My undifferentiated sarcoma was removed from my knee and on my five year anniversary of being cancer free several spots were seen in my lungs. I’ve had surgery to remove the two largest nodules a few months ago. Now just waiting anxiously until the next CT scan to see if other nodules have grown and can be surgically removed. I’ve joined a sarcoma cancer support group (virtually) hosted by Memorial Sloan Kettering and would be happy to share the link to application if you’re interested.
