update, I had been avoiding this.
I posted this on 2/7, I 2/14 we found out the tumor was in fact an aggressive cancer (Rhabdomyosarcoma), and had grown so large, and started to effect nearby lymph nodes, there was not a choice and we had to amputate. Life and death choices become crystal clear when you need to make them. So on 2/15 she had surgery.
She has been super tough, and was up and walking a hour after surgery, home in 2 days and doing almost everything she was doing before already and is ready for the next fight. She has been truly inspirational to our whole family.
Tomorrow we have the follow up from surgery to hear the pathology results and hopefully negative margins, and the follow up plan for chemotherapy, even with the tumor removed she will need chemo due to the aggressive nature of the cancer. (She did have a bone scan with contrast and a CT scan of her whole abdomen pre-surgery that showed no other signs of cancer).
It has been a ton in a short time, but it really makes you value every day you have.
