Wow! You are doing a great job following up and taking care of yourself. From my experience and reading everyone’s story it seems as though there is no perfect answer, darn! My LCIS was discovered when I was 49. I had a lumpectomy and followed up with 5 years on Tamoxifen. I had few side effects though the worst was my uterus started growing significantly so I had a complete hysterectomy. 4 years after I ended tamoxifen, it was discovered that I had invasive lobular cancer. I had a lumpectomy, radiation and am taking anastrozole each day. I am having periods of sharp pain in some of my joints. I walk a lot through rain and snow, I have a regular Yoga practice and eat a plant based diet. When I’m feeling strong I feel like a warrior battling this disease and when I’m not I meditate and remind myself that this is just temporary. All any of us can do is listen to our body and do the best we can each day. I don’t have any known gene mutations but my mother had breast cancer at age 28 and died from metastatic cancer when she was 43. Take care my fellow warriors!
