Dear Editor, Re: “To Your Health” [Sept. 8]: You have some incorrect information on your answer to the 17-year-old that has vitiligo. People with vitiligo do not have an increased risk of developing skin cancer. Also, UV rays such as the sun are good for repigmentation, so an SPF of 30 on vitiligo patches is not necessarily recommended. Please go to www.vitiligosupport.org for correct information. It would be a wise idea to recommend this Web site to the 17-year-old, as well.

[James Heffley responds: You are correct about vitiligo and skin cancer, although there is apparently some controversy about the effect of PUVA treatment (commonly used for vitiligo) on cancer incidence. Thanks for bringing this to my attention.]
