles, but I'm worried cause I've tanned before, and this never happened, I wasn't even in the sun that much near that time, just in the car, ugh.
Also, to add to this, I have some weird spots that are appearing on my chest. There are two in between/ below my cleavage line, and two on my right AND two on my left breast on the bottom inner breast areas that are pretty much identical on each side. The Size of the spots are about 1cm in diameter and they are reddish in color, and rise a tad bit above the normal skin. I only noticed the ones before because it is apparent in my cleavage line, but then my boyfriend pointed them all out. At first I dismissed the first two that I had noticed as maybe some indentations or imprints from using underwire bras, and since all of those spots are sort of symmetrical, I was thinking that maybe it's because of the daily use of a bra. I noticed these spots a couple of years ago and they are slowing growing in diameter. They are still there even when I don't wear an underwire bra for a couple days. I google imaged skin cancer for comparison, but I don't see too much of a resemblance.
Either way, I need advice and (please wear sunscreen, haha.)
