Moles can grow. Uneven edges and/or change in the surface of the mole can indicate it may be cancerous. It grows and has irregular borders.

a mole can grow, and yes you need to see a Dr if it changes color or has a jagged shape to it. you should have your moles checked by your Dr. anyways, if he has any suspicions he will send you to a dermatologist. Yes a mole can grow. And if it’s a smaller mole you’re concerned about, the dermatologist will usually just remove it than to take chances.
