NO IT DOES NOT!
Having a family member with non-hodgkin's lymphoma (nhl) may only put you at a slightly increased risk of getting it yourself.
But most people who get nhl don't have a relative who has had it, so it isn't a major risk factor. Here are some of the other possible risk factors:
1. Immune system deficiency
2. Automimmune disease
3. Exposure to certain chemicals or radiation
5. Certain infections.
