I couldn't take any of the hormone blockers and I will be 4 years from diagnosis of invasive lobular breast cancer and mastectomy in November of this year. So far, so good but I guess the magic number is five years and then ten years after that. I'm keeping my fingers crossed. If I find out any different at my 6 month checkup in June, I'll let you know (I hope I have no news...that's the good news). Also, I was diagnosed original about 6 years ago with LCIS (Stage 0 cancer) and then I had invasive 2 years later.....I was unable to take Tamoxifen and unfortunately, I got invasive cancer......but, it's been clear sailing since treatment for my Stage 1 cancer. Hopefully that's not too confusing.
I would also love to hear from anyone else who was unable to or chose not to use the AI hormone blockers and how they are doing...either no recurrence or recurrence
Thanks for asking this question.
