Lung cancer and nigella sativa oil

Hello,
My father is 65 years old and since february 2007 he was dignosed with lung cancer. He has been treated with chemiotherapy up to now. Last check up showed that despite chemio his disease has progressed.
Lately I have read a lot of articles about nigella sativa oil.
Does anybody knows about its effetcs in the case of lung cancer?
Please, I need help.
thanking you in advance
