Re: doctor feels softball size lump, CT scan shows nothing
CT scans can miss some cancers, but only usually when they're very, VERY small...a softball sized lump would not be missed by a CT scan.
However, you did mention that she has a hernia. It's quite possible that the lump is a portion of her bowel that is protruding through the herniated spot. If the hernia is on the right side, then that's probably what's happening...and it means she needs to have hernia surgery fairly soon, before it becomes a major emergency.
