Is Hodgkin's Lymphoma hereditary?

My dad had some sort of cancer on his neck (I'm pretty sure it's Hodgkin's Lymphoma) and had to go through lots of chemo. I think they said he was around pesticides growing up (in Louisiana) so this may have contributed to it. I don't know anything about cancer, but sometimes i worry i might get it. Is it hereditary? if so, what is the chance (percent?) that i may get it?
