Hi @Haiz Sorry to hear about your mom's passing. I was initially diagnosed with DCIS on both breasts and did a bilateral mastectomy 4 months ago. I also did a CT scan and bones scan before my surgery but didn't find anything. However, the pathology results found a micromet in my left lymph node. So, 4 cycles of chemo with CT was recommended. BC is such as complicated issue and everyone's treatment is different. I opted for the chemo because I don't want to regret not doing anything while I can and I just competed my final treatment two days before. Your treatment team should be able to recommend what is best for you, or you may also consider seeking a second opinion before making any decision.
Hope you have some good news from your treatment team.
Another note, talk to your treatment team about exercise, when you can start, it's very important that you get your range of motion back. It's been four months since my surgery, while I'm have most of my range of motion back, the surgical areas can still feel tight and I'm still doing stretching exercise everyday.
Sending you lots of love! Take care <3
