[|AI|]  Hi, Thanks for writing in. Sorry to hear about the progress of cancer in your mother-in-law. A stage 4 cancer can have a survival from 6 months to 2 years. She must fight the battle with cancer till the end. As it is not clear from your query regarding the area of cancer involvement, Marcela is given for many cancers including those of lung, pancreas and I think she is having one of these. While a lung cancer patient might have a longer survival and unfortunately a pancreas cancer person does not survive much. For her appetite, it is important to give her frequent small feeds containing good amounts of proteins. You can try giving her foods that she likes and reduce the time gap between meals. Occasionally you can also give her protein Chat Doctor.  Please do not worry.
