If a family member has terminal cancer, how will you tell him the real condition?

I think there is a premise that needs to be clarified first, that is, did your elders realize their real illness during the treatment? My friend's mother had a similar situation before. At that time, she was highly suspected of having cancer, but she was not diagnosed. The doctor said it was probably lung cancer, and her family was frightened, but they were afraid to tell her the truth. She lied to her kindly that it was tuberculosis, but her mother was very sensitive. In the process of complicated examination and treatment, she realized that her condition was not that simple, and even imagined that her condition was more serious, which backfired ... so I suggest you make this clear first to prevent this from happening. If the elder doesn't realize his illness, and it's really hopeless, I don't think it's necessary to tell him the truth to scare him. It may also be a good choice to know if he has any wishes from the side. His family will act as his executors in The Bucket List, so it may be a good choice for him to spend his life without regrets.
