Hi Tash, my husband was diagnosed with Follicular Lymphoma in 2011. He had long term immunosuppression before then, for eczema, but at that stage his Oncologist was unwilling to draw a direct causal link. My husband had 6 months of chemotherapy (Bendemustine and Retuxamab, he was part of the BRIGHT study), and is now doing really well (He's going to cycle up Mount Baw Baw tomorrow- for fun?!!?!!) Good luck to you and your son- let us know how he goes. This is a great place to come for support, venting and asking questions. love and hugs, Emily
