Hi, Both my parents have multiple cancers, my dad has prostate cancer which has spread to his chest bone and now his intestines. My mom had kidney cancer that has spread to her lungs. My dad has also high potassium levels,, but after a recent trip into hospital to have his fluid drained, when they found they couldn't cannulate him any more, he decided to refuse any more attempts. We all understand the complications that this could cause. Today his potassium levels were recorded at 8.2 and he was asked to go back into hospital so they could start treatment. He has talked it over with my mom to a great depth and has decided not to go in. He has not been told how much time he has left. He was first diagnosed 8 years ago. Mom was diagnosed 5 years, she at the moment is taking chemo medication and it is keeping it under control at the moment. .
