Radiation for Lung Mets

Thanks to all who responded to my post. I will certainly ask my onc. about all of these possibliities. Also, one recommendation was to get radiation. Do any of you have any info on this or have had it done. I would appreciate your responses on this as I think I have had evough chemo. Maybe radiation can shrink the tumors. I asked my onc about this many times before, but she said radiation to lung mets is only done if you are in pain or having trouble breathing. It is used mainly to relieve symptoms. I don't have pain or trouble breathing. Please let me know if any of you know anything different on this.
