My mother saw some white spots(5-6 spots) 2-3 years ago on her legs, but she ignored it because she didn't think that this is leucoderma and the average size of each spot was so small(1 mm diameter), but before some days she find size of spot is increasing(2-3 mm diameter). and she found some spot on her chest. Is there any permanent treatment available for this? If yes then what, where and how? What will be cost for it?
