ANYONE had stem cell transplant who ended up with disease in different location during/post stem cel

Diagnosed with diffuse large b cell non hodgkins lymphoma... Nothing in lungs or chest area, only in abdominal prior to sct...
Post stem cell ~8th day went back with low fever what they thought to be pneumonia was finally diagnosed with same lymphoma in chest and lungs few days later...
Passed away less than a month post sct...
Need to know others in similar situation it's very hard to deal with ESP when you go home thinking of just being careful for a yr...
Thank you.
