So I haven't read every page of the topic. Have you found out whether or not the growth on your lung is a tumor?
I was watching the National Geographic channel today, and there was this show called Beyond Tomorrow that did a segment on new cancer treatments being developed in China. It was specifically developed to battle liver cancer, but if I remember correctly then it could be used for other types of cancer as a safe alternative to chemo without the nasty side effects. They already have used it on humans and have prolonged the lifespan of terminal patients by double their original expectancy.
I went to the website and couldn't find any info about the show I saw today. Here are some other links that might prove useful, though.
