Welcome to HealthcareMagic,
I need to see the lesions to comment if they are actually moles
or something else. To give you a rough description moles (or melanocytic nevi
as they are medically called) are flat topped or dome shaped black or brown coloured 1mm-several cms, papules.
They are common and normal. They may or may not grow in size and new lesions may keep on occuring. There is no medication to stop them for occuring. treatment is limited to surgical removal of individual lesions.
