Will a cancerous mole continue to evolve/grow or change in shape/color over a weeks or months period?

You may watch and wait. If the mole doubles in size, becomes irregular in size, shape or color, bleeds, ulcerates or develops a nodule, see a doctor. Wish you good health!

HOW DO YOU KNOW IF THE MOLE IS CANCEROUS? If you have a mole that is brown -black and it gets darker over time and you have a history of being in the sun than consult a dermatologist right away. Other moles can grow or be red in color and brown but that doesn't mean they are cancerous. Always seek out a dermatologist for a biopsy to see if any moles are pre-cancerous or cancerous.
