Lung cancer and lack of fruits and vegetables in diet

Mr Albert Soonata, a neighbour of mine, died of lung cancer at the age of 49+ just before Christmas 2011. He died three months after diagnosis.

I met his sister-in-law last week. She told me that Mr Albert Soonata did not eat fruits and vegetables when he was alive.

He drank beer often at night and smoke cigarette. He liked to eat meats.

Did his lack of fruits and vegetables in his diet have anything to do with cancer?

May I have your comment?
