Hi and welcome to HCM.
Well, this is obviously termial malignant disease. This mass can be tumour or lymph
nodes enlargemnets. Whatever it is it isnt good sign. It is always hard to predict life expectancy. Statistics say 3-6 months,but it depends form case to case and her general shape. The mots importnat is her lung and heart function. Chemo is considered to prolong life for 6months-1year but it is always doubtful can patient bear it and will it have effect. In temrinal stages when life expecatncy is less than 2 months it is not advisable to go through chemotherapy
. Wish you good health.
