I'm so sorry to hear about your husband and how this is affecting you. I can imagine how difficult it must be sometimes to process what's happening and know what to do, but please know that there is support and advice on the Dementia UK website including taking care of yourself. The Cancer Chat forum is also here for you whenever you need it and we have a team of nurses available if you need to speak to someone about your husband's cancer. You can call the freephone number 0808 800 4040, lines are open 9 to 5 Monday to Friday.
