Yesterday was pretty uneventful for my mother-in-law. There was an attempt at putting a stent into her bile duct and performing a biopsy on her pancreatic tumor. However, since her potassium levels were so low, they were afraid to put her to sleep. They began dealing with those electrolyte levels. With any luck, they will be able to place the stent and do the biopsy today. That will also be when we know, for sure, whether this is cancer or not.
