Wow I didn't even realize that mantle cell lymphoma could go in your eye but I suppose it can pretty much go wherever lymph fluid carries it.
I have follicular lymphoma and on august 6th and 7th I will have my last treatment after 2 years and 4 months. Though it won't be my last forever, just for this round. Follicular lymphoma always relapses though they can never say when. I wanted a stem cell transplant right off the bat (I'll be having one when I relapse anyway) because I would rather get it over with and have a shot of being cured now, than to go through chemo again next time plus stem cell transplant chemo.
I was 25 when I was diagnosed so very young compared to most people with this form of lymphoma. It sucks at my age to be diagnosed with an incurable lymphoma, but like you I try to stay positive :)
