My father who ois 79 july 4th has stomach cancer he had most of his stomach removed and it is in 20 out of 26 lypmh nodes, no metastis, he is fixing to do radiation and chemo combo, they told him if he does this it will give another year and if no treatment 4 months. i know he is going to be really sick, the treatments last around 4 to 6 month. i am so confused if he should do the treatments or not. He has alrady lost 30 lbs and is very weak, any input would be welcomed.
