hello there. I was recently diagnosed with a 6by 2by 6 cm mass on my Thymic. I went to the ER with heart attack symptoms on the right side, this is when they found it in a cat scan. I have been to Carti a cancer center. All my blood work is fine. My doctor made it seem as if it was nothing. Went to UAMS out of Little Rock they don't know what to do. My Venogram was normal. I'm still in pain but seem like the doctors are making it out to be all in my head. I'm scared. I need answers. I have two children and I'm young. Can anyone help?
