Esophageal cancer

My Aunty was been diagnosed with esophageal cancer last Dec, she's been receiving treatment with chemotherapy then, immunotherapy and latterly radiotherapy on a lump that appeared on her neck. The day after her last treatment she was admitted to hospital. She's not in a good place now with her health, she has a box with her to help with the pain, with I am assuming is a morphine? The Dr's aren't forthcoming with info and its impossible to speak to the ward to gain updates on her. Ard you able to give a time frame on the info that I've given as to how long she will be with us?

Thank you in advance of your thoughts
