If a mole gets bigger or becomes more raised over the years, does this mean it's cancerous?

Need Medical checkup: Moles coma in many forms. Most of them are benign. But if a mole is changing its colors and starting to grow, it may need to have abiopsy which is best done by your family doctor or by a dermatologist who will first examine your mole to check if it appears to be benign or suspected melanoma. A biopsy is the final answer to determine if it is cancerous or not.
