I can understand why you feel like something is missing in the team you are working with. It sounds like the ortho surgeon is continuing to head things up with your treatment despite the fact that these new tumors are not in your limbs and surgery is not an option. He/she may feel that adding another physician who specializes in sarcoma is not necessary, but it doesn't sound like he has explained to you why as an ortho surgeon he is still heading up your care. This is when your sarcoma team needs to grow to meet your current care needs. I would check to see if your radiation oncologist specializes in sarcomas and lung treatment. (Most likely he or she does). Then I would not hesitate to call the Mayo sarcoma department and find out which physician you would be referred to for a consultation regarding metastatic sarcoma tumors in the lungs. Once you know who that would be, you can request a consultation with that physician or ask if that physician should now be involved in your current team of specialists. I hope this helps to navigate the situation and I wish you all the best as you fight this next round of treatment.
