Hi my friend was diagnosed with a 15cm cyst in her ovary and a week later was admitted in hospital as she lost her memory and couldnt even recognise her family. She s been in hosp for 2 weeks and has had the cyst (malignant tumor) removed. They coma induced her since she was admitted until 3 days ago. How long would it take for her to gain conciousness? Could familiar sounds/noises help her to wake up? Thanks
