Truth is we have no idea where the limit goes (if there even is one as we're all individual cases) and wine isn't considered as detrimental as hard liquor and you certainly didn't drink a lot if it was only 2 a week. But I'm glad to hear your resolution! As someone else wrote here once, why tilt any odds out of your favour. I also had dysplasia for around 8 years before it turned into cancer and I still have no idea what caused it.
