What do Non-Hodgkin's victims have in common?

There are 3 cases of this decease in my family. I just wonder if there is anything in common with other victims since the seem to be so far appart geographically.

By the way they are realted by blood. But before that there was no history. Why all of the sudden? So I come to question if there is something in common with other victims. Maybe the background in farming for example, or close proximity to something?

If they're all in your family, it could be genetics. However, that would only make sense if the three family members were connected by blood lines (not by marriage). For example, if one of the three was your brother, and another was the wife of another brother of yours, the two wouldn't have any chance of being genetically related.

Kind of confusing, but I hope it helped a little.
