9 months ago, my brother was diagnosed with bile duct cancer which had spread to his abdominal wall. He has had several chemo treatments and now just got a new stent. Because of a 100.9 fever, he is back in the hospital. They think he has a bacterial infection but they know it is not staph. It sounds like they are saying “basal line negative” but who knows. Does any one know what they are talking about?
