Hello. I have the uterine leiomyosarcoma as well. Full hysterectomy in 2021. In 2022 removed a tutumor from my lung. I have been told the same information. I have follow up ct scans every 3 months and hope each time that I have clear scans. With all my research and w my drs I find the the same information you have. That I need to remove the tumors are they come up. If I learn anything new I'll post to you.
