I am posting this on behalf of my father who is a Hodgkins lymphoma survivor. He completed his chemotherapy a few years back and has been okay since. He is now almost 60 years old. The problem is that he is considering buying a gas station and is serious about it however has not considered any health implications. He would be pumping gas the majority of the day and be exposed to benzene and car fumes. He already has an increased risk due to his history and this exposure would not make it worse. I am trying to convince him to do something else but am I wrong to do this?
