I am so glad you are being vigilant in staying aware of changes in moles and other spots. While every spot is not skin cancer, it is a good idea to have your skin examined by a dermatologist if you are noticing new spots or changes to spots and moles you have had for a long time.
I am including a few articles that address self-exams and how to note important changes and irregularities.

This one lists the ABCDEs of melanoma. I use it during skin checks to note changes before contacting my dermatologist for a skin exam.
