Dark skin spot?

hi, i am a 30 year old female. i noticed a dark spot on my chest about a year ago, the size of a pinhead. since then, it has grown slightly and i was wondering whether i should be concerned. i should also mention that i have quite a few skin tags and seborrheic keratoses on my chest (my mom and sister have them too). pls let me know asap, as i am really freaked out...

my best advice is to go and see your doctor asap, just to be sure.

go to a skin docter. i go all the time because skin cancer runs in my family if u don get that place taken care of it may lead to something very serious
