My huisband has pancrecatic cancer and recently developed a pseudomonas infection. They tell us it is now gone, but he has an artificial hip and a port so we are advised that it can hide there. What is the best way of testing to make sure it is gone? He was diagnosed with a tumor in July 2005 and has responded extremely well with treatment for the cancer and is stil active. We certinly do not want an infection to ruin his progress.
