i am a medical student but i feel so much depressed and helpless.i suggested an ultrasound abdomen for my dad who is 60.there was no indication behind it.my dad was healthy,very much active.it showed few paraaortic nodes.we did a CT abdomen followed by laparoscopic biopsy.i cant believe he has a follicular lymphoma grade 3,stage 2.he has few para aortic noses and mesentric nodes,largest being 2.6 cm.can anyone tell me anything about his long term survival?
