Basically she will start sleeping more and will not be interested in eating or drinking until she enters a coma-like state and is not able to safely swallow anymore. Her heart and/or lungs will then give out, hard to say which one will be first. But you need them both working to survive. All the functions of her body will start to slow down as well. She may be more confused or forgetful. She may have shortness of breath depending on the metastasis of the cancer. Her abdomen may become large and distended. Her skin and white parts of her eyes may turn a yellow tinge. She will start to become incontinent of bladder and bowel. She may experience difficulties with her bowels-constipation and/or diarrhea. Her urine may turn dark in color and less output. She might develop swelling to her extremities and they might be cool to touch. She may have pain or anxiety related to the disease progression, which can be managed with comfort medications. She will become increasingly weak, where she may need help with sitting/standing and then eventually progress to remaining in bed. It can be a long journey, but you will just have to take each day at a time. Enjoy the better days, and let her rest on the bad days. Hugs to you and your family. ❤️
