New to this and scared

Hi I’m hoping someone out there can help me. My husband was diagnosed last Tuesday with prostate cancer on both sides that has spread to his pelvic bone and these last few days have gone by in a blur with constant tears, worry and our whole day taken up with thinking about the future and even if there is one.  It’s so so scary and actually makes you realise how much you take for granted. My husband has already started on hormone therapy and has a bone scan booked on Monday to check the cancer hasn’t spread to any other bones. I’m trying to stay positive but he is convinced that the bone cancer has spread and that his not going to get through this and that bone cancer is incurable. Is this true? Please someone help me and give me some positive feedback
