2nd local Recurrence - Risks/Benefits WBR?

Hi, so sorry to hear about your situation, but boy, can I relate. I am trying to negotiate a path to a cure and stay sane. After lumpectomy and WBR in 2012 at age 59 for stage 1A hormone-receptive BC, I had a stage 1A recurrence in same breast in July 2019, treated with a mastectomy, latissimus dorsi reconstruction, and AI medications. In December 2020 I was diagnosed with a recurrence in the LD flap, but no metastasis, at least as yet. I am being treated with comb of Fulvestrant injections and Ibrance oral meds (usually given for metastatic patients) to shrink the tumors (now multiple) before more surgery to remove the flap, cancer, and implant (which was in addition to the LD flap), as recommended by my breast surgeon and radiation oncologist, who wants to do more radiation. However, my regular (super) oncologist thinks I can do the targeted therapy indefinitely if there is no progression. My 3-month MRI shows very slight diminishment of tumors (they are multiple this time). Surgery will be tricky because there is little good skin left for closure, even flat, and a TRAM flap could be needed next, which I think puts me right back at risk of BC invasion and requires an even more grueling rehab. Hard to imagine having a rarely recommended second course of radiation on top of this. I too am finding a dearth of info on second recurrences and effective treatments. I am very active and athletic so even the thought of living with the ramifications of the second surgery and radiation sometimes seems worse than giving up. I too am having trouble finding good info and studies that look at treatment for second recurrence, particularly re radiation and what to do if cancer is back and there's no good skin left... I'll be happy to share anything I come across. Am also thinking of going to Mayo for a second opinion on next steps following at least another 3 months on the targeted therapy.
