I will pray for you and your husband. I am a patient at Mayo Rochester MN. They have treated my Lipo sarcoma on my chest/ shoulder beginning in the 90’s. It is now aggressive. I will be going through a month of radiation and then a Four Quarter Amputation of my arm/shoulder. It will not be easy but I am in the best hands and have confidence in my Drs. Most medical centers do not have the experience in treating our disease. I would recommend taking your husband to one of the main Sarcoma Centers like Mayo. Sorry you both have this challenge.
