Thank you! My father, 85 year old has a mass in his right atrium and the thoracic surgeon says it's a angiosarcoma. The cardiac doctor, Thoracic surgeon, cardiac thoracic surgeon are in disagreement of how to proceed. He has had a Colonoscopy, Endoscopic (?) beginning in September, CAT, Echo, MRI all in November, a PET 12/4 and the first appt for the biopsy the radiologist would not do, because the lymph node where they want to take it from was too close to the heart for him 12/19. The thoracic surgeon we saw yesterday will do the biopsy but he believes surgery is best with radiation or chemo followup once they know what it is, where the Cardiologist still wants a biopsy cause he feels it's a tumor and the cardiac surgeon believes it's lymphoma. My father was in very good health before July/August and has not eaten (2 bottles of glucerna, maybe a but of soup) for the last month and just started sleeping a few hours here and there. He is losing alot of weight. My question to you without knowing all the details I know...should we go with a biopsy, go with surgery and removal, we live in Orange County in CA -should I go to City of Hope, USC, UCLA - somewhere more equipped to handle this? I appreciate any idea you might have. Thank you, arlene
