Hi - my partner has early onset Alzheimer’s and was then also diagnosed with breast cancer - devastating for one so young. If there is a tiny thread of comfort, it is that she forgets about the BC a day or so after treatment or consultation. I add support but without mentioning the c-word, just phrases like ‘you are doing amazing’, come on, let’s go out for a while. I would always advise to let the oncology team know everything about the dementia and keep in regular contact with the Specialist Nurse. Stay strong and smiley and enjoy the many good times ?
