They were Chemist and worked in laboratory to do with air and water pollution.
My question is :do you know any body who has worked in this field,dying of this kind of cancer ?

Sorry to hear of your loss. I know people who worked at a water pollution control facility who have died from different types of cancer. I'm sure it's related to the environment some kind of way. Good Luck!

My g andmother died of the same kind of cancer she only lasted 6 months after she was diagnosed, but she was a homemaker, she was never around any kind of laboratorys or anything like that . so maybe you should look into it online goodluck with a good answer.
