Sorry to hear about your Mom. My husband 53 yrs. old was also diagnosed with stage 4 stomach cancer surgery not an option 7.4 liters of fluid drained after his 5th chemo treatment and all cancer. The chemo is not working ,he was getting was taxotore cisplatin & 5FU(not sure if spelled right) He will be starting new meds we will find out this Fri which one they will be using. But everybody reacts different to treatment.
My husband was diagnosed in Feb 09 had 5 treatments so far and still working on off chemo weeks. His attitude is great which helps alot.
My prayers are with you & your Mom
hope all goes well
