Does an itch at the vaginal opening indicate cancer of the cervix or the vulva ? just started an itch after using baby wipes while camping. not sexually active in the last year?

Rarely is vaginal itching caused by cancer. The most likely issue may be vulvar irritation from a vaginal infection. if the itching persists without using the wipes or colored toilet paper then contact your GYN MD for assessment.

What you described is likely a primary irritant or allergic reaction to the wipes. If the symptoms persist more than a month after discontinuing the use of wipes, it would be prudent to see a gynecologist. Wish you good health!
