Dermatologist vs Gynecologist for Lichen Sclerosis?

Good-morning-
A few months ago at my full body skin check the derm diagnosed Lichen Sclerosis: "You don't need a biopsy, it's unequivocally LS." She then said Gynecologists treat LS with heavy duty topical steroids, which Dermatologists do not. I consulted with a Gyn who agreed I likely have LS but recommended a biopsy to be certain. She also said Gyn's do in fact recommend daily steroids to reduce inflammation, even if a person is asymptomatic, because the inflammation is believed to be the source of the increased incidences of vulvar cancer in LS patients. I'm essentially symptom-free, but don't want to ignore it. How are others treating their condition? Are you managed by your Derm or Gyn? Taking daily steroids even if asymptomatic? Thanks!
