Hello there My step dad was diagnosed with Alzheimer's 6 years ago and has recently been diagnosed with bowel cancer. The doctors want to remove part of his bowel but my Mum is not sure whether it is in his best interest in terms of the effects of his quality of life after the op. As I have joint power of attorney along with another family member, I may be called on to give my consent. However, I also have the same concerns and was wondering if anyone could offer any advice or share any similar experiences. My step dad is 84.
