Would you mind sharing what leiomyosarcoma is? Is it in the bone? How did you know you had it. What were your symptoms. The possible chondrosarcoma(still need biopsy to confirm) I have in my femur is large 10cm x 2.2cm and was only accidentally found on a bone scan because my oncologist wanted to show me the breast cancer I have did not spread so she ordered a bone scan. I understand a chondrosarcoma is generally not breast cancer that has spread and I am thankful for that and really thankful that I kept bugging my doctor with the fact that I just did not feel well. I’m curious if you physically felt sick before being diagnosed.
