I called an ambulance in 2006, because I thought I was having am heart attack. Drs did xrays and saw a large mass I my chest. My Dr called me on the phone and told me that I had lymphoma and that it had spread to my stomach area. One of the longest and scariest night of my life, had nightmares the whole night. Then tests and removed most of it because they thought is was lymphoma. (Dr said "if he know it was sarcoidosis he wouldn't have removed anything.")
