Thank you, I'm sorry to hear about your dad.Swollen Goat said:My dad got lung cancer for smoking for upwards of forty years. Took out 2/3 of his...right (I think? it's been a while) lung, and he did well for years but died of colon cancer which the doctors couldn't determine if it was a metastasis from the lung or another primary site. Good luck to you and your family.
