I would like to ask about what DCIS is classified as for insurance for holidays as many ask has this progressed to breast cancer, when it is in fact breast cancer albeit early. Is this pre cancer or would I be wrong to say it hasn't progressed? I don't want to tick the wrong box. I have had 3 ops and now just starting radiotherapy. Hopefully after that things improve but I'm finding holiday insurance a minefield. If anyone has any experience I would be grateful to hear from you.
