New Primary cancer

[monkeygirl62]

I have stage 4 metastatic breast cancer ER+ and her2 negative and been on Ibrance and letrozole for since December 2023 though I was diagnosed August 2023. Long story that I mentioned in a previous post. I had a recent biopsy of my upper left lung since I have lung mets. The last biopsy I had said it was all breast cancer. This biopsy says it's small cell lung cancer (yes I am a smoker and it's rare in nonsmokers to get it but women can - only though about 2 -3%). I have been crying a lot and I know this cancer is aggressive and fast growing. But get this this one tumor I have dad since the beginning of being diagnosed with breast cancer. It's been on all the scans, hasn't grown but didn't shrink so it's not acting like small cell lung cancer no do I have any symptoms and I have had it for a year. I feel devastated and depressed. I see my oncologist today and my adult kids are going with me. Anyone else have any other secondary primary tumor?
