Hi,Just read you're story and thanks for sharing. Mine was borderline, and got a wide excision done and second surgey for a margin. It's such an unpredicatable tumor, and I'm finding that for me it's just a part of my life now to check, and sometimes double check. Like you I have a fibroadenoma that often appears during my periods, and I'm worried that will turn out to be PT one day. Anyway... I think there are a few on this forum that has had a malignant PT, and from memory they have had Mastectomy but no further treatment. Hopefully, they'll read you story and share their experience with you.I know it's hard to keep positive. But if you need support, you can always come on here and chat. Take Care.Rosie
