My right areola appears to be a little larger and darker on the bottom edge. is this normal? 100% not pregnant ans have no other cancer symptoms?

Not to worry: Slight pigmentation differences are not all that uncommon. Most likely you had some slight irritation in the area at some point, which in turn led to the pigmentary changes you note. Just continue doing your monthly breast exams, and if you notice any other changes in your breast, bring it to the attention of your primary care physician.
