white spot known as vitiligo is chronic condition.
you have taken most of the medicine ,so you also come to know about it.
photo therapy is one of the best treatment.
your worry regarding cancer is right.

i hope i answered your question.

Hi thanks for writing here.White patches or vitiligo is always challenging disease for any dermatologist.Most commonly treatment are steroids and phototherapy ,but sometimes these are not effective.Now days many surgical procedures are available for treating vitiligo like punch grafting,suction blister grafting,etc.They give good cosmetic results.But your vitiligo should be stable (no new lesions for 2 years),You can consult a dermatologist and try for surgical methods if you have stable vitiligo.Also since it can be associated with many other diseases ,get your blood checked for sugar,thyroid profile ,and a complete blood count.Lukoskin is a herbal medicine and it is also a form of phototherapy,you can try it.If in case your vitiligo is unstable then it can be made stable with oral steroids and immunomodulators and then surgical treatments can be achived.
