How can you tell whether the mole is harmful or not?

Suspicious mole: Any mole that changes size, color, or have irrregular borders should be biopsied. If you have fair skin or history of skin cancers or family history of skin cancers, you should see your dermatologist to survey your skin. It is impossible for you to see every spot on your skin.

If worried, see Dr.: Hard to tell sometimes, but some moles are more worrisome than others. A dermatologist can look for, examine, and biopsy suspicious moles. Concerning signs are: asymmetry (one half of the mole growing faster than the other half), border irregular, more than 1 color in the mole, diameter more than 6mm, and the mole is elevated above the surrounding skin.
